Wsus client windows 7 not reporting in WSUS 3.0 SP2

[LAMONT D]

As mentioned in title my windows 7 client has stopped reporting in my wsus server, i have total 7 clients and none of them report. Don't know what's wrong, i just want to sort it out as soon as possible?? Can anyone let me know what might be causing it so that i can look out for troubleshooting related to it?? Any help regrading this will be appreciative.

Its hard to guess the cause of the issue like that as there are different causes for this issue. I will suggest you to run Client Diagnostic Tool and check out WindowsUpdate.log. If you find anything suspicious in WindowsUpdate.log. then post it here so that i can have better idea of the issue you are going through. You can also try stopping Automatic Updates service, renaming %windir%\SoftwareDistribution folder to SoftwareDistribution.OLD and restarting Automatic Updates service. Just take backup of your current directory before trying the changes ive mantioned.Best of luck.
