Can't log onto virtual server, very odd.

gregvyskocil · 2018-01-15T15:46:02.000Z

Have a hyper-v cluster of 3 servers. I have one virtual server I cannot access. I can do control+alt+del, enter the domain\username, then the password and hit enter. Nothing happens and I see the cursor is back to the end of the user name. I tried restarting the VM, I have shut it down and moved it to another server in the cluster with the same results. I rebooted the physical server it was on. Is the VM corrupted or something? Appreciate any advice.

Thanks

You don’t use control-alt-delete to log on to virtual machines with RDP connections, you use CTRL-ALT-END. Ctrl-alt-del will interact with your local computer.

RDP would not connect at all so was trying to connect in Hyper-v Manager.

This definitely sounds like something is wrong with the VM, not with the hosts. If other VMs on the same host(s) are okay, that suggests that as well. I think your assessment that the VM itself is corrupt or having a problem is, indeed, the issue. Maybe see if PowerShell remoting will gain you access - it’s possible that only the graphics subsystem is struggling and maybe from PS it can access it okay.

Sounds like an issue with the VM.

Try disconnecting the VM from the network and try again.

Try booting the VM in safe mode.

It is possible to shut down the VM, and then mount the VHDX directly as a disk or attach to another Windows VM. You can then attach the the event log files and see what if anything is getting recorded there.

I ended up reloading a backup .vhd and then got it working after fixing a few other glitches.
