What is causing Sonicwall TZ-170 to intermittently drop HTTP and HTTPS connections to OWA and Remote Access?  It was working fine for months, then 6 days ago it started to drop any remote web access.  The problem is intermittent.  Things will work fine for 10 or 20 minutes, then drop again and stay down for over an hour at at times.  Access to OWA and Remote Web Workplace work fine if we access from internally, by using the servername/exchange or servername/remote.  My boss thinks it's our Sonicwall hardware just starting to flake out.  Could any of the settings be causing such intermittent issues?

Our system:  SBS 2003 running Exchange 2003 and IIS6 behind a Sonicwall TZ-170

First question is (as usual): did you change anything on the TZ? E.g. does it run security services.....
How old is it (just had once a PRO1260 failed)
If no, chance for HW failure
If yes, turn off services, check

Turned out to be the second Network connection on the DC.  I noticed it was running much more slowly than the primary, so I unplugged it.  Everything started to work, OWA, RWW, even our internet access speeds improved.  Still don't know why this suddenly became an issue, because it was setup like this with 2 NICs on the DC for over a year, but disconnecting the secondary NIC has resolved all of the issues.

what was the servers 2NIC configured to? Teaming? What about the switch the NIC (and probably the FW) are connected to? It difficult to analyze with no information about the topology and configuration.
