I had to send a laptop to be repaired & they replaced the mainboard. When I got it back I thought I'd installed Windows updates before re-connecting it to the domain, because there's a Features Update available that won't install while its on the network. So I ran the update & now the laptop can't reconnect to the domain, I'm getting the error "The Active Directory DOmain Controller (AD DC) for the domain "xxxxx.local" could not be contacted".
I found the thread https://www.experts-exchange.com/questions/28996502/THe-Active-Directory-DOmain-Controller-AD-DC-for-the-domain-che-local-could-not-be-contacted.html
, which exactly describes my problem, unfortunately it ends with the laptop being replaced. I've tried editing the "host" file, I've tried all the ipconfig commands, I've installed an update to the 1803 Feature update, I've hardcoded the DNS server addresses into the network settings, but still I get the error. Frustratingly I can see the server in the network, I can even connect to it if I put in the admin login & password, I can ping it, I can ping the router, I just can't join the domain.
When I restart the laptop, I always get this same set of Event Log errors from DistributedCOM, event ID 10016, is this possibly connected to the connection issues?
"The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool."
I have no idea if the problem is related to the mainboard being replaced, or the 1803 update. Any ideas?
