This has me baffled. At home, I subscribe to Comcast Business HSI. My work which is about 5 miles away is also on Comcast HSI. In the past week we put in a new server which included the most recent version of Exchange. I immediately noticed that after this was done I was no longer getting work emails on my phone when I was at home on WiFi. I would also try to log in to the Outlook Web App on my computer and I would get a server not responding.
I called our contract IT support and they said all systems were up and pingable. I noticed a pattern over the next couple of days that as soon as I left the house, my work email would update on my iPhone and realized that there was something going on with the Comcast network. For some reason once we put in the new server I was no longer to reach it from my home. When I turn on my Witopia VPN from home, I can load the OWA server just fine but as soon as I turn it off and try and go through Comcast, it errors out. Has me stumped. Any ideas?
