I was away on vacation, and a dev box ran out of space. Once I got back, I cleaned it up, rebooted and still could not connect to it. @xrobx99 noticed an IPSec message in the event logs:
The IPSec driver has entered Block mode. IPSec will discard all inbound and outbound TCP/IP network traffic that is not permitted by boot-time IPSec Policy exemptions.
We thought that was suspect as we weren’t using IPSec policies. It seems that our server ran out of space and the IPSec policy became corrupted.
I ran the command :
This command rebuilds the local policy store. I rebooted and all was fine.
Hope that helps someone.
