Trying to configure the ODBC DSN (using IBM DB2 ODBC Driver v 9.05.00.808) to connect an IIS Crystal Reports report to a DB2 database. The server is a Windows 2003 Standard x64 with IIS 6.0 installed fully patched. DB2 is v8.1 (or 8.5) running on Linux.

We configure the DSN and test it and it says it Connected Successfully (both as x32 and x64 bit) BUT we get the following error in the Application Log:

The description for Event ID ( 4 ) in Source ( DB2 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event:
2009-04-03-07.42.26.186000   Instance:DB2   Node:000
PID:3316(odbcad32.exe)   TID:3604   Appid:none
RAS/PD component  pdLogInternal Probe:20

ADM14000E  DB2 is unable to open diagnostic log file
"C:\PROGRA~1\IBM\IBMDAT~1\db2\db2diag.log".  Run the command "db2diag -rc %s"
to find out more.

We have been unalbe to locate this "db2diag" program anywhere so this is all we get.

Since the test ran fine in the ODBC Administrator, we tried running our reporting tool in IIS and get the same error message again AND it cause a lock up in IIS where the application pool has to be restarted after you KILL the PID for that service.

This is only my second time using ODBC stuff but first time I'm having to connect to a DB2 database. Any assistance in either websites, online books, or just thoughts would be appreciated.  OH please don't send me to IBMs site either unless you know its 100% workable. I've spent the last 2 days combing the beast and I've pretty much given up on them.

We've found the fix. It was two problems. First, the major one was that fact that the DB2 driver only wanted to use the 32 bit driver. The servers are configured for 64 bit only. Reconfigured the IIS to support 32 bit apps to run on the 64 bit IIS.
Second problem was an issue with the DB2 driver. The developer and I had the same version loaded but when you compared the db2cli.dll files, They were not the same size or date. Once I loaded the same driver the and configured it, the app worked perfectly.
