- You publish a web server and authenticate all requests in a Microsoft Forefront Threat Management Gateway (TMG) 2010 environment.
- You set Authentication delegation to Kerberos constrained delegation (KCD).
- You experience a network issue such as a loss of network connectivity, or the domain controller is restarted.
In this scenario, the connection to the domain controller is closed, and TMG 2010 never tries to reestablish the connection.
If a network issue is experienced, such as a network connectivity issue, or the domain controller is restarted, the connection with the domain controller is disconnected. Additionally, TMG never tries to establish the connection again. This may cause TMG to leave the user name and domain name unformatted.
