[LON-CAPA-users] firewall on student computers

So the problem appears to be the combination of the ZoneAlarm Personal 
Firewall, which MSU recommends and might have included in their Windows 
Resource CD, http://help.msu.edu/ethernet/zonealarm.install.html , and 
the new Windows XP Service Pack 2.

This firewall and the new Windows XP Service Pack 2 Firewall, which 
became available two weeks ago, appear to run interference. Each 
product runs fine by itself, the combination causes trouble.

I have informed the MSU Helpdesk and an entry will be added to the 
LON-CAPA student FAQ. The solution is to switch off ZoneAlarm in the 
presence of the new Microsoft Firewall.

Thank you to everybody who made their computer available. Please let me 
know if this does NOT fix the problem.

- Gerd.
