DFS share to non-domain computers

Hi,

How do I give non-domain account access to dfs share folders? I have the main root, lets call it mydomain\main. The main dfs root is on server A. The non-domain computers can access that just fine. The problem I'm having is with the links that's is on another server (server B). The non-domain computers can go into the dfs root just fine but when they try to go to a dfs link within the dfs root they get the following error: "X: drive is not accessible. Logon failure: unknown user name or bad password."
I've checked on the security and share permissions and everything looks exactly like the main root. What am I doing wrong? Can someone help me resolve this?
