Windows Server 2008 Core - change screen resolution
One really annoying thing about the VMware Tools installation is that it reverts the video mode back to 640×480 for Windows Server Core installations; barely enough space for the command prompt. This can be fixed very quickly. Run regedit (one of the few GUI tools in Server Core) and find the keys DefaultSettings.XResolution and DefaultSettings.YResolution. Hint: they’ll be in a subkey of HKLM\System\CurrentControlSet\Control\Video\. Change these values from 640 and 480 respectively (another hint: change the value from hex to decimal!), reboot and you’re good to go.
