When you try to open a console window to a VM from a VMware vSphere Client running on Windows 8, you may find that you just get a black / blank screen with the following error:
The VMRC console has disconnected… attempting to reconnect.
There is hearsay on the internet that the open console aspect of the vSphere client relies on APIs in Internet Explorer that are no longer available in IE 10 (which ships with Windows 8). Unfortunately, at this point in time there is no fix for this issue. The VMware vSphere Client is just not compatible with Windows 8 at this time. A workaround is to install a Hyper V VM running a previous operating system, such as Windows 7 and run the vSphere Client on that VM instead.
Adendum: The VMRC Console Has Disconnected issue has now been fixed with the latest version of the vSphere client (free download from VMware) 🙂
Thanks to a comment from sticks221, who highlights that the VMRC console has disconnected error can be fixed by uninstalling Internet Explorer 10, if you are using a version of windows prior to Windows 8 😉
Thanks also to Tsumu, who pointed out that the VMRC console disconnected issue can also be caused by your anti-virus blocking the IE plugin 😮
