This week's newsletter is all about flashing. No, not that kind of flashing. We're talking about flashing the BIOS of those servers in your back room or datacenter as the case may be. But since you mentioned it:

That's not what you expected, was it? Heh.
From the Mailbag
Let's start by catching up on our mailbag...
Office 365 licensing
In the previous issue Getting Started with Office 365 (Issue #923) we had Kelsey Epps contribute a guest editorial on the topic "Getting Started with Office 365." Kelsey is a Technical Consultant with Concepps Group and he just received a Microsoft Most Valuable Professional (MVP) award--congratulations! You can read the news on his blog:
http://www.wservernews.com/go/1365154307804
NEWSFLASH!!!
Forgot to mention that I was just re-awarded MVP status myself by Microsoft a few days ago, that makes nine years in a row for me as a Microsoft MVP.
(cue the applause)
Anyways, software licensing often changes rapidly nowadays to address evolving markets, and it turns out that there are two new Office 365 licensing options that Kelsey didn't mention in his editorial last issue, so here to clarify things is Ron Grattopp from the US SMB&D TS2 Team at Microsoft:
In the recent guest editorial "Getting Started with Office 365" by Kelsey Epps, in the "What you need to know" section he states: "Microsoft breaks down Office 365 into two plans; P Plans and E Plans." While this is true, there have been some recent changes and additions to the Office 365 subscription offerings that you should be made aware of.
First, to clarify, there are (and have been actually) multiple "E" family plans (E1-4), but even that has changed and now the former E1 and E2 plans are merged with all the E2 capabilities available at the E1 price, but the biggest thing to know about new E1 combo is that this plan does not include the full Office client (Office 365 ProPlus), it only includes the back-end services (Exchange 2013/SharePoint 2103/Lync 2103) and Office Web Apps, which are enhanced in the new Office 365 update but still not the equivalent of the full Office client apps. So the Office 365 E1 price of $8/mo gets you all the Office 2013 back-end services but without the full Office "front-end" client:
http://www.wservernews.com/go/1365154325148
Plans E3-E4 do include the full Office client (Office 365 ProPlus, which is essentially the same bits as the OPP 2013 just sold as a subscription vs a perpetual license), and Office 365 E3 price is $20/mo:
http://www.wservernews.com/go/1365154329570
Office 365 E4 adds some advanced telephony options for an additional $2/mo:
http://www.wservernews.com/go/1365154334101
Moreover, note that plans E3 and above include advanced Exchange, SharePoint, and Lync functionality over the E1 plan. So much for the review of the E family of plans.
Office 365 now has 2 brand new plans: Office 365 Small Business Premium (P2):
http://www.wservernews.com/go/1365154338632
and Office 365 Midsize Business (M):
http://www.wservernews.com/go/1365154343226
One of the most significant things about these new plans is that they make Office 365 subscriptions available through standard licensing mechanisms, specifically retail packaging (which Microsoft calls FPP, or Full Packaged Product, but is now actually PKC or Product Key Card, vs the traditional box) for P2 AND through OPEN Licensing (OL is a form of Volume Licensing) for M. This is really significant for the Microsoft VAR partners out there because 1) you don't need to be a Partner of Record on the subscription to get paid, and 2) you now "re-sell" this as you would any other retail or OL product and thus you get your margin and revenue as part of the customers' upfront payment.
So let's make sure you understand this, yes, you can now bill the customer and the customer now pays you, not Microsoft -- of course, you don't get the recurring PoR fees that you would get under the "Advisor" model (the way you used to have to sell Office 365). Note too that although SBP and M SKUs can be sold as retail or OL transactions, you could also sell these under the Advisor model as well and take advantage of the continuing PoR fees, the option is yours, whatever works better for you -- but at least now you have some billing options.
Both P2 and M leverage the commercial Office 365 back-end services, essentially the same as E1 (meaning without the advanced Exchange/SharePoint/Lync functionality you get in E3-4). There are other differences as well such as size limitations (25 max for P2 and 300 max for M), admin console, phone support (very limited for P2, business hours for M vs 24/7 for E plans), and others, but you'll need to do your own due diligence around that.
The basic value proposition for M however is that you get essentially the same back-end capabilities as E1 (with some limitations as was just discussed) and the full Office 365 ProPlus client (which the E1 doesn't have) for $180/year, which is 25% less than what you pay for E1+OPP as stand-alone subscriptions, and M does allow for AD integration with your on-premise AD like the E plans do.
The P2 has more limited support, console, and no AD integration and has a limit of 25 users max, but otherwise it brings the commercial back-end services of Exchange/SharePoint/Lync and the full Office ProPlus client to the table for only $150/year.
Btw, you can only get M as a pre-paid full-year subscription for $180 (you may hear reference to it as $15/mo but that's for comparison to the other monthly subscriptions only), you can't pay for it monthly. P2 on the other hand does allow for monthly payments, however, when paying monthly, the price increases to $15/mo -- that's reflected right on the home page (linked above).
OK, so as the old announcer Paul Harvey used to say you now have "the rest of the story" -- hopefully this was useful in helping you to know about and understand not only what's brand new in Office 365 but also have some idea of how Office 365 is evolving to meet not only your customers' needs but that Microsoft is responding to the needs and asks of its partner community as well.

Turning off System Restore
In issue 967 Tips for Healthier Servers (Issue #920) we included the following tip:
System Restore in enterprise environments - You should always turn off System Restore on Windows client computers in the enterprise. The reason is that if a user restores his machine far back enough, the machine password for the computer will be wrong and as a result the computer will no longer be functional on the domain.
We received the following feedback from a reader named Dave concerning this tip:
Doesn't that also kill the file version support (shadow copies)? I haven't run into a case of a user using System Restore to restore back. Maybe I'm just lucky (and we have
I asked my contacts on the Windows team at Microsoft if there was any to configure Windows 7 so that users could use Shadow Copies to roll back file changes when needed but not be able to use System Restore to roll back their computers. The response I received was to not disable System Restore using Group Policy but to instead use Group Policy to push out the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\RPSessionInterval=0
However, since this change is outside the normal test matrix it would be best if you test it thoroughly before implementing it in your production environment.
Fixed or Dynamic VHD for SAN
Another tip that we included in Issue #920 was this one:
Fixed or Dynamic VHD for SAN? - Opinions vary but the general consensus is that fixed virtual hard disks (VHDs) are more "SAN-friendly" than dynamic VHDs when it comes to storing virtual machine files on a storage area network.
Here's what a reader named Quentin replied to us in response:
Variable size VHDs can either be a handy thing that produces great results, or can be a great way to hide problems and make them very difficult to find and troubleshoot.
Good things to use variable size VHDs for - anything that stays relatively static in content, but might occasionally need to expand. O/S disks are something that fits this category. You rarely change anything on an O/S disk - that is unless you have a dynamically sized page file. If you are going to do a variable sized VHD for your O/S, then fix the page file size so it isn't changing up and down all the time.
Bad things to use variable size VHDs for - anything that constantly grows in size. Every time a variable size VHD bumps up against its max size on disk and needs to add some more blocks, there is a significant overhead, at least in the O/S managed versions like HyperV for instance. So the worst case scenario is an SQL DB that grows the DB or transaction log. Performance can be downright dismal to the point where SQL itself will throw errors into the log about the disk speed. The problem isn't disk speed per-see, but the overhead involved in resizing the disk with almost every transaction. MS has actually done a lot of re-writing of the algorithm on this for 2012 server, so the impact is far less, but you are still better off with fixed size disks for DBs. If you happen to be using SAN attached storage and can present the LUNs as raw (VMware) or passthrough (Hyper-V), then even better. Troubleshooting a disk that is constantly changing sizes is sometimes a bit obscure and monitoring tools may just report a slow disk, but not tell you why it is slow.
If you are working with SAN directly, then things are a bit different. SANs may give you more options as to how to provision and have better algorithms to handle expansion. At least all the overhead is not in your VM or server, but in the storage processors on the SAN. With extensive caching it can ease the resizing penalty, or maybe even remove it entirely since some operations can be done in parallel.

Now on to our main topic for this issue...
To Flash or Not To Flash
How many times have you flashed the BIOS on a motherboard or controller card and ended up turning your precious server into a lovely paperweight?
It's happened to me twice: once when I tried upgrading the firmware on a RAID controller to resolve a performance issue and the other time when the vendor I bought a server from said it that a BIOS update had to be applied to resolve a critical issue of some sort. Both occasions then led to lengthy phone calls with the parties involved.
Should you or shouldn't you?
Reasons for flashing
The arguments for making sure server hardware always has the latest BIOS version are basically these:
- To address issues of performance or reliability for the server or controller. Just as such issues can often be resolved by updating server components with the latest device drivers, the same can often be said with regard to updating the BIOS of your server or the firmware on your RAID controller.
- So you can make use of new features that the manufacturer has enabled for your system or device by means of a firmware update.
- When the manufacturer says you absolutely must upgrade the firmware of their device for reasons they might or might not explain in detail. For example, the vendor might release a fix for a critical bug, and just because you've been lucky so far and haven't hit that bug doesn't mean you won't someday.
Reasons against flashing
Some scenarios where flashing the BIOS of server hardware could be a bad idea include:
- When your hardware is out of warranty. If you flash the BIOS of an out-of-warranty server and end up bricking it, the vendor might wash their hands and say it's not their problem.
- When the server is the only one you have that can run some business-critical application. If you can migrate the workload to another server, that's fine, but if not then you might not want to take a chance blowing up your business.
- When you only have one of that particular type of device and it's being used by a server running business-critical applications. That's why you should always buy at least two of each type of RAID controller card you use in your environment as then you can use one as a guinea pig for things like flashing the firmware on it.
- When there's a chance that something could go wrong during the flashing process. For example, if you've been experiencing intermittent power outages and you're not using a UPS (eek!) then you don't want to risk flashing your BIOS in case the process gets interrupted before it finishes.
How not to flash
The actual steps for how to flash a BIOS will depend on the hardware of the system or controller. But there are certain things you generally shouldn't do when it comes to flashing firmware:
- Don't skip intermediate firmware versions. In other words, if the vendor releases versions 1.2.5 then 1.3.6 and then 1.4.9 but your hardware is still at version 1.0.0, then don't simply apply the update for 1.4.9. Instead you should apply each successive update in order, otherwise you might risk bricking your system.
- If you're going to update the firmware of one component of a system, make sure you do the same with the other components of your system. For example, I've heard of a situation where someone upgraded the firmware for the vendor's remote management controller and then couldn't connect to it remotely over the network. Then once they updated the device driver for the server's network card, they could remotely manage the server. So if you're going to keep one aspect of your server hardware (BIOS, firmware, drivers) up to date, you should keep it all up to date.

Tip of the Week
Here's a tip on performing forest upgrades in Active Directory environments.
After upgrading your schema, you might want to raise your forest and domain functional levels. As a best practice, follow these practices:
- Before changing your forest functional level, take at least one domain controller offline from each domain in your forest.
- Before changing the domain functional level of any domain, take at least one domain controller offline from the domain.
- In both cases, you should make sure that the domain controllers you take offline do not hold any flexible single master operations (FSMO) roles in the forest or domains.
- Keep the domain controllers offline for 48 to 72 hours after changing functional levels; if no issues are found, you can return the offline domain controllers to service. If issues are discovered, however, you can use your offline domain controllers as the source for rebuilding servers if a rollback to a previous functional level is required.
The above tip was excerpted from my book Training Guide: Installing and Configuring Windows Server 2012 from Microsoft Press:
