Few systems gettting windows patches from Microsoft in place of WSUS

Hi,
We have WSUS in place but few systems downloading patches directly from microsoft in place of WSUS which choke our internet bandwidth. We have checked WSUS group policy on those systems and its publishing properly.
Please help on this.

Use GPresult on one of the clients that has the problem or use the Results wizard in the GP Management tool to find which polices are actually being received by the client

Does running from command prompt <<<on these systems
 
reg query "HKLM\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate"
 
confirm they are pointed to your WSUS server ?

Also on your WSUS server,  is it configured to store updates locally ?

Log onto the WSUS server and start the WSUS console, select OPTIONs from the panel on the left, Select Update Files and Languages

... I dont think this is the problem if only SOME machines are using MSUPDATE.

pdixit1977Author Commented:
yes, i cheked and found correct registry entry.
 
DonNetwork AdministratorCommented:
Ok, what is it that makes you believe that they are getting their updates from Microsoft and not your WSUS server ?
pdixit1977Author Commented:
I dont know thats why i am here. My network team reports me daily @ 9 AM that heavy downloading is occuring on network from microsoft IPs. Usually this happen if WSUS GP is not applying but checked and found it correct. we have 520 number of total systems and 483 systems are appearing in my WSUS console. Difference is normal because few systems are dead and few connects to client network directly.  
I was looking on a system on which GP was correct, registry entry was also correct but that systems was downloading 18 patches directly from microsoft and that was happening in front of me so i am confused why this abnormal behaviour is happening.
