<DIV>Hello,</DIV>

<DIV>I'm getting what appears to be a common "error (unexpected RCODE REFUSED) resolving" error. My research has lead me to disable IPv6 when starting the named service with "<SPAN style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 12pt; mso-fareast-font-family: 'Times New Roman'">named -4" as it could be related to IPv6 broken connectivity (of which we been actively deploying and testing). This has taken away the AAAA log activity but I still get the error:</SPAN></DIV>
