Blank screen saver would look like that.  Thats the only thing I can think of that would be totally blank in a windows environment.  It may be that the computer isn't configured to come out of a scrensaver or password locked screensaver without a certain key sequence or won't respond to remote commands while in screensave mode.  You can configure those in power options, bios, display properties.  Might try ctrl-alt-del twice to see if a logon dialog comes up.  Otherwise,
I would scruitinize the vnc settings again.

Does someone else log on using fast user switching.  I noticed an issue with that and the screensaver also in some of the links above.

yes i think it is enabled

timothyfreyr
well when I connect there are 3 users to chose from when I select Admin which is the account I use to acces no problems before and put the password in I instantly get a black screen so I doubt its a screen saver because it comes on directly after I enter the password and press enter

as for fast user switching well... since there are 3 acc's on there then yes I think it has been enabled

by the way just to contribute from my experience into this

we had this same problem with another pc at another site and in that case the user enabled a firewall, I am not sure if it was the XP firewall or some personal firewall he downloaded and installed
