Clients not installing updates from Downstream WSUS Server

-

hello,

this first post in technet, new administrator please bare me. initial setup follows:

upstream wsus server named bak-wsus1, downstream server name atl-wsus1; atl-wsus1 replica. have made wsus servers site based through gpos named wsus(bakersfield), wsus (atlanta), remote sites , computers added wsus (atlanta) gpo , report atl-wsus1 server should, same true wsus(bakersfield) computers.

every computer joined wsus(bakersfield) gpo reports bak-wsus1 server (as stated) , receives updates approve them, however, approved updates not install on computer reporting atl-wsus1 server. when checking reports on server shows sites "approved install" computers "not installed". 

i have forced remote clients wuauclt /resetauthorization /detectnow. when checking downstream server status shows following: 

mode: replica installed/na: 0% last synchronization:(today). servers infact syncing, downstream server has files install, or atleast thats file status says. 

any , suggestions, help, comments, appreciated, have been crawling every related forum past couple of days.

thank you.

lawrence,

thank help, infact duplicate susclientid issue. here solution:

cmd window net stop wuauserv

regedit hkey_local_machine\software\microsoft\windows\currentversion\windowsupdate

delete subkeys susclientid, susclientidvalidation

cmd window net start wuauserv

wuauclt.exe /resetauthorization /detectnow

the /resetauthorization switch re-issues susclientid , validation

thank again lawrence.
