Domain Functional Levels - Windows Server 2008 R2

Greetings.  Our domain is at functional level Windows Server 2008.  We have three (3) DCs, all running Windows Server 2008 R2.  I'd like to raise the functional level to Windows Server 2008 R2 to enable the AD Recycle Bin.

1. I haven't read any negative consequences of moving the functional level from 2008 to 2008 R2.  Are there any possible problems ?

2. We only have one domain.  Our forest functional level is also 2008.  Do I raise that in conjunction with the domain functional level ? If so, which order do I proceed ?

Thanks much.

As long as you make sure that your AD Replication is working properly and is clean of errors there should be no issues. Use the below commands...
- repadmin /replsum
- repadmin /showrepl
- repadmin /bridgeheads
- Dcdiag /v

We only have one domain.  Our forest functional level is also 2008.  Do I raise that in conjunction with the domain functional level ? If so, which order do I proceed ?
Always raise the domain functional level first. Then raise the forest functional level. If you raise the forest functional level first it will automatically raise the functional level for all Domains beneath it.

Also you need to be aware that raising the functional level to 2008 R2 does not automatically enable the recycle bin feature this is a manual step as well.

Just another side note, you do not have to enable the Recycle Bin feature to restore deleted objects. You can also use Ldp.exe to restore deleted objects.

Excellent. Thank you, Will.  I use the AD Replication Status Tool every day.  Looks pretty clean :-)  I'll check out ldp first.
