I am running HP JetAdmin versjon 10.4.99821 (10.4 SR1).
We have the same setup for two different computers, one running W2008R2 and the other W2012R2. The latter was set up using a backup from the first, so they should be identical.
Both servers are on the same subnet and both have the local firewall set off.
What I want to do is to open the application from another server, by accessing the following link: http://<servername>:8000/wja/wja.application.
My new server are able to reach the old server that is running W2008R2, but when I try the same fron my the old against the new W2012R2 server, it freezes at "Setting up remote channel", until it errors out at "the service could not be contacted, make sure the service is started before running the client".
If I run the same link locally on the server where WJA is installed, it works without any issues.
Port 8000, 4088 and 4089 are all open. There are no firewalls between these two machines either.
I have also checked the http://<servername>:8000/diagnostics. The new and old server both reports all the same services up and running.
The first remote try after restarting the HPWJA service on my 2012R2 server it gets past the "Setting up remote channel", but it stays on "waiting for service to start" for several minutes. It then passes over to "Establishing secure channel" for 10sec untill it resolves with the same error message as before. And yes, this only happens on the first try after a service restart.
