Hello:
We are experiencing intermittent DDNS registrations with Windows 2000,
Service Pack 1, clients to BIND V8 running under Solaris V2.6. Below are
snippets from a failing and a successful trace. Note difference between DNS
response packet 55 in first snippet and 60 in the second. Any assistance
would be appreciated.
