I have a client running SL 2011 with many screens developed using the SL SDK. Until today, all of those custom screens were working fine. Now, today, every one of them is giving the following error (no matter from what workstation they are launched)
System Message 10232
Assertion failure
File: sqlodbc.cpp
Line 9672
When these same screens are run directly on the SL server they run just fine. All the standard SL screens open just fine from the failing workstations.
I ran into this one time before and it was related to a Windows Firewall setting that was not allowing outside SQL requests through but, in this case, the Firewall settings do allow sqlservr.exe through and, as I said, the standard SL screens are working. I tried to temporarily turn off the Firewall but that did not make a difference. The user and their IT people claim that no changes to the workstations or the server were made yesterday but, obviously, something changed.
So, my first question is if anyone has run into this before and found the cause. Remember the standard SL screens are working, the custom screens were working up to day and work on the server and no changes have been made to the custom screens.
My second question is whether anyone knows why screens developed using the SDK work differently, in some fashion, from Microsoft developed SL screens?
