Security Problem With UDP Port
Dec 27, 2007
hi
at first i apologize u for bad english.
my sqlserver2000 works on Win2000 for many years in a wide network.
i have problem that it used 1434 UDP port to increase bandwidth traffic by sending many UDP packages to many IP which created randomly by SQLServer2000 when it find another SQLServer2000 after sending packages again new server start sending UDP Package to other.
then no one cant connect to Server.
i had a worm like this 2 years ago.

Hey all.I'm running SQL server 2000, on W2K server. All the latest patches/etcfor both installed.I've a need to allow remote access to the DB. I have a strong passwordon the sa account, and have completed the various security checklistson the MS website, including running the baseline security program theyprovide.Due to the nature of the application, windows authentication is notpossible.Besides someone trying to hack in via a password guess, are there anyother things I need to worry about? Again, all the latest patches andwhat not are installed.ThanksMatt

Hi,
I have posted this issue for a week, haven't got any reply yet, I posted it again and desperately need your help.
The article http://msdn2.microsoft.com/en-us/library/ms365343.aspx says:
Model Item Security can be set for differnt security filters, but when I use SQL Server Management Studio to set Model Item Security, it seems "Permissions" property surpass "Model Item Security" property. -- My report server is using Custom Authentication.
For example, in "Permissions" property of the model, if I checked "Use these roles for each group or user account" without setting any user or group, no matter what users I added to "Model Item Security" with "Secure individual model items independently for this model" checked, NO one user can see the model on report manager and report builder;
in above situation, if I added "user1" and gave role such as "Browser" role to "user1" in "Permissions" property, if I checked "Secure individual model items independently for this model" in "Model Item Security" property, even I did NOT grant "user1" to root model and any entities under the model, the "user1" is able to access the model and all entities in report builder.
My question is on the same report model, how to set "AdminFilter" (empty security filter) for administrator permissions and set "GeneralFilter" (filtered on UserID) for general user based on their UserID?
The article also says:
"Security filters are always applied, even for users who have Content Manager or Administrator permissions to the model. To allow administrators or other users to see all rows of an entity on which row-level security is defined, you can create an empty security filter (which always returns True) and then use the filter to grant those users access to all the rows."
So I defined 2 filters "GeneralFilter" and "AdminFilter" for "Staff" entity for my report model "SSRSModel", I expect after I deployed the report model, the administrator users use report builder to build reports with all rows available, and the non-admin users can only see rows based on their UserID.
I can only get one result at a time but not both:
either the rows are filtered or not filtered at all, no matter how I set the "SecurityFilter" for the entity: I tried setting both "AdminFilter" and "GeneralFilter" for SecurityFilter at the same time, combination of "DefaultSecurityFilter" and "SecurityFilter", or one at a time.
Your help is highly appreciated!

I have Sql Server Express installed on Vista (service pack 2)
I have Visual Studio 2005 with an application that I'm trying to access it with within a WCF service.
The login ID of the service is added to the database.
The database has remote access turned on.
The ID is granted access to all databases within the server.
The thread is being set with WindowsProvider and the services set their thread to WindowsProvider.
The dataserver is set with using Windows Authentication for security.
When I open my connection to the database, though, it reports the typically useless message that the connection is not allowed and that the server may not allow remote connections.
How to I get past this? I've done everything right.

Hello,
I hope someone could help me out here.....
I have set up a new web server in my DMZ. This web server needs to "talk" to an application server located on my LAN. It communicates via a COM + Component.
I would like to keep the access that is open between the DMZ & LAN to minimal, obviously for security reasons. Does anyone know what port is used for COM + communication?
Thank you!

Ok,
The Scenario is as follows:
24/7 Production Call Centre server running NT4.0 and SQL 6.5 with all the latest service packs.
SQL mail fails(with dull regularity) and the SQL server services stop.
When the SQL server Services are restarted an error message appears stating that Port 1433 is in use after which nobody can connect via TCP/IP. Obviously the port believes the previous SQL session is still running, and won't release the port to the "New Application requesting it".
On a unix system you can force a port reset so you don't need to shutdown and restart the box. Can you do this from either SQL or NT?
Any solutions would be greatly appreciated the DBA's are 100 Miles from the Servers, so restarts are reliant on other people!

Is there any way that I can avoid using 1433,1434 port on the clustered servers?
I have a active/passive (SQL1-active,SQL2-passive) cluster server and another active/passive cluster (SQL2-passive,SQL1-active).
(Its a Quassi active/active server)
I want to change all the sql server ports to other than 1433 and 1434.
Should I change in the registry
Localmachine-software-microsoft-mssqlserver-client-supersocketnetlib-tcp
or
Localmachine-software-microsoft-mssqlserver-mssqlserver-supersocketnetlib-tcpport
or
anywhere else?
Any suggestions are always welcome

Does anyone have an idea on why when using IP with port 1433 that on the SQL 2000 Server a bind failure happens on port 1433 and are not able to get to the SQL using IP but you can use Named Pipes.
Would greatly appreciate any help.

I've been diagnosing deadlocks for a last couple weeks at a client site and I understand the KEY: and TAB: locks issues. However, the client recently experienced a series of multi-branch deadlocks for which I can find no information. Attached is the deadlock text from the ERRORLOG. Any help would be much appreciated.

Did a search on port 1433 but nothing came up in the search.
This question is more geared to DBAs more then SQL developers.
I have a SQL 2000 server on a win2k3 machine. For some reason it will not listen in on TCP port 1433.
Shared memory and Named Pipes do though.
I checked the Server Network Utility and I see TCP/IP listed right under Named Pipes and I see that the default port is 1433.
Any ideas how to get SQL to listen on that port?

2. quick way to change the port number?

I'm trying to setup SQL Server 2005 Express to communicate through a non standard port. I can connect to SQLServer on a remote machine using port 1433 when it is set as such but when I change the server to another port and try and connect using SSMSE I can't get through. I'm specifying the ip address and a colon followed by port number to connect.
For example: 123.123.123.123:1234
Any ideas?

Not sure how this particular topic should be labeled but I figured I would start here.
I have a third party Time and Attendance program that uses SQL 2000 and IIS on top of Win2003.
It also uses a client side program that sits on an XP box that pulls Time clocks entries than passes that info to the SQL server.
We recently needed to move to a different service, still utilizing the same Time and Attendance program but a different client utility that pulls the Time clocks. Both the client and Time and Attnedants program are developed by the same company.
All that being said the new clock utility cannot connect to the SQL service.
The difference between the 2 utilities is the first utility uses UDP, the second uses TCP and requires port 5405.
Basically the way I€™m seeing things is that the server does not have port 5405 open this also confirmed by the company the wrote the program.
There is no firewall on this server. RRAS is installed but does not have any filters enables which I believe means it will receive and pass all protocols to all ports.
Using a port scan utility it shows port 5405 not to be open
How can I get port 5405 open?

Hi:
Just wanted to find out what port does SSIS utilizes when communicated with a remote SQL Server. Is it 1434, 1433 or something? I have a SSIS Package on Server 1, which which does inserts on SQL DB on Server 2. I think between Server 1 and Server 2, some ports are being blocked because the 2 servers are separated by a firewall. When SSIS makes connection to Server 2 (SQL), what ports does it use? Also, any other tips would also help. Here is the error I am getting:
Cannot connect to 10.xx.xx.xx.
===================================
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)

The powers that be at my company have decided to redisign our network. The big change is that they are completely separating the two domains, whereas I guess right now one runs inside of the other.
What this means to me is that I need to get a document together which shows all the connections between different SQL servers, web pages and services that I've created over the last year.
My question is, what ports do all of these things use to communicate with SQL Server 2000? I believe the only connections right now are using ADO/ADO.NET, or straight SQL Linked Servers.

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?

In an environment where there are many initaitors speaking to a central target with frowarders in between, from what i can understand this best policy is to disable encryption on the endpoints, since dialog encryption will be enforced this is all that is really required, is this correct.
If the endpoints used encryption the message would need to be encrypted and decrypted at each forwarder resulting in slower perfromance, where as dialog encryption would only encrypt at the sender and decrypt at the target, so is this the best way to go?
Secondly is it best practice to open a dialog initally and send messages over this dialog for years never ending the conversation? This way the services only have to authenticate eachother once, if there are no reboots etc that is of course.
I would think performance wise sending each message and ending the conversation each time is a much greater overhead ? So would it be best practice to keep dialogs open and keep sending messages ?
Initally when i was learning service broker i thought that one must send a message and end the dialog until the next message, but i think the other way is the best option ?
Is this correct ?
Thanx

Hi
I'm designing a distributed application where I will have SQL Server 2005 distributed databases replicating data to my central hub which is again a SQL Server 2005 database using SQL Service Broker. Data will be sent from the central hub to the distributed sites and vice versa. I need to authenticate the communication and also secure the communication by encrypting the messages. Which security shall I use? Where do I configure the type of security being used? What is the difference between transport security Vs dialogue security - Full security model?
Thanks
