You cant run "windows" applications on a remote server using WMI.

Sorry, I wasn't being clear enough. The problem isn't with the
'calc.exe', that opens fine on locally, was just used to illustrate the
similarity in the procedure. The point is that the
processClass.InvokeMethod("SetAllowTSConnections", methodArgs); gives
me an exception, which it shouldn't.

"You cant run "windows" applications on a remote server using WMI. "
<--
that is not true though, if you specify admin username/pass for the
remote machine you can run applications using WMI.

"Windows" applications, these are applications that have a UI canot be
started on a remote server.

It was written on the top of the first post, but here it is:

Try with boolean status instead of an int.

No luck :(

Im beginning to think that I have to somehow call the method on an
instance of the Win32_TerminalServiceSetting and not on the class
directly, but I have no idea on how to accomplish it, any ideas?

I've reported this as a bug on msdn.

Thanks for helping, I really appreciate it.

Yes, you need an instance, this should work...

SelectQuery q= new SelectQuery("select * from
Win32_TerminalServiceSetting");
using(ManagementObjectSearcher searcher = new ManagementObjectSearcher(q))
{
ManagementObjectCollection TS = searcher.Get();
foreach(ManagementObject o in TS)
{
ManagementBaseObject inputArgs =
o.GetMethodParameters("SetAllowTSConnections");
inputArgs["AllowTSConnections"] = 0;
ManagementBaseObject outParams =
o.InvokeMethod("SetAllowTSConnections", inputArgs, null);
uint ret = (uint)(outParams.Properties["ReturnValue"].Value);
if(ret != 0)
Console.WriteLine("Failed {0}", ret);
}
