backup across network

SQL Server newbie question ~ how can I backup a database to a directory in mounted network drive. when I attempt, the server tells me the drive/device is inaccessible. but from the command line, no problem accessing the directory. i have done research on the web and MSN site -- and the info states that it may have to do with permissions. if I can see the drive from command line -- can SQL Server "NOT" see it also? please let me know where I'm falling off the brain wagon...tiaMaybe I'm missing the point, but I've been told not to specify logical drive letters (like D:), rather to use server names, for instance \\server\ etc.|||Before a couple of days I have to solve the same problem by massive google search on the web :)
The problem is that the account on which the SQL server runs hasn't got privileges to see the network. By default, when installed SQL server is executing under system account 'LocalSystem' which hasn't got rights to view the network. Even if you try to backup the database from Enterprise Manager and select a file the dialog just shows local hard drives without network.
So to make backup accross network the user that SQL Server runs onto has to be changed to someone who has the rights for seeing network - fixed user 'Administrator' or any account that access the computer with administrator rights. In Enterprise Manager right-click on SQL server and select properties from the context menu. In the Properties window go to Security tab page, and select radio button 'This account' at the bottom of the window. Next to the radio button appear textboxes for user name and password where name and password of user who can see the network is entered.
Also when specifying the path in 'backup database' command use the notation '//server_name/shared_directory/file_name'. Directory where the backup will be made have to be shared on the network and the computer where SQL server runs have to be able to access it (sharing to 'Everyone' group will do this).|||'//server_name/shared_directory/file_name'

You might be better off using \\servername\directory\filename. Just an fyi.
