Error - 932 when remote program linking

I’m simply following the sample code in Apple’s own AppleScript Guidebook for performing program linking under OS 9 and I get the error code - 932 (which I can’t find in the docs).
I’ve gone through and setup my computer and the target computers TCP/IP per the instructions and tried this simple script:

set remote_Finder to application “Finder” “eppc://”
using terms from application “Finder”
tell remote_Finder
end tell
end using terms from

When I run the script, I get the error - 932. If I change the URL to my own computers IP address, it works fine! Any ideas anybody?
Many thanks!
