Looks like a recent patch from Microsoft has caused some view clients to stop connecting. VMware is aware of the newly discovered issue and is advising customers to not install the MS Security Patch. If the patch was installed already, the work around is to uninstall. More information can be found on VMware’s Support pages.
“As part of our commitment to letting you know about emerging issues, we want to mention an issue a few VMware View users are running into after applying a Microsoft patch.
