Intermittent 802 Errors

[E.J. Sexton]

Okay, here's the deal:

My client is running a 2-machine deployment of FileMaker Server 9.3. Two weeks ago, their Domain Controller server died and needed to be replaced. We have a website set up using Custom Web Publishing.

Shortly after the DC was replaced, CWP stopped working intermittently for hours at a time. Everything else works fine--Users are still able to access the database using FileMaker Pro.

When CWP stops working, port 5003 stops accepting new connections on both the Worker and the Master machine. FileMaker reports this as an 802 "Unable to Open File" error.

Restarting IIS clears this problem up. Sometimes, this problem goes away on its own.

Recently, it seems like this problem will occur to some web users while other web users are able to use the website simultaneously without any problems, but we have not verified this.

I have tried restarting both machines as well as redeploying the CWP, but neither has helped.

Any thoughts or suggestions would be appreciated. Thank you for your time.
