Hello - I have been using ZoneAlarm Security Suite for quite some time now. The problem below had happened to me ONCE EARLIER and it had caused me to actually un-install and re-install (from scratch) the entire product! As such, I was VERY, VERY skeptical of doing (what is below) again, but my work forced me. Bingo: I have the same problem again! THERE IS DEFINITELY AN ISSUE WITH THIS PRODUCT. The last time, technical support just sent me the details of how to un-install completely but they never acknowledged it is an issue.
Due to nature of my work, I had to enable TCP and UDP outgoing + incoming ports of 21, 22, 23, 5800 and 5900. I opened the product, went to Firewall, then custom and ticked the associated checkboxes and give the port-numbers as above. Closed the product and initiated surfing. Problem (a) : The ports DID NOT OPEN UP. Double-checked by booting and opening the relevant screen and found the items to be ticked with the correct port numbers listed.
Finally, I CANCELLED THESE SETTINGS, i.e. removed ANY CUSTOMIZATION (which includes un-ticking the checkboxes and removing the port numbers) and again rebooted the machine. AND ALL **bleep** BREAKS LOOSE - READ ON....
Internet AGAIN becomes intermittent. Open Firefox or IE - I can surf 2 to 3 sites and BINGO, connection disappears. How to establish? Open ZoneAlarm - set Firewall settings to LOW (effectively no firewall)... try again - bingo: works!. Again , works for a few sites and then same problem re-appear, i.e. no connection. What to do? Slide the Firewall settings back to HIGH (for Internet zone, always).... again sites start to work! That's how I am right now surfing the Net!!! Un-believable!!
So: My advice: DO NOT, EVER give any additional ports (i.e. open ports) through customization. Once you do it, even if you remove, press Restore to Defaults, etc., etc. ---- it does not work anymore. Even AFTER you stop ZoneAlarm either completely or just the firewall, Internet connection through ANY web-browsers (tried through IE 6.x and Firefox) does not work.......
I tried to completely stop ZoneAlarm and then try before boot of machine / after boot of machine. DOES NOT WORK. Here's for the ZoneAlarm is too good fans - I press Browse button and THEN do the High to Low or Low to High Internet zone setting change... pages instantly appears.
I am using Windows XP Sp-2 on P-4 with 2 Gb. RAM. ~~ Plz. don't revert back if you're having options (a) Re-install Zone Alarm (b) It's a SP-II problem.
