The DHCP Service is dropping (sometimes twice a week) Any suggestions on why this could be? There is free space for the DHCP scope. IF not how is it possible too use alerter too notify someone when the service stops in the meantime?

What do you mean by dropping? Is the DHCP Server service stopping on the DHCP server? Are the clients not being issued with an IP Address? Can you manually get an address (ipconfig /release, ipconfig /renew). Are the clients on the same subnet or using DHCP routers/Broadcast routers?

A spot more information and I can probably help.

JB.

The DHCP service stops and someone has too physically restart from the "Services" control window on the PDC NT Server. No clients can log on because it's not running there are no routers and only about 60 machines attached on the one subnet. Sorry I wasn't more specific.

Did you apply the latest service pack? On NT 4.0 it is SP6a.
I remember DHCP giving me trouble at times when NT 4.0 SP3 was current.

You may try to repair your dhcp.mdb database.
Stop the DHCP service.
Open command prompt.
Go to WINNT\System32\dhcp directory
run command:
jetpack dhcp.mdb zzdhcp.mdb
(zzdhcp.mdb is temporary file).

If repairing doesn't work and your network is not too big, you may try to delete dhcp.mdb and recreate your dhcp configuration. Before doing this, set lease duration to some 10 minutes to avoid IP address clashes when your DHCP service comes back alive.
