I have posted a similar question to this before and i am having the same problem, here it is...
If i install windows xp onto a new client machine, login as the administrator and install all the necessary apps and things that he may need, all works fine.
After all that, i grant that user admin rights to his pc creating his name with admin. priv to the local machine..
I then logoff and login with his name and all seems to be fine. If i click on a specific app it gives me and error or a series of errors, but when i hold in shit and right click, i select "ran as" type in the domain account "administrator" and password then it runs fine.
I cannot give the users that password "what could be wrong?" I have a system policy in place which prevents the users from installing/removing apps and playing with settings, could this be that cause, what can i do to correct it?
