I went to the Mac Filmmakers meeting (as I usually do) at Apple headquarters last night and brought my PC. After being chewed out for having a PC on Apple property, I attempted to use their WiFi in order to check my companies' e-mail access. Explorer worked and I was able to log onto the companies' website but was not able to get into their exchange server. Later in the evening, I hooked up to my dial up at home and was able to log into my companies' e-mail exchange server. Was the reason I was not able to log in have to do with WiFi or Mac or none of the above? Please let me know. I will also try the WiFi sometime soon at a coffee house to see if it is just an Mac issue and not WiFi.
