[WriteLog] Need Help with Networking "Lost connection to ..."

[k6ufo at arrl.net]

I'm trying to link two computers in a network for 
Sweepstakes, but they never seem to connect and I 
get an error message "Lost connection to K6SU"

Both computers are Windows XP with short, all 
capital letter names (NN7SS and K6SU), same workgroup 
and identical user accounts and passwords. File and 
Printer sharing works as I can see, open and copy 
files back and forth to the other computer's Writelog 
folder. I opened the Windows Firewall to Writelog.

But in Writelog, after I "Register to accept network 
connections", when I try to "Link to Network" I get 
about a 10 second delay and then a Writelog Networking 
window that says "Lost connection to K6SU".

I've searched the archives, and checked what 
could find there, like "nbtstat -c" does show the other 
computer.

Help! Any ideas?
