WSUS best practice for deployment

Hi Guys, we have limited OU's in our environment and will not be extending this. Therefore would is it possible, and is it best practice to apply the computers to security groups and attach this to a GPO?

thanks

It's not best practice, but it isn't looked down on either.  What I would do instead of what you're thinking is to use Security Filtering, and WMI Filtering.  Check this out:

(it's for 2008, but still applies to 2012)

And again, Security Filtering would be the way to go.  WMI is more for if you need to target an OU with a GPO but only want Operating System X (where x is the operating system you want to focus on) and not Operating System Y to get the settings.

For what you need, simply add your computers to the groups they need to be in, then apply the GPO to the OU you want, and use Security Filtering to apply or deny whatever you like.

For reference:  http://www.techrepublic.com/blog/the-enterprise-cloud/group-policy-object-filtering-by-security-group/

This is a simple, but good, place from Microsoft to start:  http://technet.microsoft.com/en-us/library/cc752992.aspx

The great thing about security filtering is it is perfectly fit for the problem you described where you only have a certain number of OUs and you can't create more or you can't do a lot of changing things around because it allows you to apply a Group Policy Object to an OU/Container but not have it apply to everything in that container.  That's where having your computers/users in the right security groups really helps.

Hi Brad, would i be able to attach the GPO to an OU, add the security group to the GPO but have the Computer in a differnt OU?

Brad BouchardInformation Systems Security OfficerCommented:
You have to have the users/computers either in the OU where the GPO is applied, or have it applied to the whole domain.  Reference:  http://serverfault.com/questions/178183/group-policy-not-being-applied-unless-user-is-in-ou

If that doesn't make sense here is a screenshot to illustrate where you would put the OU.
gpo
What you would do is create a security group for the computers you want to have your settings applied to and add the computers to it, then you attach/link the GPO to the entire domain at the top of the list (from screenshot above), after that, you would use Security Filtering and only add the Computer Security Group you created to apply it to as described in this link:  http://www.edugeek.net/forums/windows/112614-apply-group-policy-ou-but-exclude-certain-computers.html

If that doesn't make sense let me know and I can elaborate more, but I'm quite certain if you follow those steps you'll see what I mean.

Thanks Brad, thats clarified it for me. So essentailly if i have all the computers in one OU and would like 4 different setting to be applied, i would have to attach all the GPO's to that single OU

Brad BouchardInformation Systems Security OfficerCommented:
Yes, or just simply attach the GPO to the entire domain and in the Security Filtering section only apply it to those 4 computers.

No problem my friend, any time.

One last thing, do you use a reboot script for your clients and servers?

Brad BouchardInformation Systems Security OfficerCommented:
I don't personally, but I'm sure there are many who do.

Also, just so you're aware too there isn't any problem with this question but I did request Administrative Assitance so we could actually mark the answer as my comment (ID: 40008780) instead of the one you marked.  More for reference than anything so that if someone else sees this question they know exactly what finally worked.

Glad we could get you a solution, hope to see you around here again soon.
