Exch 5.5, SP4 + MS01-41 (emsmta.exe 5.5.2654.50)
After a while, the MTA stops logging any and all events to the event logs.
Increasing diag logging also logs no events to the log. It's functioning
fine, just not logging anything.
I've seen it on a few servers now. I can't say for sure that this started
after the hotfix installation.
Has anyone noticed this behavior? Or worked with MS on it? Seen any KBs?
