AnswerCant Raise Domain or Forest Function Level from 2008 to 2008 R2

    Hi all

    I have had 4 Windows 2008 Server Core Dc's running (2 sites, 2 dc's in each site) for a while now.

    We have slowly decommed each one one at a time (moving FSMO roles accordingly etc etc) and replaced with new Windows 2008 R2 Standard Edition Server Core.

    We finally replaced the last DC yesterday and removed one completely (from one site) temporarily. So now we have 2 x 2008 R2 DC's in 1 sites, and 1 x 2008 R2 DC in the other site. Everything is fine AD wise, FSMO roles all placed correctly, AD working just as it should, HOWEVER I cant seem to even get the option to raise either the Forest or Domain functional level from 2008 to 2008 R2 (we want the AD recycle bin!).

    We have prepped the schema a while ago with

    adprep /domainprep
    adprep /domainprep /gpprep
    adprep /forestprep

    and if I try and run these again it says "Its already been done, so no need" or something like that.

    But if I go into ADUC or ADDT and connect to any of the DC's it just says "Forest level = Windows 2008" or "Domain Level = Windows 2008" and "This is the highest level you can have at the moment" etc etc

    Any ideas?

    Cheers!

    Andy

    Hi Andy

    I suspect your ADUC and ADDT tools may be Windows Server 2008? 

    Try with the R2 RSAT toolset or with Powershell 2.0, e.g.

    get-adforest | ft forestmode
    
    set-adforestmode -identity mydomain.com -forestmode windows2008r2forest

    Oh, and we've activated all the DC's (2008 R2 Std Server Core) with "start /w slmgr.vbs -ato" successfully.

    Under "Domain Controllers" in AD all 3 DC's show up as "Windows Server 2008 R2 Standard"

    All 3 DC's are GC's. All running the integrated AD DNS Zone for our domain

    The AD Schema version in AdsiEdit.msc shows as Version 47 which is Windows 2008 R2 (44 was the previous for Windows 2008)

    Cheers!

    Any chance some of your decommissioning left orphaned DC objects in AD? You might want to try running ntdsutil (metadata cleanup context) to list all sites/DCs to determine whether this is the case...
    Just to confirm, your current functional level is Windows Server 2008 - correct?

    Jorge, There is no error as I explained. Its just not giving me the option to raise to R2. Repadmin is irrelevant.

    Marcin, we did do some checks a while back and the metadata is completely clear from old DC's. appreciate your comments anyway.

    Tony, you are right my friend. We were just using the 2008 tools. Used RSAT on a Win7 and a 2008 R2 Full install server (as our DC's are cores), and hey presto, the option is there. Its obvious when you think about it, but I dont remember the MS docs ever explicitly saying to us it. Doh!

    Cheers

    Did you used the 'adprep' tools from the windows Server 2008 R2 CD ?
    It's in the support dir.

    Run this version again on the Schema Master.

    adprep /domainprep
    adprep /domainprep /gpprep
    adprep /forestprep

    Button [Save As] Should give you the info why it won't...

    I appreciate your response but as noted above I had done all that and the schema was updated to the correct version.

    Irrelevant, as I have fixed the issues by using the ADAC in R2 as apposed to DSA in Windows 2008 (non r2). The issue is the gui of the old DSA and you must use the R2 RSAT tools instead. (Tony's answer above)
