Windows 7: No Networks to Connect To (Very Weired)

Greetings,

I have gone through most of the posts on this forum that talk about Networks and Connectivity, Homegroups connections, and nothing addresses this problem.

I have had Homegroup established on both my desktop and on my notebook both running Windows 7 ultimate build 7100 for months. Surprisingly; few days ago, my notebook ceased to see the Homegroup and my Network and Sharing Center says that the notebook is currently not connected to any network even though the notebook is connected to the network and can use the Internet.

Homegroup and public group and unidentified group all disappeared on my notebook but working well on my desktop. I have done all the suggestions on other posts (i.e. leave Homegroup reboot, establish new one, passwords) you name it, I tried them all. The groups do not show as you can see in the attached picture. I tried IPv6, I tried the Homegroup listener in the Services. I tried about everything.

Both desktop and notebook connect to my ADSL router wifi.

Has anyone been through this problem? Greatly appreciate your input.

- Edit: I found out that the PNRP service is disabled, normal, but it will not start, when I start it I receive "Access Denied" error. Any suggestions?

- Problem Fixed: I reinstalled Windows 7.

Thank you.

Have you made sure that the time on all of the machines are EXACTLY the same. Even if it's 1/2 second difference it won't connect!

Thank you rsvr85 for visiting my post, yes I checked both computers and the time is the same.

Did you check the HomeGroup Provider service?

Yes, both Homegroup services start automatically and are started with no luck!!!!
