Node Alias mapping to a share local to the server fails

We are having a problem where the serer that hosts a Windows share cannot map via \\node-alias\share-name. It prompts for a username\password but it will not authenticate. We are receiving NTLM authentication errors in the security logs. All other servers/PCs in the domain do not have a problem connecting to the share via the Node Alias. This becomes a problem because local DTS jobs have to grab files from a local share to complete. All DNS entries are created and are valid. I believe the problem to be with the NetBIOS and the server not allowing an access token to be created using an alias.

Any thoughts?
