Net Start / Net Use Command

I have a voice mail computer that uses DOS as it's operating system
I wanted to find out if it's possible to have the system automaticall
login to the domain with a specific user and password using th
net start or net use command in the autoexec.bat file

My autoexec file appears as such now

C:\NET\NET INI
C:\NET\NETBIND.CO
C:\NET\UMB.CO
C:\NET\TCPTSR.EX
C:\NET\TINYRFC.EX
C:\NET\NMTSR.EX
C:\NET\EMSBFR.EX
C:\NET\NET STAR
C:\NET\NET USE lpt1: \\PrintServe\PS_HP4 *password hidden* /Persistent:Yes /savepw:Ye
C:\NET\NET USE Z: \\Server\Profiles /Persistent:Yes /Ye

The problem is, that I can't seem to make it login automatically by usin
the batch file. No matter what, it is requiring me to enter the password
Any help with automatic login would be greatly appreciated

Cheers
