You intend to install the Symantec Endpoint Protection Manager (SEPM) on Windows XP or Windows 7. Windows XP has a 10 concurrent connection limitation set by Microsoft. Windows 7 has a limit of 20. This guide contains the configuration changes that are necessary to work around this limitation. This is supported for up to 100 clients managed from a single Windows XP-based Symantec Endpoint Protection Manager.
Follow these steps before you install a client through the management console:
Log in to Symantec Endpoint Protection Manager.
Select the Group to configure and turn off Policy Inheritance (if at a level other than My Company).
Under the Policies tab, click the Communication Settings link under Location Independent Settings.
Set the Download radio button to Pull Mode.
Set the Heartbeat Interval to at least 30 minutes (60 minutes recommended).
If the Windows Firewall is kept active, you will need to create an exception for the Symantec Endpoint Protection Manager communication port.
Open Control Panel
Open Windows Firewall
Click on the Exceptions tab
Choose Add Port
Name it something meaningful, like "SEPM communication port" (or something similar).
Port number will be the one you chose during installation. The default is 8014.
Click OK, and then OK again
Note: This change only needs to be made on the manager, not the clients.
Now the clients can be deployed and communicate successfully with Symantec Endpoint Protection Manager.
