Belated thanks for those of you who offered advice on an issue last week. Using Exchange Standard 2000 sp3 on W2k Sp4 server. Question regarding the various services and the Log On As account. 1. Are there any other services related to Exchange other than those named Microsoft Exchange **** ? 2. Reason I ask: all of those use the Log On As account of "LocalSystem". I had created a user account to Log On and run my SQL services for better security, and was curious about doing the same for Exhange. Anyone do that, and if so, what rights would that account require? Thanks a lot.
