I am getting ready to switch from a domain running Active Directory on a Windows 2000 server to a new domain that will use an SBS 2003 server for the DC. The old server will be phased out. We are on a network of about 30 computers. The SBS server was running fine on it's own domain until I installed some ERP software that seems to make it freeze from time to time. Mouse moves but desktop is gone and it can't be seen on the network. I uninstalled the software to no avail. since it is not critical YET. What would be the best thing to do. Even if I have to reinstall I an do that. Are they any problems with that?
