SCCM WSUS sync error – Sync Failed – WSUS server not configured

-
Consider the following scenario

  • The WSUS is installed on SCCM central site server.
  • The correct port is configured in Software Update Point setting.
  • No proxy server is in used.
 I was getting following error in WSysncmgr.log file when initiating synchronization from Configuration Manager console.

Sync failed: WSUS server not configured. Source: CWSyncMgr::DoSync

STATMSG: ID=6703 SEV=E LEV=M SOURCE="SMS Server" COMP="SMS_WSUS_SYNC_MANAGER" SYS=SERVER1 SITE=BNG PID=1728 TID=3408 GMTDATE=Sat Apr 03 18:28:48.292 2010 ISTR0="CWSyncMgr::DoSync" ISTR1="WSUS server not configured" ISTR2="" ISTR3="" ISTR4="" ISTR5="" ISTR6="" ISTR7="" ISTR8="" ISTR9="" NUMATTRS=0

I have gone through lots of articles but nothing worked for me. I have also verified the configurations as described in the TechNet article. Everything was fine.

Later I noticed the following error in wcm.log.

System.Net.WebException: The request failed with HTTP status 401: Unauthorized.~~   at Microsoft.UpdateServices.Administration.AdminProxy.CreateUpdateServer(Object[] args)~~   at Microsoft.UpdateServices.Administration.AdminProxy.GetUpdateServer(String serverName, Boolean useSecureConnection, Int32 portNumber)~~   at Microsoft.SystemsManagementServer.WSUS.WSUSServer.ConnectToWSUSServer(String ServerName, Boolean UseSSL, Int32 PortNumber)
  
The same time following error was appearing in the IIS log.

2010-04-03 19:06:44 W3SVC1 192.168.1.101 POST /ApiRemoting30/WebService.asmx - 80 - 192.168.1.101 Mozilla/4.0+(compatible;+MSIE+6.0;+MS+Web+Services+Client+Protocol+2.0.50727.42) 401 1 0

I searched for the error which was in IIS log and come to know about below article on MyITForum.com.

The method 1 described in the http://support.microsoft.com/kb/896861 worked like a charm.

Method 1
To set the DisableLoopbackCheck registry key yourself, follow these steps:
  1. Click Start, click Run, type regedit, and then click OK.
  2. In Registry Editor, locate and then click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
  1. Right-click Lsa, point to New, and then click DWORD Value.
  2. Type DisableLoopbackCheck, and then press ENTER.
  3. Right-click DisableLoopbackCheck, and then click Modify.
  4. In the Value data box, type 1, and then click OK.
  5. Quit Registry Editor, and then restart your computer.

Managing Endpoint Protection client with Command Line Interface – MpCmdRun.exe The MpCmdRun.exe (Microsoft Antimalware service command line utility) is very useful tool to manage local Endpoint protection client with command line.  The MpCmdRun.exe is located in C:\Program Files\Microsoft Security Client folder.

When executed, this command automatically creates a log file named as MpCmdRun.log in C:\Users\ username\AppData\Local\Temp folder. This log file records the commands that are executed using MpCmdRun.exe. Few of most commonly used command lines are listed below. For a complete l list of availa
