Problem with Named Pipes between Win7 and XP Pro

Hello,

I am trying to solve a named pipes problem. I have a small wireless LAN (westell router is gateway). I have written a small client/server app in C. When the server is on a Win7 machine and the client is a Win XP (Pro, SP3), the app runs fine. The named pipe works as expected.

However, when I reverse the roles of the two machines the pipe fails. When the server is the XP machine and the client is the Win7 machine, the pipe fails. The code running on both machines is exactly the same and is invoked the same way by CMD.exe.

I have turned off the firewall on the XP machine.

I should also mention that the two machines can share files and printers without a problem.

I'm baffled.

Thanks for any suggestions you might have. I have googled until my fingers are sore.... perhaps an exaggeration.

Regards,
Mark Allyn

Does it fail with an error message, throw an exception or just silently.
