[Samba] Error joining Win2K domain: ads_connect: DSA is unavailable

I had changed my administrator password on the Win2K server prior to doing the "net ads join".  'kinit administrator at MNU.EDU' is successful.  I went ahead and pulled down the krb5-current snapshot from MIT, and samba3.0alpha wont build with it.  30 some lines of errors when 'Linking bin/smbd', if anyone is interested.  Looks like brokenness in krb5 though.  Is there a snapshot out there known to work with samba+win2k kdc?  Or any other idea?  Is there no one running samba as a member in a Active directory? :)

You have not got the latest MIT kerberos (you need a snapshot, the 
releases don't seem to support it) and your Administrator password
has not been changed since you upgraded to ADS.  As such the only
password is the MD4 based password from pre-ads, which MIT can't 
use.
