Windows 7: Windows 7 Network Discovery Issue

Windows 7 Network Discovery Issue

I'm unable to get my network discovery working. This is preventing me from connecting to my homegroup and even my printer. I can ping the other computers and devices on my network, I just can't connect to them.

Here are all the services currently running.

(Edit: At some point, my workgroup changed back to the default. Unsure as to what could have caused this. Also, it seems Windows Firewall was preventing me from connecting to my homegroup and my printer, so it's off now.)

Problem fixed.

There are various solutions to fix this problem but turning off Windows firewall is definitely not one of them. Turning off Windows firewall leaves your system open to attacks and is something that should never be done under any circumstance.

We can assume that you have network discovery turned on in the Advanced Sharing Settings window. This is a fairly common problem by the way.

Network Discovery will not stay on or enabled. - Microsoft Answers

Others have fixed the problem by doing this:

I went to Control Panel -> Administrative Tools -> Services. I found that SSDP Discovery service was set to "Disabled". I haven't had any reason to change services, so apparently it was set that way by default. After setting the service to "Automatic" and starting it, I was able to set Network Discovery to "on" successfully.

Also make sure to Turn on DNS Client, Function Discovery Resource Publication, SSDP Discovery, and UPnP Device Host services.

I have in fact tried both those solutions, along with several others that I have researched, hence why the first thing I did was post the services that I have running.

The network discovery would not stay turned on in the Advanced Sharing Settings, nor would it stick when I clicked the drop-down warning that would occur after clicking on the "Network" link in the file manager

Have tried running the sfc/scannow command to see if there are any file integrity problems?

You will most likely find problems there if you can't turn on Network Discovery.

Ok good, I believe I found another possible cause as I have tracked this same problem down in the past.

Can you please post a screen shot of the ipconfig/all from this machine?

Ok thanks, just as I suspected. You have a bunch of 6 to4 adaptors there that can cause this problem, this has cause the exact problem you have in the past.

You will need to remove all those extra tunnel adaptors and also disable any virtual adaptors that you aren't using.

This .exe file will remove those extra adaptors for you. Save the file, unzip then right click either the 64 or 32 bit version "depending on your system" and run as admin. Ignore and override any warning messages you receive. After the file runs reboot your machine.

Be sure to enable the Windows firewall then check to see that most of the 6 to 4 adaptors are gone, there should only be a couple of those, then check to see if you can turn on network discovery.

Ran it, it said it removed 1. Turned my firewall back on to recommended settings and now my homegroup is no longer working. Network discovery is on now.

Here is the ipconfig now.

For anyone else with this problem where Network Discovery won't stay on.

The problem is that the base filtering engine requires a repair, it was most likely caused by a virus.

Pay no attention to the stuff saying check to see if the base filtering engine is missing etc. If the Network Discovery won't stay on then you have to run this repair, no doubt about it.

To repair the base filtering engine click on the link and follow directions.
