iPhone Linker error : Command /usr/sbin/chown failed with exit code 1
===

I am getting a linking error when I try to archive my app. The brief description of the error is 

    `Command /usr/sbin/chown failed with exit code 1`

The detailed description is 

    SetOwnerAndGroup "r499908:US-ADdomain" users /Users/r499908/Library/Developer/Xcode/DerivedData/W-akvlnuynzzkjqwcmnnsmrpjpgqfs/ArchiveIntermediates/Advisor/InstallationBuildProductsLocation/Applications/W.app
        cd /Users/r499908/Desktop/Projects/JPMorganFunds-Advisor-1.4
        setenv PATH "/xcode4-gm/Platforms/iPhoneOS.platform/Developer/usr/bin:/xcode4-gm/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin"
        /usr/sbin/chown -RH "r499908:US-AD\\domain users" /Users/r499908/Library/Developer/Xcode/DerivedData/W-akvlnuynzzkjqwcmnnsmrpjpgqfs/ArchiveIntermediates/Advisor/InstallationBuildProductsLocation/Applications/W.app
    
    chown: US-AD\domain users: Invalid argument
    Command /usr/sbin/chown failed with exit code 1

Is this because US-AD\domain has a backslash as opposed to front slash? If yes how do I correct this?
