cannot logon nas home

When I attempt to logon to my NAS (Linkstation) at home Vista askes for user name and password eventhough the Linkstation doesn't have any user accounts or password enabled. Hoping to solve the problem by setting up a user account and password on the linkstation but, that didn't work. When I insert the users name and password then select okay, Vista puts the following in the user name fillin "domain name\users name". I have selected the name of the home workgroup but Vista continues to ask for correct users name and password. I know this is related to Vista being a member of a domian at work. I setup a seperate profile on the workgroup as a test and can access the linkstation wihtout any problems.
Here is my setup:
Have Beta2 installed on notebook which I have joined to Small Business Server 2000 Domian at work on wired LAN. My home network is a wireless workgroup (MSHOME) with a Linkstation (wired) to router. Problem: Vista recognizes the pc's, network printer, Linkstation which doesn't have user accounts or passwords required. I would really like to not resort to using two profiles (one for domain at work and one for workgroup at home) Any ideas how to map the linkstation using the domain profile without Vista mandating users names and passwords.
Thanks,
