Unable to establish connection with session error 10030
We have been using Ghost 11.5.1 for the last 12 weeks and all has been going well.
Suddenly this week I cannot connect to any session, it times out with an "Unable to establish connection with session error 10030" message.
This is the same if I PXE boot from the ghost server or boot from USB.
BUT if I enter the server address under "Discovery Methord" when specifying the session number it connects straight away.
Any ideas what might have changed or how I can fix this?
Thanks in advance.
