PHP4 & ISS Problem

I have an NT4 IIS4 server. IIS runs fine until I try to run a PHP script. The script will run (it contains 'phpinfo()' only) and I get what I expect, but if close the browser then try to reopen the same script it doesn't work and IIS has shut down. The event viewer doesn't report any errors, but the page displays HTTP 500 - Internal server error Internet Explorer and after that either the whole IIS server shuts down or any php page will get the same result, until I reboot the NT server. ---------------------------------------------------------------------------- ---------------------------- Intaxication: Euphoria at getting a tax refund, which lasts until you realize it was your money to start with. dmalcolm@hiwaay.net
