strange thing happend to me

["Sould3mon" <Sould3mon () killall net>]

i just restarted my system then a msg poped up
system shutdown in 50 sec (and counting downwards)
under it was showing  this pc is schuting down by
authority\system  with the adress c:\winnt\services.exe (donot remember the
correct line but it was the for remote terminal services  services.exe)

the sec strange thing
if i fire up power dvd and want to play a movie it say's
power dvd cannot run through terminal services
but if i click right mous button and then goto movie-file.mpg  (wich must be
added to the play list first otherwise this option is not available) then it
play's just fine

anyone that has any thought on this  how this happend ?

thanks
