I am having an issues with my Exchange 2010 servers. I have two servers that have HUB/CAS/MAILBOX installed on them. They are
configured to use DAG failover cluster.
I experienced an issue recently where the DNS entry for the DAG and the MAIL01 server where missing from DNS on the Domain
Controllers. I read online that a way to fix the issue was to recreate the DAG DNS and make sure it has special permissions so
that the two mail servers can update the DNS entry.I tried that but it didn't work. I also recreated the DNS entry for the MAIL01 server.
On the Active Node of the Cluster I get the following events:

your DNS server administrator to verify the cluster identity can update the DNS record 'DAG.domain.local'.
I need some help with this issue and any suggestions would be great.
