How do I back up my Windows 2008 Server to a network share?

Hello all,

I'm trying do a full backup over the network to a shared folder on another server. I understand the limitations of the Windows Server Backup, and am trying to use a workaround found here: http://blogs.bitwizards.com/Bryan_Soltis/post/2008/09/23/Windows-Server-2008-Backup-to-a-network-share.aspx

So, I'm trying to create a batch file that will run the backup every night. This is the command I'm trying to use:
Wbadmin start backup -backupTarget:\\server\shared-folder -include:C: -vssFull -quiet

But I get this error (HELP!):
-----------------------------------------------------------------------------------------------
C:\Users\administrator.DOMAIN>Wbadmin start backup -backupTarget:\\server\shared-folder -include:C: -vssFull -quiet
