Hey Badr,
Try this.
- On the physical machine on which the converter is installed, update the /etc/hosts file with the exchange server's host name and IP address, your physical machine's hostname and IP address and the VC/ESX host where you are converting - that machine's hostname and IP address
- Do the same for the exchange server
- Do the same for the VC macine/target ESX machine
- Make sure from all three machines both forward and reverse name resolution is happening - .i.e you are able to ping both by hostname and IP address to all three machines from each other
- Ensure from all three machines, you are able to connect to port 443 using both IP and hostname/FQDN
Then try the conversion
Thanks
a
