I'm having FRS & DNS problems after replacing a network card in a Win2000 BDC. Printing services drop and DNS quits working on the BDC intermittently. I know it's not called BDC anymore but you probably know what I mean. Reseting the server seems to band-aid the issue but then a few hours later the issue(s) starts up again. I've had this problem before but don't remember how I fixed it....I looked around on the Net and found some repadmin information...but that command failed as RPC seems to be breaking too. I opened AD Sites and Services and changed the replication protocol to IP, hopefully that will help things. Any suggestions or comments are appreciated. Thanks!
