Hi rsellers
That, unfortunately is down to the remote PC I think - I find nearly every time that Remote registry is disabled on the PC. This stops access to things like the Device manager
You could run these each time you need to connect remotely:-
sc \\<pcname> start "RemoteRegistry"
sc \\<pcname> start "PlugPlay"
You could possibly do something with AutoIT to create a script that starts the Remote Registry service, then tries to run the Device Manager? Something similar was done with connecting to the registry of a remote PC:- http://www.lansweeper.com/Forum/yaf_postst1395_Connect-to-remote-registry-tool.aspx#post6491
Hope all that helps
