All, I apologize for continuing the off topic
posts. However, I think this may be a good place to get an
answer.
I'm getting a very perplexing problem with
Exchange 2000 SP3, Win2K SP3 and WLBS. We have 2 front end servers and 3 back
end servers. For about a half hour, we were able to get them working no
problem. The front ends each have 2 NICs, one for direct connection (unique
IP) and one for WLBS (shared IP w/ load balancing). WLBS on each server is
setup as follows with the shared IP as the only IP running on its adapter. In
addition, the host headers on the Exchange Virtual Server are set up with the
DNS name of the WLBS.
It originally worked like a charm and then after
about a half hour, the servers had connectivity problems. It's a pre-staging
lab so I restarted the machines. Then the System Attendant wouldn't start.
Even if done manually. I was getting 2102 errors saying that the server
couldn't communicate with the global catalog (pre-stage lab has one DC which
is a GC). 2 Backend clusters (running MS cluster service) could communicate
fine. Everyone could ping everyone, even the problem servers. The load
balanced IP was registered in DNS and WINS correctly.
I disabled the adapters that were running WLBS
and rebooted the machines. Exchange came up like a charm. No
problems.
I reenabled them again and rebooted. Same
problems.
Does anyone have any suggestions? I'm open and
tapped out of ideas.
Thank you,
Marc
