401.1 - Integrated security issue on local machine only

I recently upgraded our development application server with SP1 for
Windows Server 2003 and the Web Services Enhancements 2.0 SP3. Now our
developers receive "HTTP Error 401.1 - Unauthorized: Access is denied due to
invalid credentials" when they attempt to work on their VS.Net 2003 web
projects via Remote Desktop. In fact, any attempt to access the virtual web
while logged into the local machine causes IE to prompt for credentials and
ultimately return 401.1. Remote clients can still access the applications
through IE. It is possible to bring up the virtual web on the local machine
using its IP address instead of the DNS host name.

Thanks for your consideration,

Chris

Chris,

I had exactly the same problem and solved it by disabling the loopback check
as described in Q896861.
