We currently are testing 3 Windows 7 Professional PCs in our network. We are able to browse to WinXP, Win2k3, and Win2k8 machines from these PCs just fine. However, when we attempt to browse to the Windows 7 PCs (from any of these operating systems, including the other Windows 7 PCs) we aren't able to. We either get an authentication box (we actually only get this from the other Win7 PCs, but nothing we type in works), or it says the resource can't be found. We've turned on everything except network discovery on all 3 PCs - for some reason network discovery will not stay on. Any suggestions are appreciated.

Hi, Based on my research, I would like to suggest the following: 1. When you are prompted to input the credential, please try the following accounts: 1) The administrator account of the Windows 7 computer 2) The domain administrator account 2. On the Windows 7 computer, go to “Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings” and ensure that the following items are turned ON: Network Discovery File and printer sharing And this one is OFF: Password protected sharing 3. Temporarily disable or remove all the security software (firewall, anti-virus, anti-spyware, etc.) on the computers and check if it works. Hope this helps. Thanks. Nicholas Li - MSFT

Forgot to mention, this is a domain environment. 1. Ok, I tried these two accounts (along with about half a dozen others) and it doesn't work 2. Network Discovery - as I mentioned before, this will not stay on. *edit* Ok, I got this to turn on by enabling the SSDP service. Same results. File and printer sharing - this is on Password protected sharing - I don't see an option here for this...it's my understanding that this option is not available for PCs on a domain. 3. Ok, tried this, and we still get the same result.

Anyone have any ideas? This issue is crippling our migration efforts.
