DFS Namespace stops working after Transferring PDC Emulator role

Im getting this error when opening DFS. I would appreciate any help I can get. \\mydomain.com\public. The namespace cannot be queried. The specified domain either does not exist or could not be contacted.

I looked in DNS and there is an SRV record for it. Amy I looking in the wrong place?

Here is a clue... from the secondary dc, I cannot ping the PDC by the FQDN. It will ping without the domain extension.
