Connection Problem Using Work Laptop When On Home Network

Mar 27, 2008

When using my Work laptop while at home, how can I log into an SQLServer Express 2005 database on a home server, using Windows Authentication, without having to VPN in and log onto the network at Work? If I VPN into work then I can connect to my home db just fine.

I have a laptop which I carry from work to home each day. I'm a Domain Admin at work so my network login name is DOMAINjoe. At home I have 5 PCs in a home network, WorkGroup is WORKGROUP. When I carry my laptop home I log in exactly as I do at work. All is fine. File sharing, printer sharing, & internet all work between my 5 PCs.

I installed SQLServer Express 2005 on a home PC I use as a server (Vista Business edition). Home server's name is STAR. I developed a database called AddressBk on my laptop (Visual Studio 2008) using my laptop's local copy of SQLServerExpress. App works fine. I copied the Db files onto my home server STAR. My user name on STAR is Joe2, so while logged onto Star as Joe2 I used Star's SQLServer Management Studio Express to connect the AddressBk db to Star's copy of SQLServer Express. All is fine.

Now if I use my LapTop on my home network and try to connect to AddressBk on STAR I get a connection error. I get the error whether connecting using SQLServer Management Studio Express or using Visual Studio 2008. The SQLServer Management Studio Express connection screen shows I'm connecting using Windows Authentication and my User Name is DOMAINjoe. I presume this is the problem as I can not add a user on Star with a Domain Name. Other PCs on my home network can connect to AddressBk db on Star without a problem. If my labtop VPNs into work then I can connect just fine.

Here is the connection string my App uses.
Data Source=STARSQLEXPRESS;Initial Catalog=AddressBk;Integrated Security=True;connection timeout=60

How can I connect to my db without having to VPN into work?

Thanks for any help.

Using Windows Authentication On A Home Network

Mar 17, 2007

Hi everyone,

I€™m quite new to SQL Server so maybe this is an easy question but I haven€™t found the answer after 3+ hours of Googling and experimenting.

I have a simple set up €“ two computers named HELEN and DELORES, both running Win XP Pro, SP2. These machines are connected via a home network and both belong to the same Workgroup. There€™s no Domain involved. HELEN is running SQL Server Express while DELORES is the €œclient€?, running SQL Server Management Studio Express. I am using €œWindows Authentication€? and Named Pipes to allow DELORES to work with the SQL Server Express instance on HELEN.

I have a general understanding of €œWindows Authentication€? and I was hoping someone could fill in the gaps. I realize €œWindows Authentication€? uses the underlying Windows User Accounts on the server to validate incoming connections.

I€™m sometimes having a problem in connecting SQL Server Management Studio Express (running on DELORES) to the SQL Server Express instance (running on HELEN). This problem may be due to a lack of understanding of Windows User Accounts.

I€™ve found that if I use the exact *same* username *and* passwords on both machines, SQL Server Management Studio Express has no problem connecting to HELEN€™s SQL Server Express instance. If I change the username and/or password on only one of the machines, the connection fails. Also, if I keep the usernames the same on both machines but I delete the passwords, the connection fails again.

I realize I can set up a user account on HELEN. Do I then have to set up the same user account (with the same non-blank password) on Delores? So far, this is the method that€™s been successful. Is it possible for me to tell SQL Server Management Studio Express to use a particular account (username/password) when connecting to HELEN via Named Pipes? If so, how is that specified?

I admit to my confusion. Any help would be greatly appreciated.

Connecting To MSDE 2000 Over A Home Network

Dec 28, 2005

Hi,

I'm trying to connect to an instance of MSDE 2000 from Visual Studio 2005 over a home network.  Although I know how to connect to a database from Visual Studio, I'm pretty clueless about configuring Sql Server to allow the connection (I can connect with no problem when I do so from the same computer).  Also, with experimenting I've created a bunch of instances of Sql Server that I don't really need and am not sure how to get rid of them.  Thanks in advance for any help.

-Dave

I don't know if this will help, but I've already tried enabling all of the network protocols in the instance.  Also, I can easily connect to an Access database over the network.

Remote Connect To SQL Server 2005 At Home From Private/office Network

Dec 18, 2007

I'm green on this networking stuff so any help is greatly appreciated.

I have setup my home computer as a server and assigned a static IP to it. I installed SQL Server 2005 Developer and allowed remote connections to it through the Surface Area Config tool, added port 1433 TCP and 1434 UDP to firewall's exception list, and started the SQL Server Browser service.

Now I can't seem to remote connect to this SQL Server from my office network. Is there something I'm doing wrong here?

Thanks!!

SQL Express &&amp; Vista Home Premium Connection Issue

Nov 29, 2007

Hi,


We have an application using SQL Express as the back end.
One of our clients has two machines both running Vista Home Premium
One of the Home Premium machines has SQL Express installed on it as well as our application - it is acting as a server.

The other machine is networked to it. The application will run but cannot establish a connection to SQL server.

I have done the following:

Set remote access on
Enabled named pipes and TCP/IP
Enabled SQL Browser
Set VIA on
Restarted SQL and rebooted the Machine.

Disabled the firewall on the host and workstation

Is there anything I'm missing here? I was able to get the installation running on a Vista Business machine to Vista Ultimate machine with no issues.

Thanks

Dropped Network Connection Breaks Connection To Local SQL Server

Apr 2, 2008

Let me set the stage of my testbed configuration: On Windows XP SP2, my default connection to the Internet is via wireless express card modem using EV-DO via Verizon Wireless. Let's call this connection A. I also have a traditional wireless network connection (802.11g) that is always enabled. Let's call this connection B. Connection A is always connected during normal business hours. Connection B is not and is often searching for a wireless network to connect to when nothing is in range.



Yesterday, connection B was continuously trying to connect to a wireless network not under my control, meaning that the connection was never established and notification messages continually popped up to complain of this fact. Over time, I've learned to ignore these messages and go on doing my daily work without much thought of the possible implications.




Then, things started to get odd. I was running our application, WebWatchBot, to perform some simple tests of various websites and servers, when I started to get messages from the application that database connectivity was lost, which is a message that pops up to inform the user that the connection is forcibly dropped by SQL Server. After a few moments, the connection to the database was re-established and the message went away. Since I was actually working with SQL Server, I thought it was an anomoly, so I continued on. Then, it happened again. And again. Then, I noticed that the "database connectivity lost" message started to coincide with the wireless connection's (connection B) inability to connect with a wireless network.




Why would this be happening? The database and application are on the same exact computer. The connection to the database is via ODBC drivers over tcp/ip, but why would connection B affect this?





Some added information that may prove useful:



Client side:

What is the connection string in you app or DSN? (please specify)
DRIVER=SQL Server;SERVER=HIGHNOTEWEBWATCHBOT;Database=WebWatchBot;UID=sa;PWD=*****

If client fails to connect, what is the client error messages? (please specify)

What is your client database provider? [SNAC | MDAC | ADO.NET1.0 | ADO.NET2.0| other (please specify] Or/And, what is your client application? [SQL Management Studio | SQL Profiler | Visual Studio | Other (please specify): WebWatchBot - Website and Server Monitoring Software
Is your client computer in the same domain as the Server computer? (Same domain | Different domains | WorkGroup)
What protocol the client enabled? [Shared Memory | TCPIP | Named Pipes].
Do you have aliases configured that match the server name portion of your connection string? NO
Do you select force encryption on server and/or client? NO
[2] Server side:


What is the MS SQL version? [ SQL Server 2005 | SQL Sever 2005 ]
What is the SKU of MS SQL? [Enterprise | Standard | Workgroup | Express (or MSDE) | other (please specify)].
Microsoft SQL Server Management Studio 9.00.3042.00

Microsoft Internet Explorer 7.0.5730.11
Microsoft .NET Framework 2.0.50727.832
Operating System 5.1.2600

What is the SQL Server Protocol enabled? [Shared Memory | TCPIP | Named Pipes ]. Use SQL Server Configuration Manager to configure it and check ERRORLOG or event log to confirm.
Does the server start successfully? [YES | NO] If not what is the error messages in the SQL server ERRORLOG?
If SQL Server is a named instance, is the SQL browser enabled? [YES | NO]
What is the account that the SQL Server is running under?[Local System | Network Service | Domain Account]
Do you make firewall exception for your SQL server TCP port if you want connect remotely through TCP provider? [YES | NO | not applicable]
Do you make firewall exception for SQL Browser UDP port 1434? In SQL2000, you still need to make firewall exception for UDP port 1434 in order to support named instance.[YES | NO | not applicable ]
[2a] Tool Used to Connect

What tool or Application are you using to connect to SQL Server (eg: Visual Studio, SQL Server Management Studio, SQLCmd.exe, OSQL, etc) and especially the version of SQL Server (Express, Workgroup, Standard, Enterprise, Developer)

Any comments would help.

SQL Server 2012 :: Using DateDiff To Work As Excel Network Days

Jan 2, 2015

So I am trying to work out the difference between today's date (GETDATE()) and a Target Date in a specific table (targetdate)

When I use the DATEDIFF function it is including non working days in the calculation (weekends and bank holidays). Although our date calandar table provided to us from a third party supplier will tell you the weekends, it does not tell you the bank holidays.

Luckily there is another table in the database called - ih_non_work_days.

The format of the date is "2014-12-25 00:00:00.000" for example in that table.

How do I using my "targetdate" and today's date calculate in days the differance - excluding the dates that exist in the ih_non_work_days database?

So for now my basic script looks like -

SELECT com.comm_reference AS 'Referance'
,com.current_task_target_date AS 'TargetDate'
, DATEDIFF(D,com.current_task_target_date,GETDATE()) AS 'Incorrect Date Calculation'
FROM [dbo].[em_communication] as com

Remote Network Connection - Error 26

Nov 19, 2007



I am converting over from MSDE to SQL Express. My front end program is unable to connect to the database. To troubleshoot, from the remote computer I tried connecting with the management program and I get the Error 26 unable to connect.

Here is what I have done: I made sure that the SQL Server configuration has been changed to allow network connections (both TCP and named pipes). I have disable windows firewall on both machines. I confirmed that I can connect from the remote machined to the server by network browsing. Both machines are running XP Proff. There is no other security software running on either machine.


More Info. when attempting to log on I am using the server authntication, I use "sa" as the user id plus my password.

Goal. The front end of database program connects to the server remotely using a program called Hamachi over the internet. This works without a problem on MSDE. But for now I am simply try to connect using the managment program which lets you browse for other serves. When I do this it shows the remote computer, but not the name of the computer but not the SQL server which I type in like the following: "INTELsql1"

What I have not Done: I have not changed any permissions or added any users to the server, since this does not seem necessary. As stated the user of remote machine can connect to the server and change files.

Would appreciate any suggestions or tips. Thanks.

Need Novell Network Connection Without Logging On First

Apr 12, 2007

I am new to SSIS but this does not seem like it should be a hard thing to do. Here is the background:



Windows Server 2003

SQL Server 2005

SSIS

Logged in to server as Admin



I've created a SSIS package that I want to run as a Job. In it there is a Ole DB Connection to a VFP Database on a Novell Server. Client for Netware Services is started when server is but NOT logged into. When I created the package everything runs fine. Note that I had to login when I created the Data Link. I can even run it from the SQL Server Package Store. As soon as I restart the server and try to run it I get an error that the file path is invalid in both SSIS and the Package Store. I check the connection string and it looks good.



The connection is availible in My Network Places

If I open the connection and login it runs fine again.



How do I intiate the network connection and then close it again??

SQL Server 2005 Setup Of 2 Vista Machines, Can't Get Individual Network Login Accounts To Work On Each Others SQL Server

Apr 16, 2008


Hello all,

I have 2 networked PC's both running vista ultimate

1st is Laptop and is running its own SQL Server at laptoplaptopSQL
2nd is Desktop and is running its own SQL Server at desktopdesktopSQL

Now both machines have seperate windows login accounts.

When I go SQL Server management studio I go to browse and each machine can see the other machines SQL Server, but when I go to login I get SQL Login falied for users" The user is not associaed with a trusted SQL server connection".

So I then go to logins new login and try to add my other pc's user account.
The problem I see is that when I go to search and then location it only shows its own PC's location and not the location of my other networked pc? So if I am on Desktop and in my theory want to add laptopuser to the desktop SQL Server logins I get:

"create failed for login laptopuser

An exception occurred while executing Transact SQL statement laptopuser is not a valid windows NT name. give the complete name


Not sure on where to go from here.

Any help would be great

Is Replication Without Network Connection But File-based Possible?

May 9, 2006

Hello,

I've been looking around in several SQL-Forums and in SQL Books Online but haven't found clear suggestions how to tackle my problem:

Our company has to fill a database with documentation for our contractor. Our subcontractors have to supply information from their branch/craft into this database, too.

Replication (without determining a type at this time) would do fine for data-exchange between us and our subcontractors.

But for working in different companies the networks are not connected
and in some companies/departments connection to the Internet is prohibited at all.
This would result in data-exchange based on files - which wont be a problem as data needs to be updated/exchanged only once a week and is usually done at meetings using DVD-Rs.

scenario in short:
- two-way exchange of data between SQL servers being not connected
- update needed once a week
- our server: SQL Server 2005 Standard (preferred)
- servers of our subcontractors: SQL Server Express 2005 (preferred)

That's the point where I dont know how to proceed:
Is two-way replication based on files possible at all?

I read about Snapshots, but to my understanding this replaces the "whole database" without caring about changes made to it and that's why it wont work for two-way exchange.


I would appreciate your hints how to solve this problem in general or whether I should look out for other solutions - MS Access might work with restrictions - but I would prefer SQL Server.

Thanks for reading until here and in advance for your answers.


Regards,

It finishes most of the queries in the script, but on some (and not always the same tables) it gives the time out error. I am not quit sure where or how to research this problem.

Any ideas are welcome!
Thanks,
Michiel

Intermittent Connection Timeout / General Network Error

Nov 26, 2006

We have a SQL 2005
clustered server (Microsoft Cluster Services) that is queried from 4 IIS6
Windows Server 2003 frontends. Each frontend runs both classic ASP apps
connection with SQL Server ODBC and .NET2 apps connecting with
System.Data.SqlClient. Ocassionaly we get a string of errors/timeouts opening a
connection lasting maybe 2 minutes.

One the classic ASP
apps we log one of these two errors:

Microsoft OLE DB Provider for ODBC
Drivers (0x80004005)
[Microsoft][ODBC SQL Server
Driver][DBNETLIB]General network error. Check your network
documentation

or

Microsoft OLE DB Provider for
ODBC Drivers (0x80004005)
[Microsoft][ODBC SQL Server
Driver]Timeout expired
on the
ADODB.Connection.Open
On the .NET2 apps we
log
Message Timeout expired. The timeout
period elapsed prior to completion of the operation or the server is not
responding.

Flat File Connection - Network Share - SQL Agent - HELP!

Jun 19, 2007

SQL Agent will not successfully execute my package as a job. Bids executes the package correctly as well as when I run the package manually (right click, run package) through SQL Server Management Studio. This is a permissions issue with the flat file any help will be much appreciated.Background Information:OS: SQL 2005 on Windows Server 2003Flat File Connection: \servernamefolderfile.txt (If I change the flat file location to a local file the package will run as a job successfully)Domain: The package is running on a Windows machine that is not on any domain. The network location is a Windows machine on a domain.Security: The network location folder (\servernamefolderfile.txt) has no security, namely anyone can access any file to read/write/delete/etc. I can manually add and delete files as well as add and delete files when the package runs through BIDS or when I manually run it through management studio.Permissions: I have created a login, security credential, and proxy which I am using to run the package. The security credential is tied to the Administrator account on the local machine.
Error Message: Executed as user: COMPUTER-NAMEAdministrator. Microsoft (R) SQL Server Execute Package Utility Version 9.00.3042.00 for 32-bit Copyright (C) Microsoft Corp 1984-2005.

(note: I replaced the fileconnection strings with FILECONNECTION and the serverpath with "servernamefolder" for privacy reasons.
Any help would be greatly appreciated. This is some sort of security issue with SQL Agent. But, the error claims that the user is running as localmachineAdministrator. Isn't this how the package would run if I manually execute it?

Multi Connection To .sdf File Store On Network Share

Feb 22, 2007

Hi

In the "Choosing Between SQL Server 2005 Compact Edition and SQL Server 2005 Express Edition" white paper, i can read that: "SQL Server 2005 Compact Edition support data file storage on a network share" and "Number of concurrent connections = 256"

But when i try to connect with two different PC at the same time to a .sdf file store on a network share, i have an error message : "File is locked by an other processus"

The firsth PC is connected but the secondth can't

";Mode=Read Write" in the connection string don't change anything.

 An error has occurred while establishing a connection to the server.

General Network Error Even Good Connection And Small Amount Of Data

Nov 5, 2006

Hy everyone,

I have a problem at pulling data on PDA using Sql Mobile 5 from Sql Server 2000.

It work s for most tables, except for two . Every table of those two has about 1000 records and every record about 150 bytes, so all data is about 150 kbytes.

When I connect to the Sql Server 2000 through LAN, no problem. But when I connect through GPRS - VPN, the error occurs. But, the PDA- phone connection is via Bluetooth and at ping no TimeOut appears, the replies are about 600-700 ms. When connecting with a desktop computer through GPRS no such problem occurs.

So , I don't know what could be the cause: the connection or the Sql Mobile which doesn't retry enough in case of error to transfer all data .

A specialist from the GPRS provider told me to use 3G phone , but , because the GPRS phones have already been bought, this would be a too big investment. So, I don't think this is a good idea in this moment .

I found similar problem on the net and a solution was to use Pooling = False. But , in Sql Mobile there is no pulling parameter available when making the connection string .

Any help is very precious to me ,

Mihai .

Cannot Get Connection Pooling To Work

Jun 27, 2001

Hi everyone

I am using VB5 SP3 and ADO 2.5 to connect to SQL Server 7 SP2 and I'm trying to test connection pooling.

I open three ADO Connection objects as follows:

Set con = New Connection
con.Open "Provider=SQLOLEDB;Data Source=(local);Initial Catalog=pubs;User ID=sa;Password=;OLE DB Services=-1"

The second and third connections open virtually instantly, which seems to indicate that pooling is working, however, when I list processes in SQL Server it shows one process for each separate ADO connection. I thought the whole point of pooling was to make all these ADO connections map to the one physical connection and therefore one process. What is going on?

Just to make sure, I also tried it with RDO 2.0 and ODBC connection pooling and I get exactly the same results.

I'm very worried about this because it could result in our using up twenty or so SQL Server connection licences per workstation instead of one.

Database Connection Won't Work

Nov 11, 2007

I have read many tutorials and articles on how to connect with ADO.net and thought I had it right, but I don't so I'd appreciate any help and guidance you can give me.

This connection works:
Dim ConnString As SQLConnection
ConnString = ("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database1Names.mdf;Integrated Security=True;User Instance=True")

but this one does not work. Why doesn't it work?
Dim ConnString As SQLConnection
ConnString = ("Server=(local).SQLExpress; Database = Database1Names.mdf;Data Source = Trusted_Connection = True")
This code I copied from the tutorials I've read so I'm very confused why it won't work. the one that does work is nothing like this one!!
The first connection is the one I got from the property window of the dataset
I'm using XP Pro, VB.net express 2005 and SQL Express. I don't have any passwords on my laptop
As a beginner, what confuses me is that the tutorials I read say one thing, yet the code that works is completely different.
Any help will be greatly appreciated. Thanks
Regards,
Steve
