are you using Windows Admin user account?
Yes, of course.
Yeah, just confirmed to access Norton 360 ā Settings from Standard user account. Ya need to Sign In as Admin.
So, ignore my question = are you using Windows Admin user account?
I donāt know what youāre trying to say. I am logged into Windows using an Admin account, yes. What else?
I canāt even change this setting from Smart Mode to Ask, for example:
Iām trying to sayā¦ignore my comment re Admin user account. Norton 360 v22 ā changes to Settings was limited to Admin user account.
Norton v24 appears to allow access to Settings from Standard user account with Sign In to Admin user.
IDK why your Settings are not working.
Were my machine. Iād Sign out / Sign in Nortonā¦as test.
and Restart (not Shut down) machineā¦as test.
No difference.
No difference.

Done. No difference. (Although I did notice that during the time when Norton was uninstalled, the problems Iāve been having recently with my mouse severely lagging when I launch Firefox suddenly went away. All this time Iāve been thinking that was a Firefox issue or a Windows 11 24H2 issue, and it was actually a Norton issue.) (Also while Norton was uninstalled, the program that Norton had been blocking worked fine, of course.)
-
Done. Useless. The brain-dead chat agent wasted 25 minutes of my time doing absolutely nothing, until he finally made a suggestion that I add the program that is being blocked the the virus scan exclusion list. Apparently the agent doesnāt know the difference between virus scan and firewall. (I also tried phone support. I was on hold for 40 minutes ā of the promised ā5-minute estimated wait timeā ā before I hung up.)
Is there a way to revert to an older version of Norton, that didnāt have this issue?
For now, Iām giving up and disabling Smart Firewall. Iāll rely on Windows Firewall, plus Norton Anti-Virus. (Will Norton give me half my money back since theyāve made half their program unusable? No, I know they wonāt.)
To add insult to injury, now I canāt even activate the reinstalled Norton 360. I keep getting this error message when I enter my valid login credentials:
Is there nothing this company can do right?
I should have specified: Is there a way to revert to an older version of Norton, without downloading software from sketchy unofficial websites?
what websites are sketchy unofficial?

I used Wireshark to track
- Cast Win 11 to TV
- working (NORTON Firewall OFF) vs
- not working (NORTON Firewall ON).
There were clear differences in the network traffic.
Working case
- see IGMPv3 protocol messages
NOT working case
- no IGMPv3 protocol messages
I could not find any NORTON 360 Firewall documentation relating to IGMPv3.
Maybe somebody at NORTON could take a look at this.
I did this, and my Public enetwork exceptions screen now has both Public and Private networks enabled to Allow IGMP traffic. But ā¦ no joy!; still doesnāt work!
To the Norton Support Team: WTF! This has been dragging on for months, and I actually spent 1 hour with a support person ā given him remote access to my computer ā but after 1 hour of poking around at seemingly random (to me) options it still wouldnāt work. Since this is trivial to replicate, what kind of a software business are you guys running there??? This is not a āsubtleā difficult-to-replicate issue. Your crap just no longer works as it did before. So you wonāt fix it or you canāt fix it (layed off everyone who actually knows how your sotware works)?
In Norton 365 I did
Home ā Settings ā Troubleshooting ā Reset to default ā Yes, reset
Canāt be sure what this changed for me.
Cast to TV now works with Norton Smart Firewall ON.
I did notice in Smart Firewall traffic rules there are
- two entries re MULTICAST
- I am not sure if these were both there before I did the reset.
Be aware the reset will remove any settings you have made.

Thanks for yet another possible solution, BUT I tried this RESET, then rebooted and still cannot cast.
It works for meā¦thanks a lot !!

It did not continue to work for me.
So what I didā¦
Got ready to replicate the problemā¦
- got TV ready to accept wireless mirror of PC display
Then get set up to record Norton logs that capture the problem
Settings ā Troubleshooting ā Enable debug logs ā Send logs (this starts recording the logs)
Then attempt to
- Cast PC display to the TV
It will capture the logs and by default will automatically send them to Norton.
I did this one day ago and was surprised to find that next day
- Cast to TV was working again

It has stopped working ! I give up.
In my case (having tried all of the above - and some more), it appears that the only way to get CASTing to work on my TV, is to disable the Smart Firewall 
I have tried adding traffic and app rules for different EXEās and checked the rules for both PUBLIC and PRIVATE IGMP traffic. I have also set the configuration to allow IGMP traffic on both PUBLIC and PRIVATE. Alas!
Sad to sayā¦me too. I have to disable the firewall.
