Ok Thank's

I Try to Valid a ComputerName before used it in my { CreateObjectEx } because if the server is down it will take few minute before return the control to Fox.

Do you know if exist a API Function or something else that can do that king of Stuff ?

Ex:

IF ??? \\MyServer && need Fast Answer
x = CreateObjectEx("MyDcomServer.Main","\\MyServer")
ENDIF
