Windows Server 2003 does not understand the DNSSEC stuff, nor vanilla 
TSIG. Standard BIND does not understand the Microsoft way of 
authenticating Dynamic Updates (GSS-TSIG), although the modified BIND 
supplied by Lucent in their QIP product supposedly does. So, unless you 
happen to be running QIP, you're probably out of luck for now. Maybe the 
future will see some convergence in this area.
