Connection Failed trying to find Network Drive

[naveed2006]

Hello
My company uses a network drive attached to our router. I can connect to the drive fine, but only after a fresh reboot. If I turn on off the MBP or hibernate it, when it boots back up it tells me it can't find the network drive.
Trying to reconnect to the network or turning airport on and off doesn't work.
I have a mac mini that i never shut off that never loses connection, only the laptops.
Any ideas
Joe

I'm having the same issue with my 13" unibody MBP running SL. Can connect to an SMB network drive after a reboot, but if I go to sleep then I can't reconnect.
