access denied

Archived from groups: microsoft.public.win2000.security (More info?)

while attempting to print from command pmompt if I type
the following:
Print filename.* I get the following message
unable to initialize device PRN

If I type:
dir>lpt1 I get the following message
Access is denied

Is this some sort of security/permissions problem? I am
logged on as adminst with full rights. Also how do I set
permissions/access rights for my whole computer and all
folders without having to set sharing for each individual
folder one by one? Thanks in advance once again!!!!!
