I have an internal web site set up on our sbs2008 server and it has been
working fine. Lately when users insert a new record they get the error 500 -
Internal server error.
There is a problem with the resource you are looking for, and it cannot be
displayed.

I have friendly http message disabled and I still get this error also so I
have no clue where to troublewshoot. I don't see anything on the event log of
my machine or the machine hosting the internal web site. Where do I start?
