Problem doing a sql cross restore.

Well, I am stuck in this situation where the sql pleople want to copy the productive DBs into the Testing sql server.

I tried doing a sql restore through the client, downloading the batch file, editing it to send the db to an alternate location, but I can´t get it to work.

I get error 5.

As my knowledge on sql restores is very limited, I read a bunch of articles, but could not get past this problem.

What is it that I need to configure in order to get sql cross restores working?

What user permitions should I have in case that might be the problem?

System is running:

Windows 2008 r2 master server

windows 2003 media server

Netbackup 7.5.0.4

Thanks in advance.
