We have had to remove a corrupted group policy and create a new one.
A bizarre turn of events following this change which seems too much of a co-incidence..
2 of my main VM host servers have now been locked down and I cant access them remotely or even directly plugging a monitor and usb keyboard.
I cant rdp to either the host or the guest vm's, or connect a session through ILO on the host, even connecting up USB or VGA directly to the servers - I get no vga signal and no power to the usb.
I cant understand how even the hardware connections have been locked down !
These two servers are Proliant DL380 running server 2012.
Other servers on the network seem unaffected, these are running 2003/2008 server.
Any thoughts on why these two identical 2012 servers have been affected this way. I cant believe its a hardware fault on both servers at the same time..
