Runing an IIS server, it seams like the php4isapi.dll module interfears with the Exchange server on the same machine. PHP also seams to encounter several acces-violations randomly during runtime.

The errorlogg on the machine shows (from startup): 
"A fatal error occurred while creating an SSL server credential"
The errorlogg on the machine shows (during IIS failiure):
"The HTTP server encountered an unhandled exception while processing the ISAPI Application '
php4ts!hashpjw + 0x13
 + 0xA05E5983

We are possitive that it's the module causing the problem since when the IIS runs the CGI version everything works perfectly (except from the "header" function, wich we require). 

The module is not installed as a filter, only as an ISAPI application. 

would be thankfull for anny help!

rock solid, though with a slight performance penalty, or 
if you can, switch from IIS to Apache and run the Apache

Thank you for taking the time to report a problem with PHP.
Unfortunately your version of PHP is too old -- the problem
might already be fixed. Please download a new PHP
version from

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
