Issue/Introduction

In the Symantec Management Console under Settings>Notification Server>Site Server Settings, when selecting a site server and going to Install/remove services the check-boxes for Task Service and Network Boot Service are grayed-out.

If you look at the services pre-requisites, it shows "CEM mode disabled" as "No"

Cause

Task Service and Network Boot Service can only be added to Site Servers that meet certain criteria, one of which is that Cloud-enabled Management (CEM) cannot be enabled.  To verify this open the Symantec Management agent on the Site Server, open the Agent Settings tab, find the Network Status section, and check if CEM Mode shows either "Cloud-enabled Management mode is disabled" or "Cloud-enabled Management mode is enabled but inactive".

Resolution

To disable CEM:

1. Open the Symantec Management Console and go to Settings > All Settings > Notification Server > Cloud-enabled Management > Policy > Cloud-enabled Management Settings (by default this policy is disabled and should only be enabled in CEM environments). 
2. Find the "Applied to" section and select the target, then click the pencil (Edit) button to modify the target.
3. Click Add rule then specify a computer list or filter of the site server(s) that should not be CEM enabled.
4. Finally, click OK and save the policy.

The changes will take effect after a resource membership update runs and the site servers update configuration.

Note:
If you installed the Symantec Management Agent (SMA or Altiris Agent) on this server using a CEM package, you may need to uninstall/reinstall the Altiris Agent so the CEM policy is no longer present.

If CEM is not the issue then other criteria may not be met by the site server(s). To see these criteria hover over the Service that is grayed-out and it will list the requirements for that service, as seen below.
