I have created 2 x DCs in Hyper-V and in DC1 (FSMO, GC, DHCP, DNS) produces the following logs in event viewer:

Code:
The winlogon notification subscriber <gpclient> is taking long time to handle the notification event (CreateSession). Event Id 6005
 
The winlogon notification subscriber <gpclient> took 92 second(s) to handle the notification event (CreateSession). Event ID 6006
DC2 is absolutely fine. Any one have any ideas about this?

I have searched high and low but to no avail.
