Just for a test case, write a 10-line ASP script that does something
similar, if much simpler, and pound on it on the same box with the
Padcom clients.
I'm betting you'll have the SAME ISSUE, and that the problem has
NOTHING to do with PHP whatsoever.
PHP works fine with IIS and Windows.
Or, rather, PHP doesn't make IIS and Windows any LESS stable than they
already were without PHP.

I'll say it again: There is *NOTHING* wrong with PHP and IIS.
IIS and Windows are badly-broken, all on their own, without PHP.

If you can prove it, showing the same problem in ASP, then what?
Are they going to let you move the application back to a real server?
In fact, you could probably get ahold of a Padcom and prove it to
yourself in a days' work, and then get them to agree that if it's not
PHP nor your script that's broken, but Windows+IIS, then maybe they
should just leave the WORKING stuff alone.
Probably won't work.
But that's how office politics work.
