DPM 2010 (Domain A), Sharepoint 2010 (Domain A), SQL Server 2008 R2 (Domain B): Protection Group Problem SQL named is in wrong domain format.

Question

Good Evening,
So I have 3 Servers in all, with the following configurations:
Server1: DPM2010.contoso.com (Domain A)
Server2: Sharepoint2010WFE.contoso.com (Domain A)
Server3: Sharepoint2010DB.contoso.net (Domain B)
I have prepared sharepoint2010wfe.contoso.com appropriatly by installing the DPM Agent, running configuresharepoint.exe -enablesharepointprotection & ConfigureSharepoint.exe enableSPSearchProtection.
I have prepared Sharepoint2010db.contoso.net by installing the DPM agent to the server using the manual installation method and creating local user credentials and connecting to the agent through install > attach agent.
In DPM all of agents are healthy so I go over to create the protection profile and I recieve the following error: DPM cannot protect your windows sharepoint services farm until you install agents on the following server: Sharepoint2010db.contoso.com (ID:
956)
I have already attempted creating an alias on the WFE server for Sharepoint2010db.contoso.com and have it point to Sharepoint2010DB.contoso.net but this did not resolve my issue at all.
Also please keep in mind that pinging Sharepoint2010db.contoso.com is invalid as there is not a valid DNS entry of any kind, Im not even sure where this name is coming from other than some sort of a mashup. Also I am unable to domain join the SQL server
to contoso.com because of licensing costs.
A resolution to this issue woudl be greatly appreciated.

Hi Deepan,
I run into exactly the same problem with SharePoint 2013 and DPM 2012SP1. SharePoint servers run in domain a, sql 2012 in domain b. We use a SQL alias SharePoint_PROD that is configured with the fqdn of the sql server (sql20.b.com), but DPM resolves it to
sql20.a.com when I try to configure SharePoint protection.  Is there any solution yet?
