Ok if that is the case, what is the registry key value that displays the port number that SEP client last communicated with SEPM console.
There are registry values, such as last SEPM communicated with, i.e.
HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC\SYLINK\SyLink
Registry Name: LastServerIP
Tell me the registry value of the port where client last communicated with SEPM on (at some point, Symantec recommended we configure settings such that client communicates on port 80) I can create a simple script and post it for Symantec community. :-)
Running Unmanaged Detector on SEP 11 is really user-unfriendly (you cannot copy and paste the results).
