We had an issue with an IIS server, where the site would allocate
session ID cookies when you connected that would time out after far too
long.  Since we'd be connecting every 5 mins or more frequently for
checks, this resulted in session IDs being eaten and the server running
low on resources.

I agree this is a hosed server with a stupid configuration set up by
brain-dead people with no more knowledge than an MCSE, but sadly that's
what you get sometimes.

Management had two choices -
1) Fix the configuration of the IIS server
2) Stop monitoring it altogether

Which do you think they chose?  Sigh.
