Hi Folks I have a situation that is causing me some problems. I have a number of services ending unexpectedly on my MS Exchange Server. Windows 2000, SP3, Exchange 2000 Std, SP3 The services failing are IIS Admin Service MS Exchange IMAP4 Service FTP Publishing service NNTP Service MS Exchange POP3 MS Exchange Routing Engine Service SMTP Service WWW Publishing Service service All these services end unexpectedly at the same time and sometimes come back up and sometimes I have to reboot to server to get them up. When the services go down the outlook client’s crash and given that I run citrix for about 90 users on 3 citrix servers …it is also causing performance problem there. I am running Symantec AV 8.1 and SAV for Exchange 4.0. The error log message is common for all these service terminations.
