upgrading BIND 921 to 932

[simon church]

Hello,
 
we are upgrading our old installation of BIND 921 (windows 2000) to 932 (windows 2003). We have a primary server and a secondary server. I set up a test environment with 921 and some test zones and was able to run nslookups etc to prove that it was working. I ran the install for 932, setting up the local account, changing some file/folder permissions as required. However, I am not able to run any nslookups now.
 
Are there some other steps I need to take in doing this upgrade that I might be missing? Also, when it comes to production, does it matter whcih order I upgrade the primary versus secondary BIND servers?
