I have 3 Servers all running Windows Server 2019 Standard, Domain server, Web Server and a Data Storage server.
Whilst copying data from a shared folder on Data server to a shared folder on Web Server - both servers froze during the process and had to be rebooted. After this, I get periodic issues with one of the servers not connecting to the Domain/Network. When I use Domain server to look at other servers I get the error - "Kerberos Authentication error" and I can't login remotely (which I often do).
The only way I have managed to fix the issue (temporarily I expect) is to disable the NIC and enable the other NIC, rebooot, the re-enable the original NIC. All 3 Servers have 2 NICs.
Any guidence appreciated.
