How to control how long an object is recoverable in the AD Recycle Bin.

The active Directory Recycle Bin is your tool to recover a deleted object, and all it’s associated properties. An object is only recoverable for a certain length of time. You can configure this period of time to meet your organizations needs. First you need to turn on the AD Recycle Bin. The command below will do this:

Enable-ADOptionalFeature –Identity ‘CN=Recycle Bin Feature,CN=Optional Features,CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=Your forest root domain’ –Scope ForestOrConfigurationSet –Target ‘Your forest root domain’

Once you have turned it on, any object delete after this point can be recovered. By default, the retention period is 180 days. To control the amount of time that you have to execute the recovery:

Set-ADObject -Identity "CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=" -Partition "CN=Configuration,DC=" -Replace:@{"msDS-DeletedObjectLifetime" = }

On a final note, remember that this is a Windows Server 2008 R2 feature.

Error icon when creating a GPO Preference drive map

You may not have an error at all. Take a look at the drive mapping below. The red triangle is what threw us off. It is not an error. It is simply a color representation of the Replace option of the Action field in the properties of the drive mappings. Create action This give you a green triangle. The Create action creates a new mapped drive for users. Replace Action The Replace action gives you a red triangle. This action will delete and recreate mapped drives for users.
