I don't know when or how it happened but my home workgroup stopped working correctly. The thing that has me baffled about it is the problems are only with my main installation of Win7Ult on my desktop. There are 6 devices connected to an Asus router, 3 are wired 3 are wireless. All show up and work correctly except when in my Win 7 Ult HD. When I boot to the Win 7 Prem OS on the same desktop without changing anything it works fine. Have looked around but can't find a away to re-configure this piece of the workgroup. I have tried everything I can think of. Please can anyone help me!
It may not be a workgroup issue, but a homegroup one - Windows 7 uses a "homegroup" thing that's sort of like pseudo-domain; to join it requires the password that was created when the network was first set up. Just a hunch, but it may be worth checking on that - I can't recall off the top of my head how to get to that though... but: http://windows.microsoft.com/en-us/windows7/products/features/homegroup
Not sure what all you have tried, so...what results from running the "HomeGroup troubleshooter"? Control Panel/Network and Sharing Center/HomeGroup/Start the HomeGroup Troubleshooter Again, you may have tried this but - "Leave the HomeGroup"...then re-join? Sorry if you have already tried these things, but you never know...
Workgroups functions on a layer of NetBIOS over the TCP/IP protocol. Sometimes there can be problems with connections if NetBIOS isn't enabled such as not being able to connect to the workgroup or access remote folders, printers etc. You should make sure that connection settings hasn't had netbios disabled. https://marjanrepic.wordpress.com/2011/07/05/disable-netbios-over-tcpip-in-windows-7-ent/
