RPC Server not available on a Server + AD replication

Hello Experts

I have a Curious Issue I am tryning to migrate AD from win 2008 to Win 2016
I had one DC that was in shortage of space in the C drive

A guy Lucnh an operation to virtualize the server and i think the Operation did not go well but now when i type repadmin /replsummary

I have errors of RPC server not available on this DC that was restarted and now replication reporting errors

Nothing change in the configuration Except the DC hang and was restarted

And something else during the nigth the command reported the DSA Source and DSA Destination

Now it is reporting only DSA Source

Alex

ok,

How many DC's are in your estate, why didn't you just build a new 2016 box and then migrate the FSMO roles to that?

Do you have a working AD at the moment or not?

Thanks
Alex

Yes i have a working AD now

I have 5 DC ( 3 in the Faulty Site and 2 in another Site)

but i wanted to update the Schemas but the problem is My Replication is not clean on that Server

So i can not proceed to add Win 2016 boxes

Also i have Multiple errors 7055 on my DNS Server of the problematic DC

the accept function of the Server....

Decomission that box out of your environment, if it's currently Unstable and you're planning on upgrading, remove it completely.

Then migrate to 2016 and update your functional levels.

Hello It is not that Easy the box is holding DHCP and CA roles

But i definetly have a DNS problem

This is what i have when running the Dcdiag /test: DNS

I don't speak french, can you copy and paste it into google translate for me?

And if it were me, I'd migrate those off and then DCpromo it out of the domain.

Can you run dcdiag /v from elevated cmd on PDC master (language should be English) and post back here?

This question needs an answer!
