Trying to connect to VM through RWW, but receiving "the computer that you are trying to connect cannot be contacted. Verify that it is turned on, ...."

I'm trying to connect to one of my VM through RWW, but receiving next error: "the computer that you are trying to connect cannot be contacted. Verify that it is turned on, ...."

A weird thing is that through same RWW I can connect to other VM within same Hyper-V.

Problems started after W2008 ran updates.

Any suggestions?
