I found a bug. "Release and renew the IP address from DHCP server" option hangs on me because I have VirtualBox Host-Only Ethernet, and that is Enabled. Manually disabling it fixes the problem. Keep up the good work!
Yes they are very good scripts. It takes a lot of hard work to create the scripts and test them to make sure they don't break anything. There is also the UPDATE issue with MS. A good script can become worthless with a code change from MS However the best user friendly script will have DISABLE-ENABLE. and that takes a lot more work.
