Hey guys. I have a customer that I upgraded to Service Pack 2 for Exchange 2003 last week. At the time, I didn't know they were running Sybari Antigen and that you have to disconnect Antigen from the information store BEFORE installing. Thus, I ran the service pack install without unmounting Antigen. Well, all worked fine and dandy for about 4 days afterwords, then the information store service started locking up. The only way to get it back, is to disable the service, reboot, uninstall Antigen, then restart the service. As long as Antigen is uninstalled, Exchange works like a champ. With it on, it's totally hosed. Unfortunately, there was no information in the release notes for Service Pack 2 about this. Anyone seen this before? Any ideas? I can find NOTHING about this on Sybari's or MS's website.
Thanks in advance for your help.
