I doubt that too many other folks are having to deal with running PHP on the same machine as TeamSite, but if you are, here is something to keep in mind.
The PHP installation instructions suggest copying the required DLLs to C:\winnt\system32. Among these libraries is one called libeay32.dll. iwservletd is dependent on a library by the same name. Depending on what order it searches your library paths at startup, iwservletd may find the one in C:\winnt. If these happens, iwservletd will die the first time a user tries to authenticate.
This can be avoided by installing those libs not to C:\winnt, but to the same directory as the server api lib for PHP, php4isapi.dll in the sapi directory of the php installation directory by default.
