Howto add RIS drivers??????

 i have an environment which is on Veritas Netbackup Server 6.5 on Win2003 Server

i am facing an error while restoring BMR backup on different hardware

Failed to install Network adapter -- Check WINBOM

even though i have already added the NIC driver via packages. after research i come to know that the RIS driver for the NIC(the client on whom i try to install BMR backup) is not in the Veritas Netbackup 6.5...How can i add RIS driver for any particular NIC
