FAILED: An error occurred during the conversion: 'The operation experienced a network error'

Hi everyone.

I was used VMware Converter Standalone 6.0 to converter server 2003 on Hyper-V to host ESX of vCenter.

Hyper-V have IP : 10.132.2.200

vCenter have IP: 10.132.2.177

Host ESXi have IP : 10.132.2.192

We haven't policy firewall for 3 IP this. All ports are open in Firewall.

But, when I convertering 1% that have error with status : FAILED: An error occurred during the conversion: 'The operation experienced a network error'

So, Can you help me fix case this ?

Best regards.
