Restoring communication to clients with a new Sylink.xml file
try re-installing the SEP and see if the client comes back.
This is a general error message indicating that communication with the server failed. Run the Symantec Endpoint Protection Support Tool to diagnose the problem.
I think the Wininet.dll file is missing on the C:\Windows\System32 folder.
If the file is missing restore it to system32 folder --> reboot
Do a repair installation of SEP then once again reboot the machine.
See if it helps!
Please replace the Sylink.xml
