Hi I am Bharkavi, I tried to install IIS in my system. I am using win xp professional and I tried to install IIS for working asp.net, but it is giving the message "some files on windows xp professional service pack 2 cd are needed. Insert windows xp professional service pack 2 cd into the drive selected." I have already installed service pack 2 and I tried installing some missed dll files , but now it is giving message "unable to copy davcdata.exe".
