Cannot open named pipe through NAV 2013 Service Tier

I have a .net dll that opens a named pipe to start listen. It work fine from a .net Windows form application, but when calling it from NAV 2013 Service Tier I get an System.IO.IOException with HResult: -2147024665, "all pipe instances are busy". Same behaviour on several computers, so it seem to depend on the Service Tier since Windows form application can run it. The NAV server is running with the same account as the execution of the Windows form application.

How can I make it work from NAV 2013 Service Tier?

(For your information, same behaviour when dotnet variable is set as RunOnClient)
