ال [ومي] مرشح مسابقة - تكون أنت الفارسة في يلمع درع?
ترحيب إلى "البحث للمقدّسة مكتب [ومي] مرشح", هذا بحث شاملة ل ماذا أنت استطاع دعات "الكاملة مكتب [ومي] مرشح". [ومي] مرشح أيّ, ب يستعمل [ومي] [قوري لنغج] ([وقل]), سوفت كنت يمكن أن يلطّخ [دسكتوب كمبوتر] فقط. هو سوفت كنت سؤال عامّة - معنى هو سوفت كنت يمكن أن يستعمل المرشح في كثير نشطة دليل بيئة حول الكرة أرضيّة لمجموعة سياسة ييصفّي.
هكذا, ماذا يكون مكتب حقّا? جيّدا, واقعيّا [إين ثيس كس] سيقول نحن هو الضد من الحاسوب المحمول. [همّ], بعد ذلك ماذا الحاسوب المحمول? يتيح بكفاية: حاسوب مع [ا بتّري]! نحن [هف جت] ال [ومي] مرشح ل يجد الحاسوب المحمول سابقا:
انتقيت * من [وين32بتّري] - لا يحبّ أنت صحيحة البساطة في هذا سؤال?
سيجعل هذا مرشح حاسوب مع [ا بتّري] استجبت إلى الخلف مع "يصحّ" (لأنّ ال [ومي] صنف مثال يكون حاضرة), يعني [غبو] مع هذا مرشح سيطبّق إلى حاسوبات مع بطاريات. حق بسيطة? وأنت أمكن فكّرت هو يتيح أن فقط "التفتت هو حول" إلى اكتشاف مكاتب, مثل:
انتقيت * من [وين32بتّري] حيث توفر! =2
أو
انتقيت * من [وين32بتّري] حيث توفر ليس معدومة
أو
"حيث لا [إكس] يحبّ [ي]" أو ماذا
ربّما هو, ربّما هو ليس… أنا أفكّر هو إلى حدّ ما ملعونة يستعصي! ل [سبوتّينغ] الحاسوب المحمول نحن استطاع يتلقّى اختبرت الأصناف [وين32بورتبلبتّري], [وين32بكمسكنترولّر], [وين32بوتسمودم] أيضا - غير أنّ بطريقة ما يفكّر أنا كثير الناس سيوافقون, أنّ ال "أساسيّة [تينغ]", أيّ يجعل الحاسوب المحمول الحاسوب المحمول, يكون [إين فكت] البطارية وجود!
غير أنّ, إختباراتنا ل [سبوتّينغ] مكاتب فقط (آلات دون [ا بتّري] - نعم, يعرف أنا هذا سيتضمّن نادلات بما أنّ هم "ثابتة" أيضا) يتلقّى ليسوا نجاح بعد! يحتاج نحن على الأرجح فقط ال يصحّ إعراب? وهذا حيث أنت تحصل داخل الصورة!
تكون أنت يمكن أن ينصدع مفتوحة هذا صمولة? هناك سعر باردة!
[مر-ليا] هذا جميعا يبدأ على يرسل قائمة ميلان إلى جانب لمجموعة سياسة شدادات وبنات - يدعى [غبتلك] - يخلق ويبقى ب [غرووب] [بوليسي] غورو و [مفب] [درّن] - الشدادة وراء GPOguy.com و [سدم] برمجيّة. أنت يستطيع تلاقيت القائمة ميلان إلى جانب حق هنا وساهمت في هذا مسابقة إلى ربحت [فر كبي] من ال:
[غبإكسبرت] يتحرّى [بك]
غير أنّ أنت يضطرّ كنت الشخص أولى أن ينصدع هذا شيء, هناك سيكون فقط واحدة رابحة [- ثت] استطاع كنت أنت!
أنا كنت سأقيّم جوابات قادمة - [فيفو]: " أولى داخل أولى خارجا" method is used. Hopefully we'll see the most simple solution first - simplicity works, right? Actually I wouldn't know in this case would I...
One important thing! We will ask you kindly to TEST any WMI query submissions before sending them to everybody on the list. During your testing, you should use a tool to verify the WMI filter against a minimum of 2 desktops and 2 laptops. You can use the free WMI Filter Validation Tool to test you WMI filters in your environment. Personally I’m also using Scriptomatic version 2 and WBEMTEST for finding the available classes, items, queries etc.
Please have a look at the "rules" further down!
Why do this? Well, because it's fun - and useful at the same time... When looking at it generally, the purpose of this filter is to say: "I want these user settings to apply, but only when the user logs on to stationary machines". This can be used for a lot of security related setting, eg. in the case where Automatically cached Offline Files/Folders are unwanted on stationary machines for certain users etc. The job of most WMI filters placed on User policies is to limit which machines the policy setting(s) should apply to (even though WMI filters could check for user specific things too). Besides from that it's a nice challenge, we can pretty easily "spot" laptops, as they have batteries – and desktops don’t, but that’s not good enough for Mr. WQL, is it?!
Stuff we have tried - and the rules
We’ve been around solutions looking for Win32_SystemEnclosure > ChassisType before - which basically doesn’t work in a WMI filter because that’s an Array (and yes, I've also seen lots of posts on forums out there claiming that particular class is the solution – but for WMI/WQL queries it’s not). If would work in a script (because you can add additional logic to scripts), but we are searching for a WMI Filter - not workarounds of any kind!
As mentioned we tried with the Win32_Battery WMI class. However, as desktops don’t know this class at all, they'll return FALSE no matter what. Basically a desktop computer is gonna say “Heck, I don’t know anything about that class *Panic* I’m out!” – or just “False”... Bummer!
We have also tried PowerSupplyState, Win32_DesktopMonitor, Win32_DisplayConfiguration, Win32_SystemSlot, Win32_Fan and other classes – just haven’t found the perfect “this is definitely a desktop WMI item value or class”…
We're basically looking for something like:
A) Select * from Win32_SomeClassOnlyDesktopsHave
Or
B )Select * from Win32_SomeClass.SomeItem = “SomeValueOnlyDesktopsHave”
Or
C) Some way of saying “if you don’t know the class (eg. Win32_Battery), then apply the GPO anyway”
Again, the “quest” is to find the perfect, *universal*, way of spotting “Non-laptops” or Desktops – it can of course be done by looking for some special computer Manufacturer/Model, BIOS version, specific hardware driver or whatever – but that stuff it most likely gonna be different from environment to environment. Also, if we all just used computer names like “DESKxxx” for desktops and “LAPTxxx” for laptops, we could have used WMI filters for computer name – but unfortunately that’s not the case - or at least I won't consider that a valid solution :)
The thing is, that normally it’s the LAPTOPS that have special hardware – like Batteries and built-in Modems, PCMCIA slots etc. – so they are pretty easy to find. With desktop computers it’s another story – hope you can help us out here!
Please, again, we know lot’s of “workarounds”, but what we need is a *WMI filter* and it has to return *TRUE* for *DESKTOPS* (or let’s call the NON-LAPTOPS or NON-PORTABLES, it doesn’t really matter).
Remember, simplicity works - maybe the answer/solution is pretty straight forward? Feel free to post any additional questions to the mailing list!
Another example of what has been tried
We could maybe try to go for presence of PCI (and not Mini-PCI) or AGP slots, as we expect most desktops to have PCI slots (and laptops to have Mini-PCI, but that would depend on the form factor) – or maybe AGP (but does onboard VGA count as AGP? Any PCI VGA cards left out there? Yeah, probably...). If not we could maybe go for something like this:
A) Select * From Win32_SystemSlot Where SlotDesignation = “PCI%”
Or
B) Select * From Win32_SystemSlot Where SlotDesignation = “AGP”
However, this is not accepted as a solution as we cannot say that all desktop computers have AGP slots. But - maybe you can convince us otherwise?
