Today, one of our internal DNS servers began reporting every host resolution
as an address that has been traced to somewhere in China. We are actively
trying to figure out what occurred. Replacing our actual domain with "test",
here is what we saw in nslookup or regular pings.

nslookup
www.test.com
Click to expand...
www.test.com.test.com (china address)
validhost1.test.com
Click to expand...
validhost1.test.com.test.com (china address)
invalidname1.test.com
Click to expand...
invalidname1.test.com.test.com (china address)

What was happening?

TIA

Try putting a period at the end of the query. Apparently it is suffixing
your search suffix and the period will stop that. Can you post an ipconfig
/all (unedited if you can please) so we can further evaluate your machine's
configuration?

Thanks,
