I run NT 4.0 workstations and have uninstalled IM under the administrator account. I have even have traced some registry keys to remove IM's presence, but every time the user logs in there is an error stating the OS cannot find C:Program... which is the IM program. How do I completely remove every reference from the users' side?
systemrootprofilesusernameStart MenuProgramsStartup directory for each and every user profile.
Make sure you do the same for:
All Users and Default User.
In the registry, check:
HKLMSoftwareMicrosoftWindowsCurrentVersionRun, as well as RunOnce and RunOnceEx.
If you have any legacy 16-bit programs installed on your workstations that may have installed their own .ini files, you can also run a FindFiles for "*.ini" containing a reference to the .exe in question. You can do the same running a FindFiles for "*.*" containing that reference, but you will find many more files, most of which will not be relevant to your search.
