It sounds like what you want to do is to boot Win2k and "log on" as administrator with a blank password, then utilize SME's resources across the network without validation. Windows will let you get away with this, but SME was purposely not designed with this functionality in mind. I'm hoping that you're aware that you can create matching accounts/passwords on SME and the client, give them whatever acces you think best, and, if they're in the same workgroup log on one time when booting Win2k, and access what you need from SME with better security, and without further ado.
As far as printing goes, if you really want to do it this way, you should be able to "store" an account\password like this:
Open the Printers window
Hold down the Shift key and right-click on "Add Printer"
choose "Run As ..."
enter "admin" and the password
map the printer in the usual way
Thereafter, anytime you use that particular mapping from an application, you will be printing as "admin" as far as the server is concerned - because Win2k will present the admin logon when requested.
If you try this pls let us know the results.
Offhand, printing this way doesn't by itself seem to be such a big deal, but you might want to consider spending some time investigating the potential security consequences of doing things in this manner.
