We have six Digi hardware devices in the field. Don't know their models - that is another group. I handle the software side. This weekend, 5 of the 6 Digi ports stopped communicating with the hardware. We use Vanguard to control our signs. I've stopped and started the Digi service on our Vanguard servers. Also rebooted our test Vanguard server. Anything else I should try or look for?
Remote hardware are Digi Transport WR44 R and Digi One SPs.
Server OS are Windows 2008 R2 SP1 64-bit OS.
I’m seeing this error on the test server:
System.Exception: A connection could not be established to display XXXXXXX). ---> System.UnauthorizedAccessException: Access to the port 'COM15' is denied.
On the Prod server the error is:
System.Exception: A connection could not be established to display XXXXXXXX). ---> System.IO.IOException: A device attached to the system is not functioning.
