Environment
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.
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
