I don't believe can stop services out right. It would have to be blocked or terminated.  Need to do it with GPO

You can block the wireless traffic, using this guide as a template

How to block all Wireless traffic when an Ethernet interface is active using Symantec Endpoint Protection

HI,

You can't Stop ICS services through SEPM adc policy.

You can do this for group policy

No no. Stopping the Windows Services using SEPM is not possible. But you can create a Firewall rule to Block the Wireless Traffic:

Block Wireless traffic using a Firewall rule

1. Select Clients> Policies in the Symantec Endpoint Protection Manager console.
2. Under "View Policies", select Firewall.
3. Double click the Firewall Policy for the "Ethernet" location.
4. Select Rules on the left
5. Click the "Add a new Blank Rule." button on the lower right side of the window.
6. Select the Blank Rule made in the previous step and move it to the top of the rule list.
7. Double click Action and select Block.
8. Double click Adapter and select Wireless.
9. Leave "Application", "Host", "Service" and "Time" as Any.
10. Click OK. The action is now completed.

Hi, 

Blocking the wifi adapter is not possible where all of our systems connect through wifi, few third party application software will modify the wifi adapter as wifi portable hotspot as access point where few users will connect it to using the sharing internet, I need to block only ICS services through SEPM application, ICS services will start manually when wifi hotspot software starts and stops when application stops.
