Hi, In time honoured fashion I am replying to my own post, as I think I have figured out a workaround to my issue. Hopefully this will help others - here's what I did.

First step was ADSI Edit, to create it - but then I discovered that whilst ADSI Edit can create many things, a RID Set is not one of them. Second step was LDIFDE, I exported the RID Set from my other DC (in the other site), edited the LDIF to make a new RID Set for my existing DC - but couldn't import it ("The server is unwilling to process the request") Finally I hit upon the plan of transferring the RIDAllocationMaster FSMO role across between the DCs: second-existing-dc# samba-tool fsmo seize --role=rid Attempting transfer... FSMO transfer of 'rid' role successful ERROR: Failed to initiate role seize of 'rid' role: objectclass: modify message must have elements/attributes! The transfer was successful, but some kind of error occurred.. (!) But, I was able to transfer the role back to the first DC - and this time, a RID Set finally appeared in AD! I did, however, get exactly the same error. This happened however many times I transfer the role, and for any role (I tried all of them :-)) existing-dc# samba-tool fsmo seize --role=rid Attempting transfer... FSMO transfer of 'rid' role successful ERROR: Failed to initiate role seize of 'rid' role: objectclass: modify message must have elements/attributes! Still.. I have now been able to successfully join my domain - which does solve my initial problem, so I'm happy there at least. (Interestingly, my shiny new DC does not have a RID Set.. I'm not yet sure if this is good, or bad! :)) Hopefully this post will be helpful to somebody in the future... Just a note, however - I hardly ever check this gmail account, so please don't rely on a speedy response if you do see this post and want to reply to me personally!
