Quoting Jim Moseby <JMoseby@nrbindustries.com>:

No. I wrote an ASP page that displays the same data with the same
refresh rate. When the PHP app fails, the ASP page is also
inaccessible. I thought this proved it wasn't a PHP problem, but
management was unconvinced that PHP didn't somehow taint IIS and cause
the problem.

> Can they PING the server?

Yes, which (in my mind) points to an IIS issue. I don't have the proper
knowledge of Windows or IIS to troubleshoot it, but one of my
co-workers has a theory about Windows and its dynamic routing tables.

I've discussed this with the network administator. That's going to be
one of our troubleshooting steps going forward.

Agreed.

My co-workers and I had a good laugh over this signature :-)

Thanks,
