We are migrating to a Windows 2000 Server and have set up a Domain Controller and are using Active Directory. So far all of the security settings in the Domain are default. When logged on as a user and trying to perform an install on a client computer (Windows 2000 Pro) using the "run as" option and of course using admin credentials, the install will seem to complete successfuly but will fail in the end. This is happening with various different programs. I always have to log off the domain and log on as a local administrator to complete installs. It seems like there are certain processes that are being stopped when logged into the domain. I have set up the same scenario at home and the exact same problem exist. I sure would appreciate your comments. Also, not so important, but when logging the user back onto the DC I have to reset the default printer. This is very annoying.
