<b>net use</b> lets you specify a password. I believe the format would be something like
<pre>net use X: \\shared\drive /user:domain\user drivepassword</pre>
You can get more info with “net use /h”
Or setup a Windows Domain (if you don’t already have one) and grant the users accounts rights to the network share so that they use their domain account to access the share instead of the Administrator account.
