I have a domain with a few subdomains.
I have 1 Exchange server, they all get email from one server.
At 1 site I can't get email. It won't authenticate a user. nslookup works, ping works, tracert works. I can ping servers to and from this site...
I'm also having problems with AD replication...I'm getting replication errors from replmon also....
DNS appears to work....i can ping by ip, netbios name and fully qualified name....
The site has it's own domain controller, but if I login a user from another domain, it logs them in across the WAN...If I login a user from the domain where this site is located, It authenticates with the local DC

Replication Failure: Changes have not been successfully replicated from ServerXXX for 365 attempts
Replication Failure: The reason is: The remote procedure call failed.

The problem was actually a router issue...the replication errors and Outlook access was resolved by the company that manages my new MPLS.

Thanks for the suggestions

I am glad to hear it worked out.   Thanks Bernardb.  

I am curious to what changes did they have to make on the router?  Change an IP route?  Tx.
