Just wanted to supply more information in case it might be useful.
Using one ISPs nameserver (I2Bnetworks, 18.104.22.168), if I ping a host in
this troubled domain (www.sandicor.com), it takes a long time in between
pings to resolve the name. For 3 pings, it is taking 20 seconds. If I
ping with the -n option, works just fine.
If I immeadiatly ping www.google.com, works perfect. So now I am really
suspicious of something in my zone file, or the configuration of the
If I switch to another ISPs nameserver (hosting.com,22.214.171.124),
everything works fine for the domain.
We are having users calling in from other (seemingly random) domains,
that can't resolve our hosts period.
