We have several Windows Server 2008 R2 servers across different companies we provide remote support for. Each server is installed with LogMeIn Central.
When we try to login remotely (LogMeIn) to any of these servers we get stuck on "Verify Identity" step and then it disconnects our session. We tried Remote Desktop connection and we connect but we can only see a black screen and nothing else! Can't ALT+CTRL+DEL or so...
I've had a technician on site and he physically connected a monitor/keyboard to server and there was no output on the screen! Additionally the keyboard was not responding!
Server roles (DHCP, SQL, AD, etc) appear to be working normally.. we just cannot login!
Anybody out there experience the same thing. All servers are on different locations so it's unlikely that it is a virus. The only thing these servers are sharing is the choice of antivirus software: AVG Business Edition (2012, 2013, 2015, etc...) and remote management (LogMeIn Central).
When we power cycle the server it works fine for a while and then the same issue re-appears. Event Log doesn't seem to point to anything obvious.
I suspect AVG Business Edtiion software to be responsible but it's more of a gut feeling rather than decision based on facts.
Anyone come across this before? Any hints? Thanks,
