Bogus Update errors in BIND 8.1.1?

[Treptow, Craig]

Hi.  I'm running BIND 8.1.1 on AIX 4.3.1 and testing with W2K machines.  While
installing and configuring the W2K servers, they attempt to register names.
These generate error messages such as:

27-Feb-2001 20:44:39.744 update: error: error processing update packet id 2993
from [192.168.40.106].1067

I have also captured some of these with a sniffer, and the attempt to register
a name is replied by the DNS server with a status of OK.  I also find the
entries it was trying to register in the DNS zone files...such as:

$ORIGIN _tcp.Default-First-Site-Name._sites.dc._msdcs.root.principal.com.
_ldap   600     IN      SRV             0 100 389 dom2.root.principal.com.
;Cl=4
        600     IN      SRV             0 100 389 root.root.principal.com.
;Cl=4

So, since the updates appear to actually have worked, does BIND 8.1.1 display
bogus error messages?

Additional info:

Some of the packets containing the "register name" operation were flagged by
the sniffer with "DLC: --- Frame Too Short".  Others had "Name = ERROR to
converting names", "Type = ?", and "Class = ?".  Could these be related to the
errors from the DNS server?

I have BIND 8.2.2-p5, but have not yet had a chance to test this with that
version.

Additional Questions:

Will RFC 2136 show me what dynamic update conversations are supposed to look
like?

Thanks.
