named pipe issues

I am rather new to pipes, but I have two c# programs that are communicating via a named pipe. This is working fine on two of my XP Pro SP2 machines. However, when I port to a third machine (also XP Pro SP2), I cannot connect to my named pipe. Are there any simple permission/access issues that need to be considered with named pipes? The pipe is being accessed locally, so I don't need to access it accross a network.

The code for creating my named pipe is;

SafeFileHandle clientHandle =
CreateNamedPipe(
this.pipeName,
DUPLEX | FILE_FLAG_OVERLAPPED,
PIPE_TYPE_MESSAGE | PIPE_READMODE_MESSAGE,
255,
BUFFER_SIZE,
BUFFER_SIZE,
0,
IntPtr.Zero);


Many thanks,

Jeb
