I am trying to create a NamedPipeServerStream as one user (non-admin, domain
account) from one C# console app and then connect to it via
NamedPipeClientStream as another user (non-admin, domain account) from
another C# app. I am getting an "Access to the path is denied" exception.
Both apps are running on the same computer (windows 7). I am running one
app via "Run as different user".

Both apps are running on the same computer (windows 7). I am running one
app via "Run as different user".
Both ends are being opened as PipeDirection.InOut
If I run both ends as the same user, all is ok.
Does anyone have any ideas?

Solution found. If I do this to create the pipe, it works.
PipeSecurity pipeSecurity = new PipeSecurity();
pipeSecurity.AddAccessRule(new PipeAccessRule("Everyone",
PipeAccessRights.ReadWrite,
system.Security.AccessControl.AccessControlType.Allow));
using (NamedPipeServerStream pipe = new
NamedPipeServerStream("pipetest", PipeDirection.InOut, 1,
PipeTransmissionMode.Message, PipeOptions.None, 512,
512, pipeSecurity, HandleInheritability.None))
The trick was setting up the security.
