What does Cannot connect to server pipe mean? (err = 535)

[hockinsk]

I've got an ASIO client that appears to scan all available audio devices on the machine, but trips up with JACKsaying it can't connect to a server pipe. Is this a security issue I need to address? I'm pretty sure jackd.exe is in the firewall to let it do what it wants, but struggling to get this application to even see jack asio and connect.
