Currently when users access any of our windows 2003 citrix servers via the web interface, locked sessions default to "<ServerName> (this computer)" instead of the domain that they are logged in with. I have checked the DEFAULTDOMAIN and ALTDEFAULTDOMAIN reg keys and they are set to the proper domain. When logging into these same servers via Program neighborhood or through remote desktop, the problem goes away, so I know it is an issue with the web interface.
Any help would be appreciated. Our clients are rather annoyed that they have to hit the drop down box when unlocking their sessions.
