Dears,
I have the following problem,I hope someone would be able to help me here.
I have a forest of one parent domain (ZMC) which has two domain controllers (ZMCDC01,ZMCDC02), and a child domain (ZMCUCC) which has one DC (ZMCUCC01), my problem started with not being able to setup the e-mail of the child domain users on outlook nor accessing the Outlook web access page on the exchange server.
Later on i ended up with running dcdiag tool /test:replications to get the following results:
Domain Controller Diagnosis
Performing initial setup:
Done gathering initial info.
Doing initial required tests
Testing server: SMSSite\ZMCDC01
Starting test: Connectivity
......................... ZMCDC01 passed test Connectivity
