TAPI3 in Active Directory

Experts:

I have two Win2003 Server DCs in a small (test) domain; I am planning to replace the original DC (with FISMOs).  When I started to run dcpromo to demote the server from DC to standalone, I received a warning indicating that the DC contained the only copy of a TAPI3 application directory; replmon did indeed show a TAPI3 AD partition with no replication configured.  I have no idea how the application partition came to be - I don't use (or test) any TAPI related software.

Note - I am the only domain admin (this is my own test domain) so no one might have put it there.

Questions:
1.  Where might this have come from?  I would not have created this intentionally; could Windows have created this, is it a part of the fax services (which I may have tried installing once).
2.  How can I browse the contents of the partition to see what is actually there (and maybe even why it is there)?
3.  How can I enable replication on the partition so it will survive the DC replacement?
4.  Can I simply ignore the TAPI application partition?  Sure, it will be obliterated, but since it is unlikely that there is anything important in it, that may be the best solution.

Thanks.

an application dir partition is a partition which is installed to facilitate the replication of that application data on to different DC's that would host the partition. i donot know how you got the dir partition for TAPI, but if you want to remove this Dc and still keep the dir partition till you figure out whether to keep the parttiton or not you can install that instance of application dir partition on a different DC, replicate the partition and remove that app dir partition from the first DC.
did you restore this DC from an image ?

you can also view the app dir partition in adsiedit, right click and connect to example dc=forestdnszones,dc=crystal,dc=net.

what is TAPI and what does it do ?
