Situation

When attempting to discover or add a workload that is behind a NAT firewall the following error appears:

Object exporter specified was not found (HRESULT: 0x80070776)

Resolution

Add the following entry into the C:\WINDOWS\system32\drivers\etc\hosts file on the Migrate server, Protect server or Forge Management VM:

x.x.x.x hostname

Where x.x.x.x will be the public IP of the workload and hostname will be the hostname of the workload.

Additional Information

This error occurs due to a known limitation in DCOM when connections are made through a NAT firewall.  The discovery process connects to WMI on the workload being discovered, which runs on DCOM. 

 
In order to test this connection without attempting a discovery follow the steps below:

1. On the Migrate server, Protect server or Forge Management VM go to Start -> Run and run the following:

wbemtest

2. Ensure the namespace is:

 \\%IP_address_of_machine_being_discovered%\root\cimv2  

3. Enter the username and password as would be used to discover the machine

4. Click Connect
