We are trying to perform SDR in our Test environment which is under different domain and our Backup Exec server is in Production domain. After booting the SDR iso in Test environment I am getting an error "Unable to establish communication with Backup Exec server The network path was not found."
We have enabled TCP port 10000 on the Firewall and able to ping Backup server from Test infra through IP address but through hostname ping is not happening.
Kindly suggest what needs to done to establish the communication with Backup Exec server.
Did you try doing using IP address in "Backup Exec Server" name field during SDR restore, instead of hostname ?
You may need to allow more than just port 10000. Take a look at these ports allow traffic V-370-59792-00041 - How to configure Backup Exec with Firewalls (veritas.com)
Also, if you are using just the host name, then try using host.domain. Plus verify that you are pointing to the correct DNS server for your IP settings.
