I do. My main machine at home is a domain controller running Active 
Directory. I needed this for some Kerberos work that I was doing. I also 
run BIND 9.5.0 on it rather than Microsoft's DNS.

I have search for information in it but I don't see anything specific 
and it didn't seem to add any records to the DNS when I ran w32time on it.
