We have an ASP site that runs in IIS 6.0 under Windows 2003 (uses SQLServer
as well). The main users of the site run IE on 4 computers behind a router
which acts as a firewall. The site is very simple on uses only old ASP style
code (i.e. no .net).

The site runs fine for few days then suddenly they get this error (see
subject line). We've tried serveral solutions to get people working again
(re-boot computers, re-start web site, re-start web site service on windows
2003) but the only thing that seems to get the train back on the rails is
re-booting the modem which connects the remote office to the Internet and
waiting about 15-20 minutes.

This is not a dns or internet connection issue. The site still works at
other locations (around the world). The users can still get at other sites on
the web while our site appears dead. The users can also use ping and tracert
to find our server.

I have not found out what the telco is doing when the modem is re-set but I
think things will point back to IIS 6.0 not liking 4 sessions pounding away
at it through a firewall. We seem to be hitting some kind of threshold in IIS
6.0

Does anyone have any ideas why this might be happening? Thanks
