I have a Dell Power Edge T620 Server, with Microsoft Server 2012 and Hyper-V server service installed. On my Hyper-V server I have a DC, Exchange server, File server, app server and 2 servers for a DNS service called Cisco Umbrella. Everything has been fine, but all of a sudden these servers are causing the Dell server to restart randomly.
I've logged into the Dell Server administrator and no errors, I've checked for errors in event viewer and nothing. I updated all drivers and firmware, I've made sure all window updates are done, but these servers still causing problems. This is the only error I receive right before the server restarts.
forwarder-va2' has encountered a fatal error. The guest operating system reported that it failed with the following error codes: ErrorCode0: 0xB76FD775, ErrorCode1: 0x40000000, ErrorCode2: 0xBF8D7408, ErrorCode3: 0xB774C000, ErrorCode4: 0xB774ED5C. If the problem persists, contact Product Support for the guest operating system. (Virtual machine ID 18468AB3-F650-4EF7-B33E-F00B85FA1748)
Any help would be greatly appreciated. Have a good day.
