hi  I have been trying to install vista through network (ubuntu hosting the samba share) , The samba share  has no account  (security=share and public =yes as the smb.conf setting) . I can install  vista through the share easily by mounting the share and running setup.exe  . But when I use the  unattend.xml  file (setup.exe /unattend:"Unattend.xml")it give errors.  I checked the error log it said "Cannot access the "<path of image>" using the credentials "<domian\useraccount>" 1. Is it necessary to have <Credentials> tag if the install.win  is not local  but on networkshare(\\networkshare\share install.wim) , if yes , then which credential should I use  since the n/w share  donot require any credential to access it. I have  know clue what should I do , I have tried  everything possible .  plzzzzzz  help. thanks
