When using WinXP system, I didn't had issue with mapping the network drive on windows system, my mac mini or Xserve system. I have installed Vista Home Basic on 3120 to start with and find out that I have difficult mapping the network on my Mac Mini or Xserve. On Mac mini , I can see the under network and ask me for user/pass. inputing user/pass is same as my Win XP since I use different login. By typing same way I do under Vista, it will not take it but under WinXP does work. 3150 RC2 is still the same. I tried xserve any my client place and xserve prompt me with me path not found. although my WinXP was just fine.. Does anyone has issue with mapping the network drive?
