Below is the K5NA configuration that experienced the problem during 
CQWW Phone. We also had failures during SS Phone. The only difference 
between the CQWW Phone and SS Phone here were the use of 7 networked 
computers for CQWW and 2 networked computers for SS Phone. Every 
computer used was running Win/XP.

K5NA Info:

7 - Two were desk-top and the others laptops.

All above 1G speed and at least one as much as 2.6G.

Memory sizes were varied with the largest RAM being 1G The machine 
wiith 2.6G speed and with 1.0G RAM crashed as many times as any of 
the others. Maybe more because it was the center of the network.




All computers running Win/XP at the latest levels.

Mixture. Packet spots were received from an in-house AR-Cluster over 
the local network. The Internet was ONLY used if there were problems 
with the AR-Cluster and we needed an alternate connection path.

Not applicable since I was using no machines at Win/98. We thought 
W/98 was the problem last year when the same thing was happening. 
That's why we switched to using all XP machines this year but the 
same problem occurred.

I plan a single-op assisted this weekend with only one computer 
running a bandmap and I will see if the problem occurs.
