Symantec Encryption Management server clustering issue

Dear Team,

we are facing issue when joining our encryption management servers in a cluster. Inspite of meeting all the environmental requirements, the cluster page displays that Join could not be complete and the error message says that the remote server has the same id as the local server. Is there any way to change this ID? Also there is a continuous error mesage saying that reverse lookup failed for the clustering IP where as we have both the lookups in place in the DNS server.

We are stuck with this, need help in this issue..

Thanks
