Group Policy Setting of the Week 4 – Shared Printer

This week I have selected the “Shared Printer” Group Policy Preference as my Group Policy Setting of the Week (GPSW). This is arguably one of the most wanted group policy settings by Group Policy admin’s that was missing before group policy preferences. It was possible previous to preferences to map printers natively in group policy using the pushprinterconnections.exe option but like the Star Trek Deep Space Nine episode “Trials and Tribble-ations” we defiantly “do not discuss it with outsiders” as this is just a setting we would rather forget.

The “Shared Printer” options can be found under by right clicking on “User Configuration > Preferences > Control Panel Settings > Printers”. As with most group policy preference settings you also have the option to CRUD (see Group Policy Preferences Colorful and Mysteriously Powerful Just Like Windows 7) which means you can also use this option to remove any printer mapping that people have to printer queues that no longer exist.

Now it has always been fairly straight forward to map printers via logon script either via batch, vbscript or even kix scrtip however the real power of this setting is that it can now take advantage of the really powerful targeting options. More commonly you can map a printer via a single security group or IP range but you can really start to do some really advance targeting when you start to combine multiple targeting setting using Boolean logic. If you want to see some more advanced targeting options for printer mappings then check out my “How to use Group Policy Preference to dynamically map printers when using Roaming Profiles” article.

As you can see above you can also use this option to set the default printer for your users which can be very handy if people have a habit of always printing to the really expensive A3 colour printer on your floor when you are trying to reduce cost. Just use the default printer option wisely however as you could end up annoying your manager who likes to printer to their locally attached printer.

Group Policy Setting of the Week 3 – Group Policy Preferences Power Plans

I have selected for this weeks Group Policy Setting of the Week (GPSW) the group policy preferences that is used to configure Power Plans. While configuring power plans for your environment may be nothing new if you have deployed third party tools, you can now avoid the added expense and complexity of doing this as this functionality is now provided out of the box.

This option can be found under User Configuration > Preferences > Control Panel Settings > Power Options and is used to control the individual power plan for your computers. Strangely I have found that this option only works under the User Configuration setting which I presume is the case because it is normally a user configured setting even though the option is under the computer configuration section as well. This power plan option also work with Windows XP however you do need to explicitly select the correct OS power plan as the XP plan will not work on Vista+ and vice versa.

Windows Vista and later Power Plan

Windows XP Power Plan

As you can see this can be used to configured almost all the power plan setting that your version of windows has to offer. One notable omission is the CPU System Cooling Policy setting that was introduced with Windows 7 which is not available to be configured in the Vista (or later) power plan.

Left (Windows 7 System cooling policy) Right (Windows Vista and Later plan without the System cool policy option)

If you are interested in more advanced targeting option with Group Policy Preferences and want to learn how to apply different power plans to computers based on the time of the day check out my previous blog article at!8834054641A09100!1133.entry

If you have not already got Group Policy Preferences deployed in your organisation then this is definitely the excuse you need to get it deployed. Go to any manager today and say you can start reducing the power consumption of you computer fleet using software they are already licensed and almost always the reaction will be to have it done yesterday.


This setting will work on Windows XP or greater if you have the Group Policy Client side extensions installed.
You need to be running the Group Policy Management consol on Windows Vista (Windows 7 recommended) to manage these settings

Group Policy Setting of the Week 2 – Verbose vs normal status messages

This weeks Group Policy Setting of the Week (GPSW) can be found under Computer > Policies > Administrative Templates > System and is called “Verbose vs normal status message”. It is a really simple setting that doesn’t actually do much but I dub this setting the “Make my computer start faster” setting which give users the illusion that their computer are working faster.

So what does it do and how does it make my Computer start faster? This setting displays a number of extra status messages during the start up and shutdown of the computer and when the user is logging on and off.

Some of the verbose status messages you will see are (but not limited to):

Mapping Drives
Playing Logon Sound
Mapping Printers
Applying Power Settings
Stopping Services

You will still see your Applying Computer settings and Preparing Desktop messages however these will be shown for a lot shorter time.

Unfortunately it will not actually make your computer start any quicker but I have generally found that by enabling this option users seem to perceive that their computers are starting up quicker. Why? Well I think its because the extra status messages are holding their attention for a few seconds each time a new one is displayed something like the opposite of watching grass grow or a watched pot that never boils… In any case this is still a handy setting to enable as at the very least will help your IT support troubleshoot logon performance issues.

This setting will work on Windows 2000 and above and it will also show the processing of newer Group Policy Preferences.

Group Policy Setting of the Week 1 – How to remove old user profiles after X days

(This will hopefully be the first of many Group Policy Setting of the Week (or GPSW) articles where I will showcase one policy setting and what it does.)

I just read about this cool new policy setting on the “Ask the Performance Team” blog that will help address the issues of computers hard drives filling up over time with multiple user profiles. Previously you either had the option to purge the local users profile on log off or keep a cached copy of the profile forever. Either users would have to download their profile every time they logon to the computer which could greatly slow down the logon process or their cached profiles was never deleted which resulted in the system drive running out of space. This new setting “Delete user profiles older than a specified number of days on system restart” allows you to set a timer on the local cached profiles so that they will be purged X number of days after being used. This means users who commonly logon to a particular computer will still have their profile cached but users that logon seldomly will have their files cleaned up thus saving precious disk space.

This might sound like a great setting to implement on a Terminal Server however note the clean up wont happen until the server is rebooted. This restriction should not be so bad as Terminal Servers are probably rebooted at least once a month any way for patching (you do patch your terminal servers don’t you?).

This setting can be found under Computer Configuration \ Policies \ Administrative Templates \ System \ User Profiles

NSW Government uses Group Policy AppLocker to build an ‘unhackable’ Netbook

The NSW Department of Education and Training (DET) has come out and said that due to the new features in Windows 7 they were able to essentially build a computer to survive “the most hostile environment you can roll computers into”.

“DET also uses the AppLocker functionality within Windows 7 to dictate which applications can be installed on the device.”

AppLocker is a new feature with Windows 7 that allows IT administrators to lock down application to specific product and/or vendors with having to specific the specific version. This feature allows them to only allow a specific white list of application on the computers. This essentially prevents anyone from running any non-authorised code on the computer thus making it VERY difficult to prevent people hacking the computer with third-party tools or malware. What is really nice with this feature is that it does not stop computer from running applications after they have been updated with hot fixes and service packs as AppLocker works on the digital signature on the file and not a hash of the file itself. This makes the IT Administrators overhead far less as they no longer need to add every possible version of an application to the white list when they want it to work.

While DET does seem to have done a lot in securing the devices to the Nth degree I still reckon it wont take long for someone to find some hack or workaround. I think the itNews headline is just inviting trouble by calling it “Unhackable”. I call it the “If something is said to be “unhackable” then it is far from being secure” maximum. ( More info about Security Maximum’s can be found at ). But don’t get me wrong I don’t think that this will be a flaw in the technology but more a security issue with them forgetting to lock down some or even leaking the default BIOS password.
