[Samba] removing windows 2003 from samba4

[Alan]

Hello!

I've setup last version of samba on git repositories, Samba version
4.0.0alpha16-GIT-43ab5aa
and joined a windows 2003 as a additional domain controller, but when i try
to remove these domain controller with dcpromo command appears the following
error on log.samba:

[2011/06/07 00:18:55,  0]
../source4/dsdb/repl/drepl_out_helpers.c:765(dreplsrv_update_refs_done)
  UpdateRefs failed with WERR_DS_DRA_BUSY/NT code 0xc00020f6 for
f34e07bd-b0b9-4398-84ca-b3f030a33ef9._msdcs.samba4.casa
CN=Schema,CN=Configuration,DC=samba4,DC=casa

On windows appears that the directory service is very busy to finish
operation now...

regards,
