Trouble accessing Gmail or internal chat client
I have been in a couple of places which I needed to access my email and chat so here's a little fix to get around evil DNS.
Modify your hosts file to look like the following:
C:\Windows\System32\drivers\etc\hosts
Modify your hosts file to look like the following:
C:\Windows\System32\drivers\etc\hosts
127.0.0.1 localhost
74.125.79.17 mail.google.com
66.102.1.189 chatenabled.mail.google.com #or 74.125.19.189 for non-Comcast.
This basically tell your system where these services are located instead of relying on a third party to instead let you know.
