Are there any drawbacks I should expect?
What about FRS (domain replication)?

Thanks in advance

Unless you changed the tompbstone lifetime of your forest you have gone over that, you can check the value using procedures in the link below

http://windowsitpro.com/windows/q-how-can-i-check-tombstone-lifetime-my-active-directory-forest

If you bring it back up that box will not replicate.   You also won't be able to cleanly demote it.

You clean up the box from AD (metadata cleanup)  http://technet.microsoft.com/en-us/library/cc816907(v=ws.10).aspx#bkmk_graphical

You can either forecfully demote the box (dcpromo /forceremoval) and then add it back to the domain or install windows and promote it again.

Thanks

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

that is different, if it is the only DC  in the forest then you don't have to worry about replication etc.  

Thanks

Yeah there are no tombstones or replication in a single DC forest.   Is this a test lab?  Just wondering how users have been able to logon for 8 months.

Thanks

It was a `frozen` project which now needs to be re-initiated.
So - I'm starting it - many thanks !
