ensure that there is now network issue between the master and clients

Thanks I will review that article you gave

Two things are needed for successful client backup:

1. Port connectivity
2. Hostname lookup

For port connectivity, you need vnetd (13724) open in both directions between server and client. As from 7.0.1, PBX (1556) will be tried first, then vnetd if PBX fails.

Forward and reverse lookup is needed - client needs to resolve server IP address to hostname that appears in client's SERVER list. Check DNS and/or hosts file on server and client to ensure successful forward and reverse name lookup.

Do the following to troubleshoot:

Create bpcd log folder on client in netbackup\logs folder.

Run the following from cmd on the master/media server:

bptestbpcd -client <client-name> -verbose

Please post output of command as well as client's bpcd log file.

update your host file on master / media  / client

I think you need to update your host file as shown in below....

192.163.3.44     myserver01     myserver01.mydomain.com

Thanks for the info..

I just disable the firewall service and exclude the netbackup installation folder from scanning.

Im not getting any error now
