Can't get Win2k/NT/XP service working

[m3nth]

I am trying to create a service and have followed the example here:

http://zone.ni.com/devzone/conceptd.nsf/webmain/A9B2FA96B851394586256B26006ECB98?opendocument

This question may actually be more related to VI server's however, I'm not sure.

I have recreated the files per the tutorial. In the GetCookieClient VI, with the CookieService program running in the background, I can successfully execute and get Fortune of the Day, so long as I replace the "myserver.natinst.com" with "Localhost" or "127.0.0.1"

My problem is trying to use my actual machine name, so that this code may actually be used across the network. I am at a loss why I cannot use my Host Name or IP address with this code... below is a summary of my re
sults:

"Localhost", "127.0.0.1" -- Works
Resolved IP from IPConfig -- Error 63, The network connection was refused by the server.
Host Name from IPConfig -- Error 66, The network connection was closed by the peer.
Host Name + Connection-specific DNS Suffix - Error 66, The network connection was closed by the peer.

If I resolve "Localhost" to an IP, then the IP back to a string (using the LV network functions), I obtain the Host Name + Connection-specific DNS Suffix.

Any ideas why I can't just plug my machine name in and have it work?--why it wants "Localhost" or "127.0.0.1"? I would eventually like to try calling my service from a different PC, but if my own PC can't even access itself... well... I don't think I'm going to get very far elsewhere.

Have you made sure to enable other IP address ranges in the VI server
section of your application ini file. I believe that by default VI
server only accepts local connections and evethough you are using your
own public IP address, this is not really a local address in the most
strict sense.

To add other IP address ranges you can best go in LabVIEW into
Options->VI Server and add them there and then copy those entries from
the LabVIEW.ini file to your application service ini file. It is not a
good idea however to add full access to * to this list if your computer
is possibly accessible from public internet.

It's on an internal network and I'm just testing out creating services. Current properties on the CookieService are:

+*

I will go back and attempt to add specific flavors there and see if it recognizes things.
