Case Summary: Zone Alarm disables browser cookies that are required for Web+Center logins to work correctly.
Zone Alarm Firewall may not permit Web+Center cookies from being set. To verify if browser cookies are being properly set, try running the installation configuration test utility called installtest.htm which is located in the techcenter (tech50) virutal directory. On the local machine it can be run by entering http://localhost/tech50/installtest.htm.
If this fails then you must configured Zone Alarm to properly pass cookies to your client browser.
