On a number of SBS 2003 boxes I maintain, I am finding that DHCP loses its bindings to the network adaptor every time they reboot. When trying to re-assign the network adaptor, they will not allow it - I put the tick in the box but when I look in there again it has disappeared!
As a work around, I am having to change the servers IP address through server management - then because of the way we have our network I have to change it back again! This only takes 3-4 mins but is annoying. Doing this automatically resets the binding.
Any ideas what is going on?
