Hey Marcia,

It might be a permissions issue or a framework version conflict. Go into IIS and see if the page is logged OK and then check the .Net tab in properties in IIS to see if the right version of the .Net framework is being used for that page.

Also, try subsituting the loopback IP 1.0.0.127 in place of localhost. I dunno why (no one ever mistook me for a Windows engineer) but sometimes that overcomes some permissions issues in some versions of W2K3 or W2K Server.

I have spent days chasing garbage like this around.
