I'm trying to deploy a Zen 10 agent to a Vista machine. I've got the Windows firewall turned off, remote registry turned on, file sharing turned on and the registry hack mentioned in the documentation. When I try to deploy the agent I get the error Cannot connect to machine. I also have a proxy server configured. I don't believe I have SP1 installed on the Vista machine. I've looked at the patch list and didn't see SP1 listed there. Any ideas on what's wrong?
