Several VMware users reported yesterday that Microsoft’s latest .NET patch was locking them out of the vSphere Client.
Users on the VMware Communities forum and other message boards said the patch prevented them from logging into the vSphere Client — both on Windows 7 and XP. (The patch addresses a vulnerability that leaves signed XML data open to tampering.)
Some users overcame this problem by uninstalling the patch (identified as KB980773, part of update KB982168), which obviously isn’t ideal. But the better solution is to install the latest version of vSphere Client 4.0 Update 1.
Did you run into this problem yesterday? Did that solution work for you? Let us know in the comments below.
