I'm trying to help my uncle set up his scanner to scan to the network but the damn thing is more stubborn than a mule. Believe it or not for a time I HAD it working, the scanner would upload the scans to a directory on my uncles laptop, but after a while that stopped working and I couldn't get it in a working state again. He has since added a Synology DS211J to his network and I'd like to set it up to scan to there. The scanner is a Brother MFC-9320CW. I've updated the firmware etc. By the way my uncle is running windows 7.

Here is a link to the manuals for the printer, I've looked through them and followed the instructions but this thing keeps giving an authentication error:

Here are two screens from the brothers config page:

Ignore the username field ive tried blank, guest etc. I've tried changing the upload directory to \\scans\ and synologyds211j\scans etc. I would REALLY like to avoid setting up a domain for all this. Can anyone guide me towards how to configure this to work in a workgroup environment? I've spent 4 hours banging my head against the wall tweaking configuration options with no luck.

If the folder located on a server on the domain, you need to have a user that have the permission to write to that folder.

No domain and I don't want to set one up.

Come on, someone's gotta have an idea.
