I was having trouble adding users to my Exchange Server 2003 the other day when I never have any issues with this server (other than it not being able to install the Auto Accept Agent for some reason that Microsoft has been unable to figure out).When I looked in the Services listing I noticed the Remote Registry Service was not running and when I tried to activate it it said the file was missing. Sure enough the regsvc.exe file is gone from where it should be.How could this have been deleted? I am current on Trend Anti-Virus and have no PCs on my network (all Mac OS X) other than an Windows Server 2003 AD server which is also up to date with Trend AV, and have no other problems. I surely never monkey with anything on this server, especially not in system files!Can I just copy the regsvc.exe file from my AD server since it's the same version and paste it into the proper location on my Exchange server?Thanks
