Hello all I am hoping you can help me. I have just migrated from
Netware DHCP to Windows 2003 DHCP. We are one of the departments in a
county that need some access to resources in the Main Downtown Office
- Timesheet and Fiscal stuff - but for the most part we host all of
our own services. This system has been in place for 2 or 3 years and
works good until the migration of DHCP services this last Friday. All
of our stuff locally works great and the server gives all of the IP
info we need however we cannot load web based apps that connect to to
our downtown office anymore. What is wierd is if I go to some of the
problem PCs and type in the TCPIP info manually, I can get to the apps
we need just fine, it is only when we allow those PCs to accept the
DHCP address that nothing works. We use DNS Forwarding for the
downtown domain, and I also have to push their WINs serves addresses
form our DHCP server to have everything work, but as I said this
system has been working great until the DHCP migration. I can ping
all of the servers both by name and IP, we need on their system only
if I type the TCPIP information manually on any PC on our network, if
we allow DHCP to give the same TCPIP information we cannot ping them
at all. I think I am missing a piece of the puzzle but am not sure
what it is and was hoping you all could help us put our finger on it.

Thanks in advance

We use DNS Forwarding for the
> downtown domain, a

By this do you mean that the new DHCP server that you set up is configured
to forward requests to the downtown domain?
Can you ping the downtown domain DNS server from your new DNS server?

I just have a new DHCP server our DNS server has been in place for a
long time and it forwards requests that need resources on the Main
County Office Domain as needed. I can ping that particular DNS/WINS
server from both our new DHCP server and DNS server. Just not the
client PCs getting the new DHCP addresses.

When using DHCP, I suspect your default gateway is not right. Typo maybe ?

Re: Windows 2003 DHCP Server

Well here is where I am at, I have all of the scope options defined
including gateway, I tried them as server options and as scope options
this did not work. I have tried disabling the firewall on the PCs
this also did not work. I spent 6 hours on the phone with Microsoft
and still nothing. I am now working with our Cisco guys - we have a
contract for all of our Cisco work - to see what could be blocking the
traffic. They do not think anything is blocked but are still
checking. For now I have assigned the old range of IPs that the
original Netware server was passing out and seems like everything is
working again. Something has got to be blocking traffic somewhere
just not sure where yet.

I appreciate all of the comments this is a strange problem
