Our Exchange server feezes up for the 4 consequtive weekends. We did a lot work in the last weekend to get our exchange to the better stage : run all the firmware updates, bios.... However, the system failed to perform the defrag and generated the following error:defrag failed
- Callback DLL not found: Unable to find the callback library jcb.dll (or one of its dependencies). Copy in the file and hit OK to retry
- Operation terminated with error -2102 (JET_errCallbackNotResolve
d, A callback function could not be found) after 3353.16 seconds.
- followed http://www.tech-archive.net/Archive/Exchange/microsoft.public.exchange.admin/2007-10/msg00576.html
Any help in regards to narrowing down to the root cause would be respected.
