If I visit the address:
http://localhost:8260 I can browse my site without any problems.
If I try http://machineName:8260 I get prompted to login, and my credentials don't work.
Any ideas on how to fix this?
I manually edited the host in IIS to include the fully qualified name of the machine, then restarted IIS, and now can access the site using machineName.domain:port.
