We have a Windows Server 2003 machine and Windows XP Pro clients. We have two domains 1 for staff and 1 for kids. We have one DHCP server which sits on the staff domain which releases ip addresses to both domains. The first DNS entry within the dhcp server is the staff one. So therefore when the kids login and we look at the network settings we find that the 1st dns entry is the staff domain, then it is the kids domain then it is the external dns (ISP). The login time lately is really slow 15 mins max to login to the network. It just says on Loading profile, applyng policy etc....
We have two servers on the kids domain, but while all the 6 computer rooms are being used the performance on the first of the kids domain servers is 100% for both disk and the paging file. On the first server we have the printer queues installed and the home directories for the kids.
