Hi, I am getting the following errors in my E2K SERVER WITH SP-3. There are no issues with the mails, but these events messages really concern me. TechNet advises to apply the Service pack. Is it right thing to do? Please advice. Thanks......Suresh Event Type: Error Event Source: MSExchangeFBPublish Event Category: General Event ID: 8197 Date: 12/11/2003 Time: 13:45:50 User: N/A Computer: MAILSERVER Description: Error initializing session for virtual machine MAILSERVER.
