[PHP-WIN] strange problem configuring two sites in IIS

[Carlos Andre Marques Moreira]

Hi,
I've been runing php3.0.15 + w2k +iis 5.0 + mssql 7.0 for some time without
problem.
Today i tried to setup a second site on IIS, and now i'm having some
problems running php files. When i access the site it executes the php file,
but if i try to access it again i receive a error (http 500)
Previously, i was running this new site as a directory of my older site, but
as this is a new project a decided to make a new site on IIS e let them
separate. when i was running it as a directory the scripts were running with
no problem.

Some idea?
