Endpoint Protection

I use Win 10 Pro and Symantec Endpoint Protection which is supplied by university. I upgraded from 12.1.6 to 12.1.6 (12.1 RU6 MP3) and now my homegroup network doesn't work unless I disable the Network Protection Threat. How do I get around this problem?

Check the Traffic log on your client and see what is being blocked. This log should all traffic that is blocked. You may need to add a rule to allow it. Post the log here for review if you need help deciphering it.

log attached. If needed how do I set up the rule?

Microsoft has a list of ports that should be opened for homegroup to work correctly here:

Adding a firewall rule on an unmanaged client is here:

Firewall policies on unmanaged Endpoint Protection clients

Open your SEP interface and select Options next to Network Threat Protection. The select Configure Firewall Rules.

I "allowed" UDP 3702 and 5355 and TCP 5357 and 5358  which were the only "rules" I could see but the blockage is still there.

Did you place that rule at the top?

my rules look like (See attachment)

You may want to look at the troubleshooting guide to see if some traffic is not being logged accordingly:

Troubleshoot blocked network traffic due to the Endpoint Protection firewall

I gone thorugh the rules & it looks all the way customized as per the business requirements. Best bet could be roll back SEP client to the previous version. Is it possible?

That is a good idea. My it department are on holidays till next week. I will ask them then.

Thanks

Is there any update?

OR

If issue has been resolved mark this thread as a solved with the best answer that helps you.

I couldn't get a previous copy of the program so I have had to disable the Symantec firewall and network intrusion protection. My network now works perfectly.
