Please help I have been at this all day!

I set up my new Patriot Corza NAS and got it running despite some ambiguous instructions on my Win Vista Home Premium 64 computer. I kept the standard defaults ie name: corza-nas, login: admin, password: admin etc. The 2 808GB HDD's are set up in ext3 as raid1.

Following comments by another user I typed \\corza-nas in the address bar of explorer, right clicked the public folder and mapped this to G: drive.



Everthing worked fine, I was able to copy, open files etc but every time boot up from windows I get the mesage "could not reconnect all network drives".

The corza icon has a red cross through it and clicking it requires me to log on again. When i do this the username comes up as "k1200\\admin" (the computer name is k1200) which I have to change to "admin" and then enter "admin" as the password, everything works fine again.

I have read through this and various other forums but am unsure of this question. Do I need Vista Professional to stop this from happening? Keeping in mind that I dont have (or want) any users on my computer, it just boots up as administrator straight to the desktop.

Thanks
