I have a user in Asia who can access *http://SERVER/sites/TopLevel* with no
issues, but when he tries to access *http://SERVER/sites/TopLevel/Subsite*,
he get prompted for a login. He enters his creds, but cannot access. I use
SharePoint-specific Active DIrectory groups, and his group is permissioned
on both sites.
Any idea why he would be getting this error?
