So this was a weird one.
I was installing a law firm case management program for a client (no names, but rhymes with “Babacus”), and during the install a reboot was required. At the time, everything seemed to be working correctly, and I continued on my merry way. However, a couple of hours later, I got a call saying that Blackberries were not receiving emails, and that Outlook Web Access (OWA) was not available. I tried to connect to OWA, and received this error after login:
503 Service Unavailable
I then looked at the Blackberry Enterprise Server (BES) services, and they were all down, as was Backup Exec. The BES services, when trying to restart them, would give a “service-specific error code 5003”. After searching for the Blackberry error code to no avail, as well as multiple other sites to try to fix the OWA and other errors, I resorted to calling MS Support.
Which was supposed to call me back within 2 hours.
Which called me back almost 5 hours after my initial call (and after two calls to them for an update).
After spending some quality time with the tech, we finally boiled it down to a set of .dll files in Drive:Program FilesCommon FilesSystemOle DB. After trying to re-register the .dll files, one (oledb32.dll) would refuse to register with this error:
LoadLibrary(“oledb32.dll”) failed – The Specified procedure could not be found.
This included following KB 838176, which didn’t really apply, but was all about moving a clean copy of the .dll to both the target directory and the .dll cache. No joy. We even reinstalled Exchange SP2 on the machine.
What finally fixed it was re-installing Windows 2003 SP 2 on the machine. After a reboot, all was sunshine and lollypops. OWA, BES and BackupExec all started up and ran without complaint.
Yay!
