New Post: Error running AutoSPInstaller and creating Web App

Hi,

I am running SPInstaller to set up a multi tier farm but the script keeps failing with the follow error message. I have tried to change the site collection but i am still running into the error and not sure what i need to change in the script to get past this point.

• Creating web applications...
• Web app "SharePoint - Portal Sites" already provisioned.
• Setting up managed paths for "http://portal.virtualworks.com:80"
• Setting up explicit managed path "portal" at "http://portal.virtualworks.c
  om:80"
• Done setting up managed paths at "http://portal.virtualworks.com:80"
• Granting VIRTUALWORKS\sys-D-Farm rights to "SharePoint - Portal Sites"...D
  one.

- Creating Site Collection "http://portal.virtualworks.com/"...

• Script halted!
