Eric,

All this time I have been operating under the assumption that WSI is
running a current version of the LDM. Your comment about the request
line caused me to discuss this with my coworker.  I see now that my
assumption was probably wrong.  

No one here really knows for sure which version of the LDM WSI is
running, but if no one is using request lines to receive the data then
they must still be running version 4.  In this case you want the accept
lines and don't need the request line.

I am unsure about how version 4 and version 5 interact.  The one piece I
can think of that might fit the circumstances is that your ldm also
wants to be able to accomplish the forward and reverse name lookup.  Can
you successfully do 'nslookup sysu1.wsicorp.com' and 'nslookup
198.115.158.1'?

If this is not the problem, then I would suggest that you allow us to
login to your ldm account.  I have started working with Tom Yoksas on
this.  If this is ok with you then I would round him up tomorrow and
we'll take a look at it together.

I'm sorry to lead you astray.  This time it was my ignorance rather than
brain explosions of gas.  I hope we can help you get this solved
tomorrow.

Anne
