I have a weird issue going on here on my server. For some reason on some of my computers i have to disable ipv6 to join the domain. Then renable it on the restart. Some computers i dont have to do it and it joins to the domain fine. I disabled IPV6 on my server running the microsoft fix utility and it disabled it from the registry however, it still didnt fix my issue on the client side. Other thing i noticed is i cant do gpupdate from a cmd prompt if ipv6 is disabled on that client others it works with it disabled. Im stumped. All Clients are Windows 7 enterprise 32bit. Any ideas on how to fix this ?
