Metadata error when running WCF service as particular user

I have deployed a WCF service that works great when the application pool runs as a particular domain user, but when I change the application pool to run as a different user, I get an XPATH error and my service doesn't even return metadata. I'm perplexed - my new user has permissions to all the service files (including config files), runs fine as an app pool identity, and database permissions don't matter because I can't even pull up a contract list.

Can anybody shed some light on this? I've attached the text of the error I get when I try to connect using the WCF Test Client. Changing the app pool to run as the first user and the test client pulls up a contract list, and I can call a method without any issues at all. Please save me!

Had a similar issue. I fixed it by granting the IIS_WPG group full access to the c:\windows\temp folder on the server.
