HP Proliant server - Multiple Logical Drive Creation with single R5 array

I got a new HP ProLiant DL160 G6 server to replace my aging ML150 G2 file server. It is equipped with the Smart Array P212 controller and 4x 1 TB SAS drives. The OS is Windows Server 2008 R2.

I had to create 2 logical drives (LUNs) from the usable 3 TB RAID 5 array because the disk where Windows is installed must be a MBR disk, which is limited to 2 TB. By having 2 LUNs (100 GB for the OS and the rest for storage) Windows sees them as separate disks, so you can configure the bigger volume as a GPT disk, bypassing the 2 TB limit.

When you press F8 at boot time to access the P212 setup program, you do not have the option to create logical drives inside your RAID array. To enable this function, you must boot on the provided "Easy Set-Up" CD, and access the ACU there.

After that you install the OS on the smaller volume. When Windows is installed, you can convert the second logical drive as a GPT disk, with full access to the disk space.

Thanks to gregersenj from HP ITRC forums for pointing me in the right direction !

GPO to disable password protection of Microsoft Office files

We do not want our employees to password-protect Microsoft Office files in case they forget the password or they leave the company. If you use AD, there is a GPO to disable this feature in Office.

First you must download the "Administrative templates" for the version of Office you use. Here are some links:

Extract the files to a temporary folder.

Launch "Active Directory Users and Computers" (aka ADUC) and right-click the domain or OU you want to add the policy to. Select Properties and go to the "Group Policy" tab. You can then edit an existing policy or create a new one.

Once inside your GPO, right-click "Administrative templates" and select "Add/Remove Templates...". Click Add and browse to the temporary folder where you extracted your templates. The name of the template you need to load varies with the version of Office. For Office 2007 the file you need is "office12.adm". Click Close.

Back in your GPO, you will see settings that were not listed before. Browse to "Microsoft Office System 2007", Security Settings and the policy you need to enable is the third last.

At the next policy refresh (you can force a refresh on a client computer by typing "gpupdate" at a command prompt), the "read-only password" option in the "Save as..." dialog box of Word and Excel will be grayed out !

BTW if someone sets an edit password on a document, don't worry. Open the file as read-only and copy and paste the content in a new document.
