SCCM SUP sync failed 6703

May 17, 2011 - ConfigMgr/SCCM, Uncategorized

Today I have been searching to get the SUP role running in SCCM ’07 R3.  doublechecking ports and proxy settings did not advance me much.

the thing is the initial synchronization kept on giving error 6703: UssCommunicationError: WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. —> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to .
 Source: Microsoft.SystemsManagementServer.SoftwareUpdatesManagement.WSyncAction.WSyncAction.SyncWSUS.
  The operating system reported error 2147500037: Unspecified error

windowsupdate.log: cached cookie has expired

making sure the SCCM server was not applying the GPO with the ‘regular’ WSUS settings enabled.

when I tried to check for updates on the server I kept recieving the message : error 80072f8f or better 80072efd

solution: went to and downloaded/installed the rootsupd.exe on my sccm server. after that I was able to check for updates on the server itself and the sync finally started

can’t remember completely how I got to that point..

Problem solved!
