How to disable SMB2 and SMB3 from clients

There are many programs that are using a shared file on the server from clients from XP to Windows 10. From time to time it seems like there is a network outage and the handle to the file is broken and the file

cannot be read or updated. It seems more prevalent on a Windows 2012 server but may have happened from time to time on 2008 & 2008 R2. However there are not any network problems so it just leaves the server & Client

I have searched for possible resolutions including:-

• Turning  off the Cache for the share
• Disabling the network adapter power setting to allow windows to put the device to sleep.
• Disabling  Antivirus/configuring it to ignore folders for on access scanning
• Disabling SMB  Signing
• Configuring the  clients DWORD registry value SilentForcedAutoReconnect=1 in HKEY_LOCAL_MACHINE\Software\Microsoft\CurrentVersion\NetCache
• Setting the "NET CONFIG SERVER /AUTODISCONNECT:-1" to not drop client

connections

The last bit of trouble shooting that I can think of is to disable SMB2 and SMB3 as that does a lot of caching and batching of packets which could also be the cause of the problem.

I have looked at http://support.microsoft.com/kb/2696547/en-us

I have disabled SMB2&3 on the server as that is very straight forward.

When I get to the section about disabling SMB2 on the client the command fails.

sc config

lanmanworkstation depend= bowser/mrxsmb10/nsi

  After running the above command, it returns an error: 

      [SC] ChangeServiceConfig FAILED 1059:

      Circular Service Dependency was specified.

So it's not worth running the following command:

sc config mrxsmb20 start= disabled

I have tried the command on Windows Vista, Windows 7 and Windows 10 just to confirm that it's  nothing to do with any particular PC, machines in Domains and Non-Domain machines.

So, my questions are:-

1, is http://support.microsoft.com/kb/2696547/en-us actually correct and up to date and for the OSes (Vista, 7, 8, 8.1, 2012 server and Windows 10) with latest updates & service packs?

2, How do I disable SMB2 and SMB3 on clients for troubleshooting purposes the server to resolve problems with shared files (multi user access)

Thanks in advance
