I have an NT Server 4.0 running DHCP for all my clients - ocassionaly in the DHCP manager I get a BAD ADDRESS or just a blank client name. It shows the IP address and no client name or just BAD ADDRESS as the name. I delete them, but the continue to come back. How can I resolve this? Any suggestions are appreciated - I'm not really familar w/ DHCP, but it seems to be working good for all the client machines. Thanks!!!
