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!!!

Do you have networked printers?  Often other devices will request addresses and not provide client names. What NT service pack are you running... applying SP6 (or re-applying) can help.  Try this for more info on bad addresses:

one the point from posivibe netowkr printers such as netports seem from my experience to work better statically assigned and excluded from the scope. Do you have any non windows DHCP clients other than printers?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

These are the only things in my event log.

EVENT ID: 1011
The DHCP server issued a NACK to the client
(0064A8C0015241532002BFD8CBBA93000002000000)
for the address (xxx.xxx.xxx.xxx) request.

EVENT ID: 1012
The DHCP Client (0064A8C00100A0D4205364)
declined the address (xxx.xxx.xxx.xxx).

All my printers have dedicated IPs, except for a few that use DCHP - but those I can see as hardware name references.

It happens, and there is not much that can be done. If you have sufficient addresses, it should not make any difference as the lease ends and the IP is reused. It is only a problem if you are really short of IP's.
I hope this helps !

Disable the RAS services in the affected client machines & see.  Generally this takes more than one IP & this creates the BAD Address problem.
