Thanks for the reply - but that's a different issue. The article you point to is for an issue with hosts running on OS less than Server 2012 R2 - but as stated, that is exactly what I am running.
Also, the example shown shows the license status as: 'OBB_GRACE'. Mine does show correctly as 'Licensed' - it's just the rearm count showing as '-1' that is a little odd and worries me.
Here's the relevant sections from the result when I do a script slmgr.vbs /dlv all
I've taken out all the IDs, but they are there OK.
