SYMPTOMS
Clients cannot log on to the domain if the clients use Kerberos over Transport Control Protocol (TCP). Clients that use Kerberos over User Datagram Protocol (UDP) can log on correctly.



CAUSE
Kerberos may stop accepting connections over TCP. This condition is temporary; Kerberos recovers and begins accepting connections again after approximately two minutes.
