The server 2013 network is made up of three servers. SQL01, EXCH01 and TS01.
SQL01 is a DC
EXCH01 is also a DC running exchange 2013 network (Not recommended)
TS01 is a Terminal Server
After a period the users lose connection with EXCH01. We know this because it is manifested by Outlook 2013 getting unhappy that exchange has disappeared.
When this occurs and if users attempt to logon over this period they receive an error saying that the specified domain does not exist or could not be contacted. See notes attached.Naming-context-specified-for-thi.pdf
How is this fixed because when EXCH01 has this issue or is offline users receive this message that there is no Domain Controller available - What is SQL01 doing …. it will not authenticate users when EXCH01 is down?
The AD replication is broken but is it broken on SQL01 or EXCH01?
