I think I may have totally screwed up my network. I have a windows 2000 server with 13 workstations. I installed active directory and everything was working smoothly. I then got broadband and ended up having router problems. I ended up switching my serve's ip address from 1.251 subnet to 0.251 to get to the router...like a moron. Well anyway...as soon as that happened I came back to 1.251 and all sorts of authentication problems started hapenning. I don't know what's going on...can anyone help?
