Active Directory and Personal Virtual Desktops

leave a comment »

Here’s a nice article from Remote Desktop Services Team Blog, that explain de Active Directory schema requirements for virtual desktop pools and personal virtual desktops.

Microsoft’s VDI solution offers two deployment scenarios: virtual desktop pools and personal virtual desktops. Virtual desktop pools are not dependent on a specific Active Directory schema level; however, personal virtual desktops do need a Windows Server 2008 or Windows Server 2008 R2 schema.

Here are the Active Directory requirements for personal virtual desktops:

  • To deploy personal virtual desktops, your schema for the Active Directory forest must be at least Windows Server 2008. To use the added functionality provided by the Personal Virtual Desktop tab in the User Account Properties dialog box in Active Directory Users and Computers, you must run Active Directory Users and Computers from a computer running Windows Server 2008 R2 or from a computer running Windows 7 that has Remote Server Administration Tools (RSAT) installed.
  • You must use a domain functional level of at least Windows 2000 Server native mode. The functional levels Windows 2000 Server mixed mode and Windows Server 2003 interim mode are not supported.


How to create an Active directory Schema snap-in

leave a comment »

When you try to add active directory schema to your mmc, you notice that the schema option is missing from the “Add or Remove Snap-ins” menu. If you go to the Administrative Tools you also see that no Icon exists to “Active Directory Schema

What’s missing?
Well, since 2000 OS days that Microsoft doesn’t show (by default) the schema option to be used in mmc consoles. There’s a good reason for that. Changing your forest schema affects your entire forest, and that means that you can crash your entire forest with a couple “innocent” changes.

Note: To add Active Directory Schema snap-in to mmc requires only Domain Users group membership. However, making changes to the schema requires membership in the Schema Admins group.

To view the “active directory schema” in the “Add or Remove Snap-ins” menu, you need to do is to register the schmmgmt.dll.

To do that, open a command prompt and type the following command and then press ENTER:
regsvr32 schmmgmt.dll

If the registration was successful, now you should be able to see the active directory schema option available to be added in your custom mmc console.

Step-by step description “create a custom mmc with Active directory Schema snap-in” & “Adding Active directory Schema snap-in to the Administrative Tools”:
1. Open a command prompt, type the following command, and then press ENTER:
regsvr32 schmmgmt.dll
2. Click Start, click Run, type mmc, and then click OK.
3. On the File menu, click Add/Remove Snap-in.
4. Under Available snap-ins, click Active Directory Schema, click Add, and then click OK.
5. To save this console, on the File menu, click Save.
6. In the Save As dialog box, do one of the following:
7. To place the snap-in in the Administrative Tools folder, in File name, type a name for the snap-in, and then click Save. To save the snap-in to a location other than the Administrative Tools folder, in Save in, navigate to a location for the snap-in. In File name, type a name for the snap-in, and then click Save.

Modifying the schema is an advanced operation that is best performed by experienced programmers and system administrators. For detailed information about modifying the schema, see Active Directory Schema.

The process described before is available at TechNet “Install the Active Directory Schema Snap-In“.
