When connection is not established, OfficeScan immediately treats the computer as 
unreachable. The default port number is 135.

a computer cannot be established, the OfficeScan server no longer needs to 
perform all the other connection verification tasks before treating a computer as 
unreachable.

displays the result. Otherwise, the current query session terminates and the query 
process restarts.
