Win 2003 DHCP Problem

Hello,



We are at the beginning of converting our school system from Netware 6 with
servers in every building to centralized 2003 server forest. We have
recently had Fiber installed between 3 of the buildings with others to
follow over the summer. With this fiber we have moved for Netware DHCP to
2003 Server DHCP. 2 of the 3 buildings have worked fine, but the High School
has a problem with the old Windows 98 Machine randomly dropping the gateway
address. Some time these machines will hold for a day other times only for
about 15 Minutes. This problem is not happening in the other 2 buildings and
is not affecting the XP Pro Machines.



On these machine we have tried all of the following, moving hub/switch
locations, changing NIC cards, completely reloading machines from scratch.
And none of these have worked. We have the same machines, NICS and loads in
the other 2 buildings and they work fine. We have also checked all the DHCP
scope settings to see that they match.



We only need a fix to get us thru the next 5 weeks as we will be completely
changing all the machines to new dells with XP Pro after the school year is
out.



Any Ideas on what to do to fix this?



Thanks in Advance

Greg Bemis

Win98 has problems with DHCP sometimes. I've had one that would not accept
anything from DHCP for no reason at all.

Just manually configure the Gateway fo the time being. You can manually set
the gateway while still getting the rest from DHCP and it won't hurt
anything. Witht he one I had, I just statically configured the machine and
left it that way till it was replaced later.

Thanks for yor response. I have already tried to hardcode in the gateway in
tcp/ip settings in the Windows 98 machines that we are speaking of and it
still will drop the gatway. When this happens the machines still have the
leased IP address and the correct mask and the date that the lease is
obtained is the same so it doesn't look as though the machine or the DHCP
server is doinganytype of renew. We can also reboot the machine or wipipcfg
release/renew and the gateway comes back. Trouble is that you lose the
Netware drive connections if you use winipcfg to release/renew, so that
leaves you with rebooting the machine and these are P2,P3 266-350 machines
that take several minutes to reboot. So if is dropping the gateway several
times an hour this is a big problem.

Any other Ideas??

Just make the whole machine static and forget it. Don't give it an address
that is given out by DHCP. Make sure it is an Excluded Address. It isn't
worth fighting with on a 98 machine that will be replaced later anyway.
