Recently I was trying to backup a workstation using Veeam Agents using Local Credentials

When the job ran to install the Veeam Agent an error came up 

The network name cannot be found. (ERROR_BAD_NET_NAME).

Trying to ping the IP and DNS worked fine

I was trying to Authenticate using .\Administrator ( Which should use its local Administrator account as on the domain

I had to change to PCNAME\Administrator to get it work
