We have local WSUS server which has version:3.2.7600.226. Some window workstation has update agent (7.5.7601.1751) working fine but some workstaion has update agent with latest version(7.6.7600.256) can not search new update on WSUS server. And the error code return 800B001 .So for solution for this case should we update WSUS server to newer version or there is anyway to downgrage window update agent version ? Below is windowsupdatelog as i have recently .
Any advice for this ?
Thank you
