Hi everyone,
I have an issue, when trying to open my dsa.msc and "change domain controller" to a specific one, I always got "The following domain controller could not be joined: xxxxx The RPC server is unavailable".
I have this also with gpmc.msc
However this does apply to only one specific DC and for these consoles, all the others DCs are working fine and I can connect successfully to this DC with dnsmgmt.msc or the eventviewer.
I have a single forest/single domain configuration, all my DC run 2012 R2 OS and have 2012 R2 domain/forest functional level.
I also have to say that it used to work very well for quite a few months now. However, since friday, the network team put in place two Riverbed between the site where is located this DC and the site where I am (there is a MPLS link between the two Riverbed).
I clearly suspect this is the problem (the coincidence is very strong) but I have no way to justify it yet.
I've asked the network team to put the Riverbed in bypass mode, will see...
Firewalls have been checked and all AD ports are open (as it was the case before this network change) therefore I do not think it is FW related.
I did check replications and everything is fine on this point.
A dcdiag executed on this DC gives me "passed" test everywhere.
Any hint or advice would be very much appreciated...
Thanks a lot :)
