I am having problems with several windows xp pc's. The first sign of a problem was when people logged in and opened outlook 2003, they received a message stating that Word 2003 is the default email editor but it was not the same version. We tried to reinstall word 2003 and received a message that Windows installer could not be accessed, access is denied. This started to happen to all pc's on the domain. Upon further investigation, I noticed that 1 of my 2 Windows 2003 DC's had event's 1030 and 1058. I have since read about 100 KB articles, forum post and everything that I can find and still can't resolve these issues. One more thing, we were trying to install Symantec Mail security the day before this all happened on our relay box in our dmz. We needed to give the back end servers IWAM account impersonation rights. I have sinced removed this hoping it would fix the problem but it has not. This is a real nuisance and becoming a real big problem. Any Ideas?
