I cant add a user from another computer to my security tab Group or
user names box, why might this be? This computer and the other computer
are both part of a workgroup.

Ive follewed the following instructions from MS but am unable to choose
the other computer's users.

"Set, view, change, or remove file and folder permissions
To set, view, change, or remove file and folder permissions, follow
these steps:

Right-click the file or folder, click Properties, and then click the
Security tab.

· To set permissions for a group or for a user that does not appear
in the Group or user names box, click Add, type the name of the group
or of the user that you want to set permissions for, and then click
OK."

The option to Add users come up but I cant add users from my other
computer.

Since you have access to the Security tab, it would appear that
you've disabled Simple File Sharing. Disabling SFS means you
need to create accounts on your computer that are identical in
user name and password to the accounts of the users on the
other computer. If you had left SFS enabled, users would have
used the credentials of the Guest account to authorize access
to shared resources on your computer.

Keep in mind that in a workgroup, all user accounts and groups
are local. Authorization for access to resources are handled by
each computer. The reason why you can't find the users on the
other computer is because they don't have a local account and
thus aren't members of a local group. What you're looking to do
is only available in a domain with a server running Active
Directory. You would then be able to add domain users and
groups.

You may want to do a little more research on the subject of
file sharing.Here are a couple of articles that you may find
helpful:
