I'm running W2K with SP3 and all the fixes except SP4. Whenever I install SP4, IE6.0 takes a long time to get to some pages on the Internet. I am/have run Norton AV, Spybot and use ZoneAlarm behind a Linksys router. Whenever I unistall SP4, everything returns to normal. I can't seem to find a reference to any problems like this. Thanks.
