When you do a P2V or V2V of Windows 2008 server using VMware Converter you might get the below error:
Unable to contact the specified host. The host is not available, there is a network configuration problem, or the management services on the host are not responding.
In order to execute the conversion process, it is necessary to open the required ports on the source. This error would be displayed when the required TCP and UDP ports are not open.
Hence, the best solution is to disable the firewall to fix the issue.
In my case the issue was fixed using the below command.
NetSh Advfirewall set allprofiles state off
