There is a default system policy in Windows 7 that
prevents system services from sending Ctrl-Alt-Del (the Secure
Attention Sequence, "SAS"). Note that only the VNC Server in Service Mode may process this key sequence sent from a connected VNC Viewer.
There are two ways to solve this, either by setting the group policy to
allow services to simulate SAS, or by overriding the group policy in
place.
Either:
1.) Check that the "Disable or enable
software Secure Attention Sequence" policy is set to allow "Services" on
the VNC Server PC. (Please see related article)
Or:
2.) If you're unable to change this domain policy, you will need to
configure VNC Server with the SimulateSAS parameter. Setting SimulateSAS
to 2 in the Expert tab of the Options dialog will override the domain
policy for VNC Server. Since the server runs as a local system account
with administrator privileges, the server is able to momentarily change
the group policy to allow it to inject the SAS whenever it is sent from a
connected VNC Viewer.
