Hello Everyone,
I am having an issue with my primary domain controller. The issue i am having is that the secondary domain controller is not replicating to the primary domain controller. There is an error when forcing replication that the server displays stating that there are no more endpoints available from the endpoint mapper. My primary domain controller is also my federation server that syncs with Azure for directory sync with office 365. I have run through all troubleshooting steps listed on every site i can find with RPC 1753 errors. And all i can find is a way to verify that i am having the error which i am most certainly having. But nowhere has an answer as to how to fix the issue with the endpoint mapper. I cant seem to find a solution as to how to fix the RPC error. I have verified that the RPC service is running and set to automatic and the the endpoint mapper is also working correctly running and automatic. All the changes have been made to the secondary server and are not appearing on the primary server. Both of them are GC's so I am not having any issue with logging in or connecting to the servers. But any time a change is made to an account or computer is added to the domain. It only shows up on the secondary domain controller. DNS is working correctly and the port 135 is listening on the problem server so it does not appear to be a firewall issue as the firewalls are turned of on the servers while i am troubleshooting this. So it is not a firewall error or port error. Both services are running so it is not a stopped service. I can not change any of the options for the rpc services though which i don't know if that is correct or not. I am really looking for a solution and not another way to figure out if i am having the problem because as you can see I am having the problem but have no solution. Please let me know what logs i can send or info i can supply to help resolve this issue. I could of course erase everything and start over from scratch but i really really don't want to do that because of all the specific installations and files i have on the server along with accounts and password of my company. If that is the only solution then so be it but i want to try everything possible before reimaging. Please let me know what further information you may need or anything i can try to correct this error. Thank you very much in advanced for all your help!
