My dc aren not replicating (this is the error which appear after run netdiag /fix)

[warning] The DNS host name 'jfsmainserver.jfs_domain.jfs' valid only on Windows 2000 DNS Servers. [DNS_ERROR_NON_RFC_NAME]
PASS - ALL the DNS entries for DC are registered on DNS server '' and other DCs also have some of the names registered

is because i have a _ in my active directory name e.g. jfs_Domain.jfs ?
if so is that my the dns won't replicate?

Yes it's because of the underscore.
