Netdiag /fix equivalent in 2008R2? (Force DC to re-register all DNS entries)

Some of my DNS are run on BIND, and when I promoted a DC, it may not
have been able to register its DNS records due to this. I think I've
alleviated the problem and done a "dcdiag /test:registerindns /
dnsdomain /v", and it tells me the server is able to register
entries. It still hasn't though, and it's causing replication and app
problems. Normally I'd do a "netdiag /fix" to force it to re-register
DNS entries, but since that was ripped out of 2008, I'm at a loss.
What would be the equivalent in 2008R2, or how would I force the DC to
register itself? Thanks.
