Enterprise Vault Unable to query the status of a vault service

Hi Guys,

I'm trying to migrate enterprise vault 9.0 to a 64-bit windows 2008 server.  I already did the steps before running the EV configuration wizard. But when I ran the EV confgiration wizard I got the following error message:

Unable to query the status of a vault service Service:

Service: Enterprise Vault Directory Service

Computer:evexchange

Error: The RPC is not available

I already point the DNS alias to the new name of the EV Server and flush the dns but it doesn't work.

Please help.

Thanks.
