we experinced that after upgraded the Domain and Forest Level from 2003 to 2008R2, after a day, I cannot connect to my Hyper V Virtual machines with following error ” An Authentication Error Has Occurred. The Encryption Type Requested Is not supported by the KDC”. On the Exchange 2010 server, the transport server stopped and follow error message on application event log,
“ Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=xxxx). Topology discovery failed, error 0×80040952 (LDAP_LOCAL_ERROR (Client-side internal error or bad LDAP message))….”
“Process STORE.EXE (PID=xxxx). All Global Catalog Servers in forest DC=xxx,DC=xx,DC=xx are not responding.”
”Process STORE.EXE (PID=xxxx). All Domain Controller Servers in use are not responding”
A simple resolution to all this trouble is to restart the KERBEROS DISTRIBUTION KEY or KDC service on all Domain controllers. While simply restarting the Service will solve the problem, probably better off just doing a proper restart after upgrading your functional levels, only from 2003 to 2008 / 2008 R2.
