Hi Marvin,
I've noticed when performing NSLOOKUP with set type=all on
www.nusolutions.biz the IPv6 listings.  Yours is one of the first
that I've seen. I'm sure there are others out in the wild using that
version of IP.  What you might want to do is make sure that your gateway
has 
the right external DNS servers listed.

Another test would be to use http://www.dnsstuff.com so you can see
the external tests from a different point of view.

Have you looked at any of your HTTP log entries?

Joseph

Not me Tom. I'm www.nusolutions.biz and it's published at
70.148.240.122.
Tracert for me shows: 

H:\>tracert www.nusolutions.biz

Tracing route to www.nusolutions.biz [70.148.240.122]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  10.1.17.254
  2     1 ms     1 ms    <1 ms  208.62.73.254
  3     *        *        *     Request timed out.
  4     *        *        *     Request timed out.
  5     *        *        *     Request timed out.
  6     *        *        *     Request timed out.
  7     *        *        *     Request timed out.

The domain hasn't expired and I can browse it locally on my web and
desktop systems.
The SSL Cert for OWA is also fine as I can log in to the mail server
without a problem.
