Api Remoting Configuration

The API Remoting service is not working correctly. This may be because of configuration issues.

Possible resolutions include:

  • First, troubleshoot any issues with SQL Server before proceeding.
  • Troubleshoot any general issues with IIS.
  • Check permissions.
    1. Open a command window.
    2. Type cd <WSUSInstallDir>\WebServices\ApiRemoting30
    3. Type cacls
    4. The following ACEs should be set:
      • NT AUTHORITY\NETWORK SERVICE:(OI)(CI)R
      • BUILTIN\Users:(OI)(CI)R
      • NT AUTHORITY\Authenticated Users:(OI)(CI)R
      • BUILTIN\Administrators:(OI)(CI)F
      • NT AUTHORITY\SYSTEM:(OI)(CI)F
  • Check the IIS configuration of the reporting web service using the IIS script adsutil.vbs (or use the IIS Administration UI Tool).
  1. Open a command window.
  2. Locate the adsutil.vbs tool, which is typically in <InetpubDir>\AdminScripts.
  3. Locate WSUS virtual directories on the IIS server: type <InetpubDir>\AdminScripts\adsutil.vbs find path
  4. Find the path of the ApiRemotingWebService (it will look like W3SVC/<WebSiteID>/ROOT/ApiRemoting30).
  5. Get the properties of the Web service: type <InetpubDir>\AdminScripts\adsutil.vbs enum W3SVC/<WebSiteID>/ROOT/ApiRemoting30
  6. Compare the output with typical values below (this is a partial list): KeyType:”IIsWebVirtualDir” AppRoot:”/LM/W3SVC/<WebSiteID>/ROOT/ApiRemoting30″ AppFriendlyName:”ApiRemoting30″ AppIsolated:2 Path: “<WSUSInstallDir>\WebServices\ApiRemoting30″ AccessFlags:513 AccessExecute:False AccessSource:False AccessRead:True AccessWrite:False AccessScript:True AccessNoRemoteExecute:False AccessNoRemoteRead:False AccessNoRemoteWrite:False AccessNoRemoteScript:False AccessNoPhysicalDir:False AspScriptErrorSentToBrowser:False AspEnableParentPaths:False AuthFlags:21 AuthBasic:False AuthAnonymous:True AuthNTLM:True AuthMD5:True AuthPassport:False AppPoolId:”WsusPool”
  7. Type <InetpubDir>\AdminScripts\adsutil.vbs enum W3SVC/1
  8. Compare the output with typical values below (this is a partial list).
  9. KeyType:”IIsWebServer” ServerState:2 ServerComment:”Default Website” ServerSize:1 ServerBindings:”:80:” SecureBindings:”:443:” ConnectionTimeout:180 DefaultDoc:”Default.htm,Default.asp,index.htm,iisstart.htm” AspBufferingOn:False LogPluginClsid:”{FF160663-DE82-11CF-BC0A-00AA006111E0}” Win32Error:0 AppPoolId:”DefaultAppPool”

  10. Type <InetpubDir>\AdminScripts\adsutil.vbs enum W3SV
  11. Compare output with typical values below. This is a partial listing. For more information, see “Appendix C: IIS Settings for Web Services” in the WSUS 3.0 Operations Guide at http://go.microsoft.com/fwlink/?LinkId=81072  KeyType:”IIsWebService” MaxConnections:4294967295 AnonymousUserName:”IUSR_<machinename>” AuthFlags:1 AuthBasic:False AuthAnonymous:True AuthNTLM:False AuthMD5:False AuthPassport:False AppPoolId:”DefaultAppPool” IIs5IsolationModeEnabled:False
