WSUS - errors 800B0001 on clients from 2008/2012 server with Wsus role KB2720211

I had clients and server that was trying to download patches from Windows 2008/2012 R2 WSUS server.

Inside c:\windows\windowsupdate.log I got this error:

Agent WARNING: WU client failed Searching for update with error 0x800b0001

To solve this issue I applied this Microsoft article that talk about patch to be installed on Wsus server.

Update for Windows Server Update Services 3.0 SP2 (KB2720211)

DownloadDownload the package now.

Update for Windows Server Update Services 3.0 SP2 for x64-based Systems (KB2720211)

DownloadDownload the package now. 

Verbosely Procedure:

1. Install this patch on wsus server
  • Download and run Update for Windows Server Update Services 3.0 SP2 for x64-based Systems (KB2720211)
  • After the hotfix is complete, Stop your WWW Service
  • Stop you UPDATE SERVICES Service
  • Perform an IISRESET (which seemed redundant to me, but it does start the WWW service)
  • Start your UPDATE SERVICES

2. Install this patch on Wsus server

  • Issues that are fixed
  • This update lets servers that are running Windows Server Update Services (WSUS) 3.2 provide updates to computers that are running Windows 8 or Windows Server 2012.

if c:\windows\windowsupdate.log on Windows 2012 R2 you view this raw:

WARNING: Failed to get Network Cost info from NLM, assuming network is NOT metered, error = 0x80240037

 open the "local group policy"
    expand  local computer policy -->computer configuration -->windows settings -->security settings --> network list manager policies
    in the right pane you will see Unidentified Networks , double click it , then you can configure theLocation Type when the network connection is unidentified
    If there is domain , you need to change the same entry in "Domain Policy"
    after that please restart your computer
