Ensuring that group policy is applied before logon
By default group policies are applied asynchronously - Fast Logon Optimization . The upshot is that if you update a policy users may logon before the latest policy is applied and it may take a couple of logons before current settings are applied.
I am messing about with GPOs in a test environment so I don’t want to have to constantly rebooting PC or perform multiple logons attempts.
Disable Fast Logon Optimization by using the following
Create or update and existing group policy attached to the OU housing the computers and edit the following.
Computer Configuration
Policies
Administrative Templates
System
Logon
Enable: Always wait for the network at computer startup and logon

User Template increase attributes copied
When you create a user template and copy it to create a new user only a limited number of attributes are copied
Example: Copy Office From the General tab
Suppose you have a user template and want the Office value from the general tab to remain when you create a new user by copying the template.
You can use ADSI Edit to make the attribute copy.
- Open ADSI Edit
- In the left pane right click ADSI Edit and Connect To the Schema Naming Context
- Locate the attribute name in this case Office is:
Physical-Delivery-Office-Name - Right Click and open Properties
- Attribute Editor Tab … locate searchFlags
- Edit and add 16 to the value
- To prevent it from copying remove 16 from the value.
I have tested with Windows 2008 R2 as shown but certain it should work with previous version as I learned from a Windows 2000 KB Article.
Where do you get the attribute names … I found some here.

Active Directory Shadow Groups
Simply: You have an OU in active directory … add any user accounts in the OU to a group … in addition you want to maintain the membership when accounts are added or removed from the OU.
The following link includes examples using the ds* commands and PowerShell to populate and maintain Shadow Groups.
Shadow Groups in Active Directory
It should be possible to expand these examples to include the user accounts from other OUs or to use Identity Attributes rather than OU.

Update GPO templates to manage Windows 8
You’ve added some Window 8 PCs and possibly Windows Server 2012 to your existing Windows Server 2008 R2 enterprise … okay so how do you access the additional features with Group Policy?
Looking at a Group Policy setting in Windows 8 Windows 8 GPO Blocking Connection Accounts … I got to thinking … I’m doing this from Windows Server 2012 … more realistically I will be adding Windows 8 machines to a Windows Server 2008 environment.
How do I update the group policy template files?
My only caveat … I have still to do the testing … will the new templates work with the old admin tools.
Windows 7, Windows Server 2008 R2 Group Policy Central Store
Administrative Template files for Windows 8 & Windows Server 2012

Certificate Services Installing CA
The preferred method
Microsoft best practice is to install a standalone root CA with an enterprise subordinate CA. The Standalone can then be isolated offline for enhanced security while the subordinate takes over issuing certificates.
The following videos gives a short demo of installing two CAs using server 2003 … it is a good starting point for his 2008 videos.
Microsoft CA 1 of 2 - Setup Standalone Root
Microsoft CA 2 of 2 - Enterprise Subordinate
The following video gives a short demo of CA autoenrollment using server 2003.
Microsoft CA - Autoenrollment Step-by-Step
In reality a single tier
While it is best practice to have two CAs … see above … in many instances you may only have one server at your disposal.
Single Tier PKI one CA that does all the issuing of certificates aimed at small business of up to 300.

TechNet: Test Lab Guides
Test Lab Guides (TLGs) allow you to get valuable hands-on experience with new products and technologies using a pre-defined and tested methodology that results in a working configuration. When you use a TLG to create a test lab, instructions define what servers to create, how to configure the operating systems and system services, and how to install and configure any additional products or technologies.
A challenge in creating useful TLGs is to enable their reusability and extensibility. Because creating a test lab can represent a significant investment of time and resources, your ability to reuse and extend the work required to create test labs is important.

Check firewall not blocking shared printing
Couple of quick ways to check if the firewall is blocking a shared printer.
From a remote machine open an command prompt and use
Net View \\print-server-name
This should return a list that includes the name of the shared printer generally you can now eliminate the network or firewall as an issue.
or download PortQry from Microsoft and check the required ports are open on the computer sharing the printer.
Use PortQry or PortQueryUI to check TCP ports 445 & 139
If computers are not on the same LAN segment don’t just check the print server firewall ensure their is not another firewall between the computers.

Print spooler must be running on server and client
Read something like this … “In order to print to a server based printer the print spooler must also be running on the client” … time to experiment … It is the same with a Remote Desktop session and a locally attached printer?
Did an experiment, I used Remote Desktop from a Window 7 machine to a Windows 7 VM. Remote Desktop is setup allow the remote session to use the local printer.
Succeeded in printing from notepad on the remote machine to the redirected LaserJet on my local machine.
Shut down the spooler on the remote session with
net stop spooler
and tried to print from notepad got this error and
everything disappeared the from Select Printer except Add Printer
restarted using net start spooler
all the printer came back.
Remote/Shared printing … the spooler must be running on both machines not just the box the printer is plugged into.

Rearm Windows 2011 SBS Evaluation
Something always comes up when you are trying to evaluate a product and X weeks/months later you fire up the virtual machine and the Grace Period has expired.
slmgr.vbs –dli will tell you how long the grace period is.
slmgr.vbs –rearm will reset it.
I have tried this on a couple of product the latest being an evaluation version of Small Business Server 2011 and the grace period was reset to 30 days.
If memory serves me then it should work for Windows 2008 evaluations.
Don’t know if it works with products like Windows 8 or Server 2012.

Network Access Protection (NAP)
Network Access Protection
Network Access Protection (NAP) is a feature in Windows Server 2008 that controls access to network resources based on a client computer’s identity and compliance with corporate governance policy. NAP allows network administrators to define granular levels of network access based on who a client is, the groups to which the client belongs, and the degree to which that client is compliant with corporate governance policy. If a client is not compliant, NAP provides a mechanism to automatically bring the client back into compliance and then dynamically increase its level of network access.
In short is your OS AV up to date if not I am going to use WSUS and and the AV server to patch your system before I allow you to access the network.
