After applying service pack 7 my dhcpsrvr.nlm was update to version 3.13c
I am now experiencing a problem which has been described in other threads.

If a Manual IP address is assigned then the options don't seem to be
updating correctly. Machine is windows 2000. The problem is strange as
an ipconfig /all shows no gateway and then if you run it again right away
it show a gateway but no DNS servers.

I backreved to my trustee 3.11a version (which I had to backrev to for a
previous 3.12 problem with manual ip addresses) and everything now works
fine with the manual address.

Is this a known bug? I don't have a service contract, can I report the
bug in some other way than opening an incident?
