Thanks for the links. I've read most of them.

I'm not sure what alternate forms of SetProperty means. There is a form that takes @ARGS as a parameter before the value you want to set, but I have no idea what that is for.

I have tried setting different values:

SetProperty("msTSConnectClientDrives", 0);
SetProperty("msTSConnectClientDrives", 'No');
SetProperty("msTSConnectClientDrives", 'False');
SetProperty("msTSConnectClientDrives", Variant(VT_BOOL,0));

Only the last one does not give an error, but it also doesn't change the check box.

I have been able to set other TS properties. For example, TerminalServicesHomeDirectory. None of the ones that start with msTS* work though. Maybe there is a different name I should be using?
