RPC server is unavailable

After latest update in Monday (11.1.2022),
our Windows server 2019 domain controller was crashing every 4 minutes or so 
After trying to log in via RD or Hyper-V, server replied "RPC server is unavailable" and crashed.

I fixed the issue with removing virtual network switch for DC (I guess removing network cable will work similarly), logging in and uninstalling update KB5009557. 

 

Hope this helps somebody.

    Seems to be a known issue. Anyone can call Microsoft support…  whether they have a pre-paid support contract or not.   And all cases closed as bugs are refunded.

      I mean, yeah if you sepcifically search for that specific update, you find it as well-known bug. I made this thread for people who use google first because googling RPC server is unavailable finds you nothing usefull for this case. Really didn't think about another broken update in the first place.
