DOS network logon

We have a DOS pc running a process program. It connects to the network to copy files up to a server. The problem is, if the PC gets rebooted, the user needs to enter a username and password. If they mistype, DOS doesn’t give a warning to try again and the bootup continues and no connection is made. MY question is there a way to have DOS do an auto-logon? Some sort of batch file or lines to add to the autoexec file.??
Thanks Dave,,
