DNS,Domain mirrored and site redirection

Hi,
I have recently add another domain to my dreamhost account. But in the process
mess up my formal domain DNS setting, by making it to mirrored the newly added
domain.
And the more I tried to resolved the issue, I think the more complicated it more.
Now I can not access the wordpress account for the formal domain and no
matter what I did, like reinstall wordpress, active DNS only…the domain still
mirroring the new domain I added
