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.

 https://support.microsoft.com/en-us/kb/2720211

 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)
  • http://www.microsoft.com/en-us/download/details.aspx?id=29999
  • 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
  • https://support.microsoft.com/en-us/kb/2734608
  • 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
