Sysvol Replication not working to 1 DC out of 3
Have googled around but couldnt find anything to fix our issue.
Have 3 DCs all running Windows 2008 R2 Server, 2 of the DCs including the Master are working fine but number 3 being our exchange server is failing. Any chances to the Sysvol folders on the 2 working DCs are not replicating over. This issue DC has got exchange 2010 (been installed for a year now) issues must of occurred in the last 6 months which must have something do to with our server upgrades?
Have tried the following:
Folder Permissions all match
Servers can access each other name/ip no problem
DCDiag looks fine minus an alert 20 (event log is Schannel alert 20 and 10 - quite a few of them).
IP Config /all looks all right
Repl all looks as well - all succeeded
I have manually gone in and change the GPO settings on this DC temporarily which has resolved our basic issues.
Looking at DNS I can't see no obvious issues, I have noticed that email is appearing in OurDomain-DomainDNSZones/TCP (and Sites TCP) and ForestDNSZOnes TCP (and Sites TCP) even though its not a DNS?
Also: An old server which was demoted and now only a member server (till we can transfer the public drive data then its out) is appearing in the msdcs.OurDomain - Domains/TCP and DC/TCP folders. Even though its not a DC just a member server (this is windows 2003 server box which will be scrapped).
Not sure what else to add but as you can guess I have tried a few bits and bobs. Any help will be great thank you.
