DC can't see workstation, but workstation can see DC....

[Andrew Connell]

I have a Win2003 server setup as my AD DC and a WinXP Pro SP1
workstation joined to the domain. I had two working roaming profiles
and everything was working flawlessly

I decided to rebuild the workstation after some significant HW
upgrades (MB, CPU, MEM, video card). I've been able to successfully
re-join the domain, but it appears I'm having some networking issues.
Before/after joining the domain, the workstation can resolve the name
of the DC and ping it. However, the DC can't ping the workstation
(even though it does resolve... but I don't know if this is old data
as the rebuilt machine assumed the same IP [I'm using DHCP]). You can
tell there are networking issues because sometimes when one of the
roaming users logs in, it never finishes D/L the profile (same deal
when logging off).

Any ideas of stuff I can look into? Both are in the same subnet and
have the same gateway. I've verified the workstation is obtaining the
correct networking config from the DHCP server using a XP laptop that
is in the domain and working.

On my way into work, I thought of something...

I'm not using the same NIC as I was before (new motherboard has an onboard
NIC which I'm now using). I need to double check and make sure the MAC
address in the DHCP table matches the new NIC... not sure if that would
affect it.

Also thought about forcing it to take a different IP. Here's my config FYI:

DC: 192.168.0.100 (subnet) 255.255.255.0 (gateway) 192.168.0.1
XP: 192.168.0.5 / 255.255.255.0 / 192.168.0.1 (DNS) 192.168.0.100 (secondary
is my ISP's DNS)

I'm using a DSL gateway hub as my DHCP server/router/hub.

Doh! The most obvious... Thanks, I'll do it when I get home.

I installed all software before joining the domain... including McAfee's
Firewall. There's a place to tell it to "trust everything on my LAN"...
least I know I need to add my two other machines on my LAN by IP.

Unfortunately that didn't fix the problem... well I can now ping both ways
and my firewall doesn't show anymore entries in the event log. I can easly
connect and pull/push files from desktop to server & vice versa with no
problems.

Everything works great on my laptop with the roaming profiles, but the new
XP install on my desktop just takes forever (I let it run for 45+minutes
tonight) to pull the profile across... even watched the switch to see no
activity on the desktop (but the laptop has tons of activity when logging in
under the exact same profile).

I've setup the profiles as local profiles and I'm staying clear of using my
laptop on some profile areas (email, desktop, mydocs, myprojects, etc) until
I figure this out. I did see something in the Event Log... a warning for
"Windows has detected that Offline Caching is enabled on the Roaming Profile
share"... but it's on both the desktop and laptop (again, laptop has no
problems and runs the same OS with the same hotfixes installed).

Any ideas/assistance would be greatly appreciated.
