Logging into Vista Workstation results in error:
"Can not connect to TAC Vista Server, No such interface supported"
Some connection between the Vista Server and the LNS Server has been broken. This is because of some change to the PC configuration: virus scan, Windows updates.
You have installed a component of a different version.
- Uninstall TAC Vista, system plug-in etc.
- Delete any TAC Shared folder in the \\Program Files\Common Files catalog
- Reinstall Vista
