Members of child domain unable to access parent domain servers

We have a Active Directory 2000 forest with a parent and a child domain. Users from the child domain have always been able to access servers and shares in the parent domain until yesterday when they started being asked for username & password, due to their logon account failing to be authenticated.
The issue is DNS related because if they use the DNS servers in the child domain they fail to authenticate but if pointed at the DNS server in the parent domain they can get access. We have used DHCP to point everyone to the parent domain DNS for now but would like to resolve the issue.
DNS appears ok on the 2 child domain DNS servers with DCDiag passing its tests and replication showing as working. Any ideas?
Let me know if any further info needed. Thanks

How about you just delegate the parent zone in the child nameservers.

Current set up is one zone covering parent & child domains. Its supposed to be AD integrated but the list of RRs isn't in sync on both sites. To delegate would I do that logged onto the DNS server in the parent or child domain? Any chance of a rough walkthrough so I don't make things worse?
Thanks
