What is open by default in windows server2008r2?

Question

System administration

There is windows server2008r2 with terminal server service probably hung up. There is no physical access to it. On the server, everything is configured by default from the moment of installation. How can you reboot it?
Tried winrs, connect through the computer management snap-in, PSExec. All this is disabled by default.

Answer 1

turn off the power in the area where the server is located.
get physical access - remote enikey, technical support for DC, etc.
