Dear Jack-Users, 
 
after some time I am back using JACK.
 
I am working with Win10, using JACK over network on two different machines. 
Last time I used it everythin worked fine. 
But now, on my master machine I get the following errors when starting JACK via qjackctl:

Drivers/internals found in : C:\Program Files\JACK2
jack_get_descriptor : dll jack_inprocess.dll is not a driver
jack_get_descriptor returns null for 'jack_inprocess.dll'
jack_get_descriptor : dll jack_internal_metro.dll is not a driver
jack_get_descriptor returns null for 'jack_internal_metro.dll'
jack_get_descriptor : dll jack_intime.dll is not a driver
jack_get_descriptor returns null for 'jack_intime.dll'
Drivers/internals found in : C:\Program Files\JACK2
JACK server starting in realtime mode with priority 10
self-connect-mode is "Don't restrict self connect requests"
Cannot connect to named pipe after wait = \\.\pipe\server_jack_default_0 err = 2
Cannot connect to server request channel
jack server is not running or cannot be started
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock
jack_deactivate called with a NULL client
jack_deactivate called with a NULL client
jack_client_close called with a NULL client

Apart from these errors JACK works and I can connect applications on this master machine.
 

But my slave does not connect. I followed this instruction to setup master and slave, but it doesn't work.
On both firewalls I setup rules with full access for jackd.exe for all ports and protocols.

As the same setup wworked some time ago, I am really stuck.

Has anyone an idea?

Thanks a lot for any help, all the best,

Christian
