I'm having a minor problem with WCS v.18.104.22.168. WCS is working correctly, but when I log off from the server, WCS stops.
WCS software is running as service and there is no other software running on the server. The system requirements and Windows updates are ok.
We experienced this exact same issue on a Windows 2003 Server. It is apparently a known issue with all advertised 5.2 releases. The Bug ID = CSCsx34113
We have found no workaround for it so have had to go back to 5.1 until Cisco release a fix.
Hope that helps.
