sql server msde : Can not conenct to MSDE with VB.NET 2003
First i appoligize for my english but I'm from Belgium Second, this is my problem: I installed a Server on my Server PC (Windows XP Professional) setup SAPWD="mypwd" INSTANCENAME="MSDESERVER" DISABLENETWORKPROTOCOLS=0 SECURITYMODE="SQL" TARGETDIR="C:\MSDEINSTALL" /L*v C:\MSDELOG.TXT + Enter Works perfect, then I attached a database to it osql -E -S peter-developer\VA3+ ENTER EXEC sp_attach_db @dbname='VA2005',@filename1='C:\test\VA2005.mdf', @filename2='C:\test\VA2005_LOG.ldf' + ENTER This works, and in vb.net i can connect to it with "Data Source=PETER-DEVELOPER\va3;Initial Catalog=VA2005;Integrated Security=SSPI;" But when i try this from i remote PC (Windows XP) I get an error that says: SQL server does not exist or access is denied I searched almost everywhere and i can't find the answer. EXTRA information With svrnetcn.exe a set Named pipes, TCP/IP and NWLINK IPX/SPX to enabled I put the firewall of, and the firewal of the router is off Please help me
I'm confused.
In the setup, you indicate that the instance name is: "MSDESERVER", yet in the connection string you are connecting to: "PETER-DEVELOPER\va3". Do you have a second instance named [va3]? Shouldn't you use the instancename [MSDESERVER] in the connection string if you want to connect to that instance? -- Arnie Rowland, Ph.D. Westwood Consulting, Inc Most good judgment comes from experience.

How do you connect the MSDE from the remote computer? Via an application
with the same ConnectionString as you showed? If yes, that means you are using Windows security to connect to the MSDE. Is the remote computer on the same domain network or peer-to-peer network? If it is domain network, you need to have a SQL Server login created in MSDE that maps to the domain user account used on that remote computer, or the user logged on to that remote computer is a domain admin. Since your MSDE's SQL Server security is enabled, you could specify user name and password in the ConnectionString (i.e. using SQL Server security, instead of Windows security). More important thing is to do a bit more study on SQL Server/MSDE security.

hi,

[quoted text, click to view] > .... > Doesn't work ether > > You say something about making a new user, I don't understand that, > could you explain it again please when you try a remote WindowsNT authenticated connection without the presence of a Domain Controller, the remote sid corresponding to the remote account is passed, so credentials for OtherPC\AccountName is remoted... obviously SQL Server can not validate these credentials and the connection will be refused... a dirty workaround is to create, on the SQL Server box, the very same account (with the very same pwd) of the "remote" user... so you can create the PETER-DEVELOPER\AccountName ... when connecting from the remote pc, a sort of netbios inpersonation is performed as a local same account exists on the SQL Server box... this is not granted to works in the future, as future OS or even service packs for present OSs can (hopefully) modify this behaviour... in workgroup scenarios, the best method is to use standard SQL Server authentication.. -- Andrea Montanari (Microsoft MVP - SQL Server) http://www.asql.biz http://italy.mvps.org DbaMgr2k ver 0.20.0 - DbaMgr ver 0.64.0 and further SQL Tools --------- remove DMO to reply

The 2 computers are in the same worgroup, and when i typ \\peter-developer I see the server PC and I can get files from it or drop files on the PC. I want to connect to the VA3 server with a VB.NET 2003 application and i do it with following connection string "Data Source=PETER-DEVELOPER\va3;Initial Catalog=VA2005;Integrated Security=SSPI;" Doesn't work "Data Source=PETER-DEVELOPER\va3;Initial Catalog=VA2005;Integrated Security=SSPI;User ID=sa; Password=pass" Doesn't work "Data Source=PETER-DEVELOPER\va3,1433;Initial Catalog=VA2005;Integrated Security=SSPI;User ID=sa; Password=pass" Doesn't work "Data Source=Peter-developer\VA3,1433;Network Library=DBMSSOCN;Integrated Security=SSPI;Initial Catalog=VA2005;User ID=peter;Password=peter" Doesn't work ether You say something about making a new user, I don't understand that, could you explain it again please
You do not need to combine both "Integrated Security=SSPI" AND "User ID=sa;
Password=pass". It is EITHER "Integrated Security=SSPI" OR "User ID=sa; Password=pass". -- Arnie Rowland, Ph.D. Westwood Consulting, Inc Most good judgment comes from experience.
