Creating a persistent network drive mount

I have a D-Link DSM-G600 ethernet-connected hard drive that I use to share all of my iTunes files on my home network. My iMac is hard-wired via the Linksys WRT350N router as is my D-Link hard drive. I can easily connect to the root share of this drive using the Finder window, however every time I have to reboot the iMac, if I forget to go into Finder and reconnect to the drive, my iTunes starts with an error message saying "iTunes cannot locate the iTunes Library folder". Once I manually reconnect the drive, everything works fine. In a Windows OS environment, I can set that mapped drive location to automatically reconnect every time I reboot the PC. Is there a way I can tell the Mac OS X to also reconnect to this external drive automatically at startup?
