SQL Security :: Windows Server Firewall Not Blocking SSMS Access From All IPs
Nov 6, 2015
We have a hosted server with a website and sql server 2008 on.
The windows firewall is turned on for all networks / profiles and says its blocking incoming traffic.
I see a lot of login attempts in the windows logs where hackers are trying to connect to it. I can also access it via SSMS from multiple external ips.
Everywhere I've googled says that incoming traffic should be blocked by default by the firewall.
There are no obvious rules that allow SSMS access.
If I do a blocking rule on inbound rules for a single ip that does work, blocking it from that ip, but any other ip's can still connect.
In the firewall log file I can see the allowed connections on port 1433 etc. other than the dropped one from the test blocking rule.

I have trying to access a 2nd SQL Server instances running on my WHS 2011 server from my Windows 8.1 Pro client.
The first SQL Server instance I installed is SQL Server 2014 Developer. This has been in place for many months and access from my client pc is not a problem. The Developer instance was installed using standard settings so uses TCP port 1433 and I have verified this by checking the firewall rules. This instance name is <SERVERNAME>
As I want to host a personal website on my server I installed SQL Server 2014 Express as a 2nd instance on my WHS 2011 box for website database purposes. After this installation both instances are accessible via Management Console on the WHS 2011 box.Â
The second instance is named as <SERVERNAME>SQLEXPRESS.
However, I am unable to access the SQLEXPRESS instance using Management Console on my client pc. I know it is a firewall issue as when I turn off the firewall on the WHS 2011 box I can connect successfully. The errors reported have resulted in my trying many things to resolve the problem but none have worked, e.g.
Use the default SQLEXPRESS instance to listen on all TCP ports (default installation option). I checked the necessary firewall rules were set up correctly and they were, i.e. UDP ANY and TCP ANY for the SQLEXPRESS sqlservr.exe file.
Change the default SQLEXPRESS instance to list on a specific TCP port, e.g. 19344
Create an ALIAS for the SQLEXPRESS installation
The instance is definitely set up for Remote Access and is not Hidden.
Are there any other firewall rules I need to apply?

Hi all,
I have a Windows Server 2003 with SQL Server 2005.
I´ve configured the following itens to allow remote connecitions:
[code]
WORKAROUND
Warning If you use Registry Editor incorrectly, you may cause
serious problems that may require
you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using
Registry Editor incorrectly. Use Registry Editor at your own
risk.To work around this problem, follow these steps on the
computer that Windows XP SP2 is installed on:
1. Make sure that the Log On As account for the MSDTC service
is the Network Service account. To do this, follow these steps:
a. Click Start, and then click Run.
b. In the Run dialog box, type Services.msc, and then click OK.
c. In the Services window, locate the Distributed Transaction
Coordinator service under Name in the right pane.
d. Under the Log On As column, see whether the Log On As
account is Network Service or Local System.
If the Log On As account is Network Service, go to step 2.
If the Log On As account is Local System, continue with these steps.
e. Click Start, and then click Run.
f. In the Run dialog box, type cmd, and then click OK.
g. At the command prompt, type Net stop msdtc to stop the MSDTC service.
h. At the command prompt, type Msdtc €“uninstall to remove MSDTC.
i. At the command prompt, type regedit to open Registry Editor.
j. In Registry Editor, locate, and then delete the following subkey:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTC
k. Close Registry Editor.
l. At the command prompt, type Msdtc €“install to install MSDTC.
m. At the command prompt, type Net start msdtc to start
the MSDTC service.
Note The Log On As account for the MSDTC service is set
to the Network Service account.
2. To allow the network transaction, you must enable
MSDTC. To do this, follow these steps:
a. Click Start, and then click Run.
b. In the Run dialog box, type dcomcnfg.exe, and then click OK.
c. In the Component Services window, expand Component
Services, expand Computers, and then expand My Computer.
d. Right-click My Computer, and then click Properties.
e. In the My Computer Properties dialog box, click
Security Configuration on the MSDTC tab.
f. In the Security Configuration dialog box, click to
select the Network DTC Access check box.
g. To allow the distributed transaction to run on this
computer from a remote computer, click to select the Allow Inbound check box.
h. To allow the distributed transaction to run on a
remote computer from this computer, click to select the Allow
Outbound check box.
i. Under the Transaction Manager Communication
group, click to select the No Authentication Required option.
j. In the Security Configuration dialog box, click OK.
k. In the My Computer Properties dialog box, click OK.
3. Configure Windows Firewall to include the MSDTC
program and to include port 135 as an exception. To do this,
follow these steps:
a. Click Start, and then click Run.
b. In the Run dialog box, type Firewall.cpl, and then click OK.
c. In Control Panel, double-click Windows Firewall.
d. In the Windows Firewall dialog box, click Add
Program on the Exceptions tab.
e. In the Add a Program dialog box, click Browse,
and then locate the Msdtc.exe file. By default, the
file is stored in the Installation drive:WindowsSystem32 folder.
f. In the Add a Program dialog box, click OK.
g. In the Windows Firewall dialog box, click to select
the msdtc option in the Programs and Services list.
h. Click Add Port on the Exceptions tab.
i. In the Add a Port dialog box, type 135 in the Port
number text box, and then click to select the TCP option.
j. In the Add a Port dialog box, type a name for the
exception in the Name text box, and then click OK.
k. In the Windows Firewall dialog box, select the name
that you used for the exception in step j in the
Programs and Services list, and then click OK.
[/code]
But, when the Windows firewal on the server is "On", remote connections
are not allowed, despite I´ve configured the Exceptions on the firewall.
Is there another task to solve this problem?
thanx!!!!

If we have a "pool" SQL login, a one that uses SQL Server authentication, and this login is used by different domain account to access SQL Server, is there a way to audit which domain account used that "pool" login to do something on a object in SQL Server? I have to keep this way of accessing SQL Server, so how to create a login for every domain account accesses SQL Server

I am using SQL Server 2005 Express + SP1 on a Windows Small Business Server(SBS) box. The SBS is connected to a client thru LAN.
Following are what I gave as IP address and DNS on the server:
IP: 192.168.16.2, subnet mask : 255.255.255.0, Preferred DNS server: 192.168.16.2, Default gateway and Alternate DNS Server blank
On the client, I have,
IP: 192.168.16.4, subnet mask : 255.255.255.0, Preferred DNS server, Default gateway and Alternate DNS Server blank
I can ping and connect to either of the machines.
If I do a sqlcmd -S "tcp:servernameINSTANCE,port", I get the following error message:
HResult 0x80090304, Level 16, State 1
SQL Network Interfaces: The Local Security Authority cannot be contacted
Sqlcmd: Error: Microsoft SQL Native Client : Cannot generate SSPI context
If I do a sqlcmd -S "tcp:192.168.16.2INSTANCE,port", it connects to SQL Server.
I have the Windows Firewall ON. If I Off the firewall, I do not have any problem at all.
I included File and Printer Sharing, sqlsvr.exe in the Exception list of the Windows Firewall.
Any help to solve the issue is appreciated.
Thanks.

Hello,
I have purchased 4 new boxes for SQL2005 and my var database product all running on the new Windows 2008 server. A lot of silly mind bender issues but I am up and live now. However, what should the firewall settings be on my SQL database box? I have ultimately turned off Windows Firewall so that I could connect and continue forward.
Thanks!

Deleting a Login from a server instance and adding it back did not show that the login was still mapped to databases. In SQL Server 2008, adding a Windows Login did not permit access to end user databases until the Windows Login was mapped to various databases. In SQL Server 2012, once a Windows Login is added to SQL Server Security, it may access ANY end user databaseWe use the following to circumvent this problem, Windows Login by Windows Login: DENY VIEW ANY DATABASE TO [TESTTest1]

I know from searching this forum that there have been many variations of the issue I'm currently suffering, but I haven't found anything quite like mine or a solution to solve it. The issue I'm running into is that I am unable to log on to Reporting Services using Management Studio or the web interface when Windows Integrated Security is enabled. I have full functionality using basic security, but the risks involved make it impossible to deploy basic authentication out into production. The error I'm receiving in Management Studio is The request failed with HTTP status 401: Unauthorized. (Microsoft.SqlServer.Management.UI.RSClient). I recieve the same error when I try the web interface.
I've looked the most recent logfile in WindowsSystem32LogFilesW3SVC1 and these entries match up to the time I attempted my authentication.

I tried to highlight one of each of the HTTP errors I am getting. 401.2 and 401.1 are the ones I kind of expected, but have no idea why I'm getting them. The 500 0 error is a bit troubling, because unless I'm mistaken thats a server side error.
Here's my current setup. As far as I can tell, I've done everything to set up correctly for Windows Integerated security.
My Specs
The server machine running all SQL 2005 services. It resides in a domain. All Clients are in the same domain.
Intel Dual Processor 3.20 gig Xenon
Windows Server 2003 w/ SP2
Microsoft Sql Server 2005 w/ SP2
Reporting Services Setup
The virtual directories Reports and ReportServer are set to Windows Integrated Security with Anonymous Access disabled. All other checkboxes in Directory Security are unchecked. For permissions in Reports, I have:
Administrators (servernameAdministrators) - Full Control
ASP.NET Machine Account - Modify, Read & Execute, List Folder Contents, Read, Write
Authenticated Users - Modify, Read & Execute, List Folder Contents, Read, Write
Creator Owner - No permissions
Domain Users - Read & Execute, List Folder Contents, Read
SQLServer2005ReportingServices]WebServiceUsers$... - Read & Execute, List Folder Contents, Read
SQLServer2005ReportServerUsers$... - Read & Execute, List Folder Contents, Read
SYSTEM - Full Control
Users (CompNameUsers) - Read & Execute, List Folder Contents, Read
In ReportServer I have the same permissions except Authenticated Users is absent.
At one point, I even added the account Everybody and gave it full control, and I still recieved a HTTP 401 error. Any help at what I might be missing would be a godsend.
Thanks.

I am trying to install SQl express as part of a custom app.I have been able to use the template.ini to pass in all the parameters and install. installs fine,however the installation isnt browseable by remote machines due to the sqlserver.exe and sqlbrowser.exe not being in the windows firewall list. How can i add then to this list automatically at install time? or is there another way around this?

We install SQL Express 2005 with a custom named instance. Since a named instance uses dynamic ports, how can I add this named instance to the Windows Firewall exception list? Previously with MSDE 2000 we installed as default, then I added port 1433 to the Firewall exception list.
Is there a way to install SQL Express to a static port (programmatically)? Or, is there a better method, like adding the SQL custom named instance service to the firewall exception list?

Hi there!
I am facing this problem:
I have server A (SQL Server 2005) in LAN and server B (IIS 6) in DMZ.
Due to security policies, server A can initiate communications to B through a firewall; server B cannot initiate any communication to server A.
A web application on server B needs to interactively read/write data stored on server A.
I was reading something about repication, sql everywhere, service broker and something else.
Is there some integrated functionality in SQL Server 2005 that can help in this scenario, or should I develop some sort of sync application?
Thank you.
Bye!

I have a windows 2008 with SQL Server 2008 R2 VM on Azure. I am trying to connect to the SQL server for the first time using SSMS, but have not been able it. I have a VPN tunnel, so I am connecting using Windows authentication. The error I get back from SSMS is:
Login failed for user 'domainusername'. (Microsoft SQL Server, Error: 18456).In the event viewer I see this error message: Login failed for user 'domainusername'. Reason: Token-based server access validation failed with an infrastructure error. Check for previous errors. [CLIENT: <local machine>]
I have done the following:
- created an endpoint for port 1433
- opened port 1433 in the firewall
- Ran the MSSQLSERVER service as the build-in users Network Services, Local System, and Local Service, and as a local and domain administrator, with the same exact result each time.
- I get the same result trying to connect locally or remotely.
- I get the same result trying to connect using sqlcmd.

In my architecture I have a Domain Controller with Active Directory (DOMAIN_A), IIS 6.0 (WEBSERVER) and SqlServer 2000
(SQLDBSERVER).
The WEBSERVER has a
.NET application with windows authentication. The .NET application interacts with the
database server. I want to use Integrated Security to pass in
the users login credentials to the database to run any database calls so that I can
audit who is making what calls on the database.
The connection string
I am using for this is as follows:
string connStr =
"Server=SQLDBSERVER;Database=xxx;integrated
security=SSPI";
The problem arises
after I login to the web application (I use the user DOMAIN_ASomeUser where
SomeUser is a user who has permissions set up to make all of the database
calls). After logging in however, when I go to a page that makes a database
call I get the following error:
System.Data.SqlClient.SqlException: Login failed for user
'DOMAIN_AWEBSERVER$'.
It seems that for some
reason, .NET is not passing the login name SomeUser, but instead is passing
SERVERNAME$. Would anyone pls have any ideas how I can implement this. Any guide or references would be much appreciated.
Thanks in advance.

if you run the following script it takes access from the windows admin from getting into sql server through windows auth. The issue is that the files that are attached logging as SA after that are read only. Is there any solution? When you try and switch the file to read write sql server gives an error saying that it cant read the mdf and ldf--gives a windows access error....

Hi,
I am new to internet development and would like some advice on the technology used to access a SQL database that sits on a network behind a firewall.
** ASP .NET Page ** -> ** Web Server ** -> ** FIREWALL ** -> ** SQL **
So to give an example; from an ASP .NET page on the internet, I would like to populate a DataGrid with the contents of a single table from a SQL database. The SQL database is sitting on our company network behind a firewall.
Could someone please explain / point me in the right direction in how the ASP .NET page / Web Server can securely access the SQL database.
Thanking you in advance

Hi All,
I am facing a strange issue with accessing data from SQL server 2000. We are using SQL Server authentication for connecting to SQL Server 2000 and ADO .Net SQL client in the application. The problem here is, we have databases installed in one of the servers in some other office location that is in different state but on same domain. We do development from two locations that is one from Virtual Machines hosted on servers where Database Servers are located and on our local desktops in India.
Now when I developed a test client in Virtual Machines which will call a web service to get datasetof some data and show them in DataGrid. When I run the test client in debug mode from Visual Studio 2003, then I am getting data in the DataGrid. Even when I just run the exe from Virtual Machine still I am getting data.
But when I copy debug folder of the test client to the local desktop in India and when I run the Test client I am not getting any data loaded on to the DataGrid. I am getting an empty dataset when I am running from the local desktop.
Also I have converted the VS2003 project to VS2005 and when I run the application from Local Desktop then I am getting the data loaded fine. I could not understand what is the problem, what is the difference between accessing data from VS2003 and VS2005 using webservice.
Is this a firewall issue or I am missing any thing here. The webservice method I am calling to get data is actually returning dataset when I am calling this method directly from the browser also and even through application in virtual machine.
I am still not able to come to terms with this problem. This is severely affecting our deployment. Please help us resolve this problem. Please let me know if you need more information.
Thanks,
Venkatesh

Greetings Folks,
We have a SQL Server Reporting Services instance running SP2. I have attempted to add a domain group in a trusted domain to the server to enable regular users to access reports. I have added this group to the instance folder as a SYSTEM USER and home as BROWSER. I am allowing those settings to be inherited down through the folders (reports and data sources) to the reports. My test user in this report receives:
The permissions granted to user 'DOMAINuser' are insufficient for performing this operation.
(log shows HTTP 500)
when the user attempts to use the URL to go directly to the report. If we try to navigate from HOME and walk the folders the user sees a blank HOME page.
I have used other groups with no problem.
Is there something I am missing in setting up the security environment? Any help would be greatly appreciated.
Thanks, Mark

I have two SQL Server machines - RPTPROD and DATAPROD.
I wanted to create a linked server from RPTPROD pointing to DATAPROD using Windows Authentication. Â When I tried to create this linked server, I keep getting this error
"Login failed for user 'NT AUTHORITYANNOYMOUS LOGON' (Microsoft SQL Server,Error: 18456)". Â
On the "Security" page, I chose "Be made using the login's current security context". Â I'm sysadmin on both SQL Server machines. Â

I have a scenario where I want to make a linked server query and report using windows service account credential. I can able to do link query if I RDP into the Server where linked server established using the service account and run query successfully  but local client SSMS with my credential fails connecting linked server or querying. Looks to be a sql double hoping problem if so configuration each client domain account to enable delegation will be challenging as mentioned in the following articles instead service account only might work if possible.

CLIENT SIDE:
If the query is reading from large table, (100 columns x 20000 rows)
I have no problem getting results using SQL Query Analyzer on the Client side.
However, I am getting timeout problem from the client side application.
The query failed. The message from the database engine was:
Microsoft OLE DB Provider for SQL Server: Timeout expired.
SERVER SIDE:
I tested the same query on the server using the application. I can get the results.
ENVIRONMENT:
Server machine:
The Server : Windows 2003 Server SP2
Database Server : SQL Server 2000 €“ (8.00.2039 Standard Edition SP 2)
linkserver (OLE DB 9.0.0.3504 ) to FoxPro 9.0 SP1 table
SQL Server Timeout Settings: Query time-out (sec, 0=unlimited)
Client machine:
Windows XP SP2 : Windows Network Authentication
SQL Server 2000 client
For some reason my environment doesn€™t like the outside application to connect to the server long time?
Do you have any idea how to fix this timeout problem? Do I need to configure DCOM or DTC?

I have new Dell XPS13 Laptop with Windows 10 Pro, which I plan to use for development. Â Installed vs2013 and SQL Server 2012. When running SSMS and invoking any of the tools, e.g. create new database, copy database etc. The controls in the dialog boxes are scrambled, i.e. overlaying each other or partially out of the viewport, making SQL Server totally unusable. Â Uninstalled SQL 2012 and installed SQL2016CTP3 and got the same result.
The display is Intel HD Graphics 5500 using a recommended 3200 x 1800 resolution. It appears that SSMS visuals do not scale correctly. Changing the resolution offers no support and in fact lower resolutions do odd things like leave snail trails and do rapid flashing screen repaints.

I just installed sql server 2014 on a second pc I will be using to vpn into our parent company's domain. When I use explorer to look at file system folders on servers in the parent domain on which I have permissions, I am prompted correctly for my windows creds in their domain which are different from the creds in my originating domain and I can see those files. But when I open ssms and try to connect using server name or ip address, I see two problems....
1) ssms is using my originating domain creds without giving me the opportunity to change them
2) whether I use a server name or ip address I get an error saying login from an untrusted domain cannot be used with windows auth 18452.

Hi;
I am looking for a way to log all security related events for SQL in Windows Security Log. I am trying to use SCOM for monitoring SQL and I am looking at ways to generate alerts in my SCOM Console for specific events in SQL e.g. A table is deleted, user is modified, deleted, etc. Is this possible and if yes how do I achieve the same?
Rgds;

I do a clean install of SQL Server + RS + SP1 with standard setup on Windows Server 2003. I create a simple report (select * from aTable). This report (actually any report) shows the error message "For security reasons DTD is prohibited in this XML document. To enable DTD processing set the ProhibitDtd property on XmlReaderSettings to false and pass the settings into XmlReader.Create method."
This has to do with security settings in Windows Server 2003. On Windows XP everything works fine.
Any help would be greatly appreciated. Thanks!
Edit: The reports do work in the preview tab in BIDS.

Have installed SQL 2008 on Windows 2008 and have come across a strange issue.
Â
When connecting to the Report Server cvia SSMS to enable "My Reports" (for example) the Report Server Properties are greyed out and we cannot alter them. This occurs when logged on both locally & remotely to the Win 2008 server.
Â
Interestingly, we have another (XP Pro) box with SQL 2008 on it. If we connect to the Win 2008 SQL report server from the XP machine's SSMS, then we have full control and can access and change the report server properties on the Win 2008 server.Â
Â
The relevant domain accounts are in the Admin group on the Win 2008 server and the XP Server so we are confused as to why we cannot edit the Win 2008 report server properties locally.

I have a new Wireless G router configured by a client for their VPN. They said to hook it up to my existing router. It works great if I try to connect to something on the VPN, Informix, SQL no problem.
I have my own SQL 2k on the same network locally. I can access the server with Maping tools but I can not get an ODBC connection to work either using Windows Authentication or SQL authentication. Tried my old router and it worked fine.
I figured it would not work while I was connected to the VPN, but thought I should be able to access SQL server when not on the VPN. Is this a port issue? Never had to deal with this.
Thanks

In the process of reviewing all Security access into our production servers, I found a user login name of 'BUILTIN/Administrators' with the type 'NT Group' in our production DB. I am not sure whether this Login was setup automatically when SQLServer was installed or it was setup by the administrator, who is no longer with the company? I was able to find out all the users in the Administrators NT group, but what threw me was the word 'BUILTIN' . Are there other Logins besides 'sa' that get setup during the install?
Thanks.
Helen
