Domain Scanning Problems

Domain Scanning Problems

When running a domain scan with SD+ it works ok for most of our users, but a few it just doesn't. If I try and scan it manually it comes up:

FAILURE : User does not have the access privilages to perform this operation.


We are using the main Admin user name and password so this can't be true.

Also if I were to run the whole domain scan again, it wont add the existing computers again will it? So that there are duplicates?

Thanks in advance
