Make sure you created the dsn on your win2k3 machine too.

You can also checkout the DSNLess trick. This page would help you out with one:

lets see ur connection string.......

 

by: nurv-xPosted on 2005-10-31 at 06:47:43ID: 15192893

here's the connection



<%
Set dbConn = Server.CreateObject("ADODB.Connection")  
dbConn.Open "dsn=insertnamehere"
strSQL = "SELECT TOP 1 ID,NewsImage,Headline,left(NewsBody,200) as TrimmedBody,ImgAlign FROM qrynews"
Set rs = dbConn.Execute(strSQL)
Do While Not rs.EOF
%>

 

by: REA_ANDREWPosted on 2005-10-31 at 06:48:50ID: 15192902

Yes i agree would be good to see the connection string.

 

by: chris_smith_51Posted on 2005-10-31 at 06:55:21ID: 15192968

Try this:

<%
Dim dbConn
Set dbConn = Server.CreateObject("ADODB.Connection")
dbConn.ConnectionString = "DSN=NAME OF DSN.dsn"
dbConn.Open
%>

Check ur dsn is set u ok:

1) Start>Settings>Control Panel>Admin Tools>Data Sources(ODBC)
2) Go to system DSN tab.
3) Check your dsn is listed, if not create a new one with the mdb driver
4) Make sure your Data Source Name is the one used in the connection string (i.e. where it says data source name type in the name of the dsn and also type in ".dsn" after it)
5) Select the DB you want to connect to
6) Click okay and you should see it in the list, try accessing again with the new connection script

even if ur dsn does exists - try removing it and recreating it. it doesnt take long to do and may fix ur probs!

 

by: nurv-xPosted on 2005-10-31 at 07:02:36ID: 15193024

I've already tried recreating it. Permissions are set as well.

Sorry fellas.
Thanks for your assistance in this matter but the issue has been resolved.
I did a few more searches in EE and found a solution that fixed my issue.

Someone else had a problem where all of a sudden their ODBC wouldn't work but their's was complteley gone when they upgraded from Windows2000 Server to Windows2003 Server. So someone suggested to them to reinstall the reg key.

When I browsed to my ODBC reg key I noticed there were no values.

I had soemone send me their regkey from their Windows 2003 Server machine and it fixed my issue.

 

by: hongjunPosted on 2005-10-31 at 20:09:52ID: 15198205

It would be nice if you could post the solution here.

 

by: nurv-xPosted on 2005-10-31 at 20:11:02ID: 15198208

uhm read above?

 

by: hongjunPosted on 2005-10-31 at 21:27:44ID: 15198388

Ya.. I am referring to the registry values.

 

by: nurv-xPosted on 2005-11-01 at 08:13:50ID: 15201053

Ok.

In detail here.

He opened his registry and browsed to HKLM/software/ODBC. He then right-clicked and exported the registry folder to his desktop and emailed it to me. I then double-clicked the file to install it onto my server.

I am kinda having the same issue.  A user rebooted our 2003 Server, now some of our applications will not work, and we receive the NO DEFAULT DRIVER ERROR.  I am going import the ODBC from another server and see what happens.
