Remote Exec -> RPC Problems

[stony007]

Hey..


i have to write a app, witch can call a process on a remote computer!
after some google time i only found the following article:

http://www.thescripts.com/forum/thread387736.html

so i create a RemoteExecute.dll with th dll code and a Remote_Form1 with the example code.

if i fill the "remoteSrv" string with my local machinename, it works fine and the notepad start.
But if i set the sting to an remote system (WinXP) without any firewall, i get a RPC Error in the line "watcher.Start()"


The RPC-Server is not reachable HRESULT: 0x800706BA


the remote server is online and fully reachable!

where is my problem?
dose anyone used this code successful?
has anybody another methode?
