Remote Procedure Control

[Dmitry Shevchuk]

I have an odd notice poping up suddenly quite soon after
booting:

The system is shutting down. The shutdown is initiatated
by NT AUTHORITY/SYSTEM.
Windows must now restart because the Remote Procedure
Call (RPC) serviceterminated unexpectedly.

And countdown starts from 60 sec.

It all began after some internet browsing.
Any ideas?
Thank you.
