Windows 10 1511 Network Browsing Issue

spapakons said:

Is network discovery enabled in Advanced Sharing Options? Are all the relevant services running (not remember which right now) ? I don't know if this help, but maybe you should disable password sharing.

Advanced sharing is enabled for domain computers and the appropriate services are running. PW sharing not present in domain.

I have a WIndows 7 Professional x64 VM, which I occasionally use for testing.

It was able to see all the systems on the network. But today I installed a lot of updates (I guess about 6 months of those) and surprise: it can no longer see the other systems.

It seems to me that MS was so proud of an "enhancement" in Windows 10, that they back ported it to Windows 7.

I am not going to find out which update causes the problem.

Looks like there is issue here. Since it involves network browsing, finding a fix should be high priority for Microsoft. This type of problem is great way to bother IT managers of big organization trying out windows 10. We can hope that network objects will magically appear on network browsing. Sooner would be better than later.

*SOLUTION*
I discovered that my server on the network had defaulted to smb2. I changed the server to smb1, and yikes everything appeared under Network in Win 10 Pro 64. It seems any networked computer not on smb1 will cause all network browse to fail.

Still not fixed after last updates.

OK, I don't know much about SMB versions (if anything). But I could not find anything in the registry of both my Windows 2012 R2 server and the Windows 10 1511 client which could indicate what SMB version is being used.

Could someone please elaborate on this? Which registry keys are involved here?

Thanks in advance!

To obtain the current state of the SMB server protocol configuration, run the following cmdlet:

Code:

Get-SmbServerConfiguration | Select EnableSMB1Protocol, EnableSMB2Protocol

Run in PowerShell as Administrator

For the Win10 client run this is PowerShell Command Prompt:

Code:

sc qc lanmanworkstation

Unless you've messed with it one of the dependencies should read as "MRxSmb20"
Edit: My apologies: In the Win10 client that should be run in Command Prompt not PowerShell.

I have a Synology server. In the server Control Panel under File Services/Advanced Setting/Max Protocol for Windows File Service/Dropdown box SMB1,2, or 3. It defaulted to SMB2. I chose SMB1 and the Network reappeared in the Win 10 desk top. Hope this helps you.

OK, thanks. Now I have seen that when I disable SMB2 on my server, the network neighborhood on my Windows 10 system reappears. So it seems that SMB2 on Windows 10 1511 is broken.
