CCA Connectivity Issue

[Dennis Xu]

After the move-in period, we had about 10 users randomly having 
connectivity issues to CAS. They can get IP from our Central DHCP 
server(CAS works as DHCP passthrough). But the dns lookup timed out. For 
the users having CCA Agent installed, the Agent did not pop up. It looks 
like the client cannot talk to CAS at all. Sometimes a 'repair'  could 
fix the issue. Anyone has seen the similar issue?

Thanks,
Dennis
