SYMPTOMS
Users cannot connect to a Windows Server 2003 domain by using a virtual private networking (VPN) connection. This problem occurs if the following conditions are true:
 * The users try to connect to the domain through a Cisco router.
 * The Cisco router uses Kerberos authentication to authenticate the users against a Windows Server 2003-based domain controller.



CAUSE
This problem occurs because the Key Distribution Center Service returns the wrong user name format to the router.
