This is a wilde shot, but maybe someone who understand how this works has some idea where to start to lool
Server 2003 64 Bit. We have a custom made application that is used all over the world. To add user the program calls NT API (program made in delphi) and a little windows opens where we can add users to the application. The window shows all users currently in Active Directory.
We have used this on over 30 servers for over 5 years. Only 1 server has the problem.
ITs a very remote server in Africa, so no option to just reinstall OS in the forcomming future.
I can tell that a person has been messing around with this server but we have no idea what he has done (he for sure did not know himself)
The only additional strange thing i can see is that "regiedit" is giving an error "Your administrator has blocked this application"
I have checked the GPO for Domain and the setting was not configured, witch mean it should work. Admin not member of other GPO only Domain Default GPO. If i disable the setting in GPO it works for Admin. I have not had to do this on the other server. Maybe if i find the root to this, I will find the fault. Maybe not.
Can anyone who understand how this works, give some idea how to progress my trouble shooting?
