Windows – Explorer.exe stops working in Windows Server 2008

I'd need to know what virtualisation platform you're using in order to tell you if you were able to tell from outside of the machine, but if you're logged on to one of the VM's you can find out in Task Manager.

Right click the taskbar, select 'Task Manager' from the pop up menu and then navigate to the 'Users' tab on the dialogue box that appears.

It should tell you the username, which physical machine they're running the session on, the status and the session ID.

You will need console access (i.e. be ON the physical server) to reset the password, if you don't have any other passwords available. Is this server connected to an AD server? If so reset the password on the domain controller. If it is only using local usernames and passwords, try something such as the UBCD4Win CD to reset the password.

The way that passwords are stored for users of a Windows system, you can not "recover" or "view" the password in clear text, only hashed form. Because of the vast possibilities that could create that password, you're better off clearing the password, and setting a new one
