Hi.
I have an authentication problem with my Windows XP clients. My server is Windows Server 2008R2 with NPS installed and configured for Wired 802.1x. The setup should be fine as my Windows 7 machines can authenticate correctly if they have a certain computer certificate.
The error code in the log is 07 - No Such Domain
When I look at the log more closely I can see that somehow the authentication request shortens the computer name of my Windows XP machine, and thats why it cannot recognize the domain name. No matter which computer name I choose for my machine it always shortens the name to 11 characters. An example:
Working Windows 7 authentication log:
User Name: host/computer7.domain.localConnect Request IAS_SUCCESS
Windows XP authentication log for two different computer names (xp.domain.local and winxp.domain.local):
User Name: host/xp.domain.lConnect Request IAS_NO_SUCH_DOMAIN
User Name: host/winxp.domaiConnect Request IAS_NO_SUCH_DOMAIN
Any suggestions on why the computer name is cut off? Thanks.
