Norton Internet Security / Norton AntiVirus

[J42]

I am wondering if there is a way to make a Homegroup work without uninstalling NIS 2010.

I am trying to set up a Homegroup with my 2 computers: 1 with Windows 7 Ultimate (64 bit), 1 with Windows 7 Home Premium (64 bit).

Both computers have NIS 2010.

I have opened the Network Security Map in NIS and set the Trust level to Full Trust.  I have done this on both computers.

I have tried creating Homegroups with both computers, but when I create aHomegroup on 1, the other can't see it, so I don't get the option to join the Homegroup.

Do I have to uninstall NIS on both computers, set up the Homegroup, then reinstall NIS 2010, or is there a way to set things up without uninstalling?

Thanks in advance for any advice.

Hi J42,

Welcome to the Norton Community.

What is your full version of NIS 2010 from Help & Support > About?

Have you double checked to make sure that the Windows Firewall is OFF? Having two firewalls active will cause problems.Do you have any other security software (anti-virus, etc) installed in your computer besides NIS?

What type of home network do you have? Is it wired, wireless, etc?

Have you tried completely disabling the NIS firewall on both computers to see if this corrects the issue? You can toggle the Firewall off from the main NIS window where it says Smart Firewall.

If this does not correct it there may be something else going on but this would be the place to start to confirm if this is a firewall issue.

Thanks for your response and for welcoming me.

NIS 2010 version: 17.7.0.12 (both computers)

Windows firewalls are off on both computers, and there are no other security programs on either computer.

Network is wireless. (TRENDnet TEW-652BRP router)

I tried turning off the NIS firewalls with no success.

Windows Troubleshooter identifies the problem as NIS.

Thanks again.

Hi J42,

Thanks for the update. Please take a look through this thread and see if anything appears relevant to your situation.

I have a wireless home network currently with Vista Ultimate on my main desktop + 2 laptops, one with Vista Home Premium 32 bit and the other with Windows 7 Home Premium 64 bit and no problems. Also have a shared network aware printer which is connected directly to the router and a couple of other misc. devices. No problems across the board, so I know that NIS should work in this environment just fine. The Windows 7 laptop was added after NIS was already set up and it pretty much worked out of the box.

I would also recommend checking your router configuration closely. Is your router firewall turned on? If so I would recommend turning it off for a test also.

When I first upgraded to wireless N network from G I had purchased a Cisco router where the firewall was causing all sorts of problems with connectivity. I found out lo and behold I could not turn off the router's firewall (directly from Cisco support!) so I ended up going with a Netgear router and had no problems at all.

It is OK to use a router firewall along with a single firewall on your computer but this does illustrate that routers are sometimes prone to causing connectivity issues because of the built in firewall.

As a test you could also try temporarily setting up your computers through a wired connection into the router. If this works then you know it has something to do with the wireless aspect of the network and it gives us an area to concentrate on.

Hope this helps.

Thanks

The troubleshooter may just be responding to a firewall block and assuming that Norton is the culprit.  Both machines should be listed in the router settings.  It should identify each machine by the MAC address. You may have to check with your ISP if you are unable to llist more than one device.  I had to upgrade my service before I could use multiple devices.
