Recently, we upgraded our NT domain to 2003 with Active Directory and DNS. We are currently running in mixed-mode. To start with, we had problems with Win2k PC's wouldn't join the domain - but rejoining the domain by joining <ourdomain>.domain seemed to have cured the problem. We also had problems with Win95 PC's needing the Active Directory fix.
We seem to now have a problem with authentication. If i'm logged in as a domain admin, and try browsing to a c$ of a Win9x PC, it will ask for a password (which we put in and it says its wrong - even though we know its right). The PC's are logged onto the domain ok (we can see them when we browse the domain), and people can access any network location they need to. This is also affecting our remote control software (which is a right pain in the a** when we're trying to support 300+ win9x PC's!). Applying the AD fix from microsoft has made no difference.
Is there a setting on AD that could cause this or have any suggestions as to things that need checking?
It has us all stumped here, and even other 3rd party companies have no idea..
