You can try using kfNsLookup() if you install the Kixforms DLL. There's also a nslookup() UDF that uses WSH to capture the results.

I think both are posted here, and are in the Resources/KixUDF section of my web site. The kf version is similar, but is more silent than the nslookup(), which sometimes pops up a brief command window.
