Hmm.. if you're using a function like mssql_error or something like that, it's 
likely coming from the driver and not php.. 

Did you see this on the docs page?

I have spent the last 2 days trying to get PHP to connect to MSDE on Windows 
2003 Web Edition.
 Although initally PHP would connect to the database without a problem, it 
would then refuse to connect, hitting F5 enough times would eventually 
connect to the database. As you can imagine this intermittent problem was 
hard to trace.
 I was using PHP 5.0.5 (although 5.0.4 has the same problem) on a Windows 2003 
Web Edition SP1 server, and was trying to connect to MSDE Rel A.
 Firstly MSDE needed to be installed with the following arguments: 
 Secondly it was necessary to delete ntwdblib.dll from c:\php
 Thirdly I downloaded the SQL 2000 evaluation and installed only the client 
tools on a seperate PC (Ent. Manager will now connect to the database).
 Lastly I copied the version of ntwdblib.dll from the PC with Ent. Manager on 
it (ver 2000.80.2039.0) to c:\windows\system32\
 After a re-boot no more connection problems.
 Pls note that this is only for 2003 Web Edition with MSDE, this problem does 
not seem to occour with Standard Edition
