2 scopes, 1 superscope, 1st scope works 2nd does not

[studio1129]

Hello
Nt4 domain...DHCP on win2k member server..no dns...using wins
2 scopes 10.104.64.1 thru 254
10.104.65.1 thru 254
both in superscope
1st scope passes out addresss..2nd does not
only router used is for access to internet, it is configured with 10.104.64.1 and 10.104.65.1
switching handled by cabletron 6000

I can hardcode an address for the 65 segment and able to log in but everything is terribly slow..printers ect.
also login script (kixstart to bat) will not run
however I can see the whole network thru explorer and browsing is pretty snappy.

a tracert to the PDC on 10.104.64.21 is very slow...however a tracert to another machine hardcoded to 10.104.65.60
is very fast.

Any ideas? or do I need to probide more information?

Regards
Rick Strickland

Have you checked your logs for errors on the bad machine?

Is the router configured to forward UDP from the .65 network to the DHCP server?

DHCP client/server communication uses UDP broadcasts to talk, if there is a router in the way, its not going to forward those broadcasts to your DHCP server unless its been told to. Most router docs will refer to this as a UDP helper.

Thanks for the help Folks!
Problem solved... This was a strange one...

The port on our Cabletron 6000 switch receiving the
feed from the gateway was set for 10 mbit/half duplex
Our NEW router for our gateway was set for 100/full duplex.
(the feed leaves the gateway..goes to a hub..then to the switch)The hub is where it is in the system to run a sniffer on the network. Really slows things down.

This situation absolutely wreaked havoc with our network.
One of those times when what seemed like the problem (DHCP)was really just a sympton of another problem (misconfiguration of the router).

I manage a small gov't network that is part of a large government WAN. The gateway and the router are not something I have access to and is handled by another contract a thousand miles away...and with all the security issues today...well it is hard to sometimes get all the information you need to troubleshoot.

Hope I explained it well enough here so someone in the future may benefit by this post.
