Veeam 6.5 replication job fails with “Soap fault. No DataDetail: 'get host by name failed in tcp_connect()', endpoint: 'https://DR-vCenterName:443/sdk'”

I recently ran into an issue where my Veeam replication job that replicates VMs from a head office to a DR site would fail with the following error:

[30.06.2013 16:37:40] <  6648> vim| >>  |Cannot get service content.

[30.06.2013 16:37:40] <  6648> vim| >>  |Soap fault. No DataDetail: 'get host by name failed in tcp_connect()', endpoint: 'https://DR-vCenterName:443/sdk'

The infrastructure consists of a Veeam backup and replication server in the head office with a dedicated Veeam proxy target in the DR site along with a vCenter and ESXi host serving as the replication target.  The proxy in the DR environment wasn’t joined to the domain or configured with DNS settings so just as the error apparently suggests, the cause of the failure was because the proxy in the DR could not resolve the vCenter name in the DR.  A simple host record fixed this or if preferred, configuring the DNS settings of the DR proxy with the domain’s DNS servers would achieve the same results.  I opted to use a host record because the DR environment I was working in was a hosted solution that did not allow DNS queries from DR to the head office.
