I notice that the nameresolve.com servers returning the CNAME to kissimmee-fl.vts.hosting are also returning an SOA record for "hosting" in the authority section which looks very strange to me. Perhaps Windows is rejecting it as an invalid, possibly dangerous response packet?I think that provided SOA record is a "local" or "alternate" version and its existence is why the nxdomain response is being sent to the windows dns server that accepts it at face value (but does not appear to store it in cache, so this is not precisely cache poisoning)
Oh! I missed that. ns*.nameresolve.com, the authoratative name servers for kissimmee.org, are saying NXDOMAIN for www.kissimmee.org. Any idea what DNS server nameresolve.com uses? Because that's... wow. -Bill -- William Herrin ................ herrin () dirtside com bill () herrin us Owner, Dirtside Systems ......... Web: <http://www.dirtside.com/>
