Just the one. What's a "CARP problem?"

Actually, we still have an ISA 2006 server that handles all of our Exchange 
traffic and nothing else. If that makes any difference.

Thanks,
Rob

How many TMG do you have?
This "smells like" a potential CARP problem.

Hi List-

I have a curious problem. Let's see if anyone can come up with an explanation 
or a way to approach the problem.

Our archivist has a website where he stores digitized documents. It's off site. 
Accessing the server works great from his house-no errors, very fast, digitized 
documents load in less than 5 seconds. Same thing from my house. Same thing 
from a separate network in our building here, that uses our router but does not 
use our firewall. (It uses a much simpler firewall.) However, when we try to 
access the site from here, behind our TMG server (Standard), the site starts 
acting quirky. We frequently get dumped out with an odd error from the web site 
(I can send along a screenshot if that will help and is allowed on this list; 
the text is too long to type in) and when we finally do get through, loading a 
digitized document takes 30 seconds to one minute.

I've tried monitoring the connection using TMG. There are no errors. The only 
thing I thought to try was to add it to the exception list for the Network 
Inspection System. That didn't help. (FWIW, URL Filtering, HTTPS Inspection, 
Malware Inspection are all disabled.)

I have not tried putting the Firewall Client on his machine yet. It only just 
occurred to me that that might help.

Any thoughts about what might be going on or how to approach the problem?

Thanks,
Rob
