How do I add a network user into my file permissions?

Question

I have a folder (in particular, a "User Home" folder) that I would like to give access to a local account.

For example, My laptop's local name is called "PC", for some apparent reason. It is also connected to a network called "NETWORK". It's configured to have both local and network accounts.
Of course, those aren't the actual names of the network/computer.

So, how do I add a network account into the file permissions? I am connected to the network and only my PC shows up as a possible network object.
(Yes, logging out and using [Network Name]/[Username] for login does allow you to log in with a network account).

EDIT: Basicially - Why can't I add my network profile onto the permissions list (while logged onto the local profile) THUS while I'm on my network account - why I can't add my local account into the permissions list?

Answer 1

It appears that by "network" you really mean "domain"? If you are in a domain, you can grant access to domain accounts by entering them as

domainname\username

for example, NTDEV\davec

You enter the account ("object") name by typing it, just as above, into the "Select User or Group" dialog and and then clicking "Check Names". If it's ok, your entry will suddenly be underlined. OK from that dialog and then set the permissions (access rights) you want to grant, OK out, etc.
