Outlook Anywhere on Exchange 2007/Windows 2008

Doesn't work really well out of the box. Why ?

See if you can spot the mistake between these two pictures. One of them is a picture of the IPV4 stack listening and the next one shows the IPV6 stack listening. If you've installed the over HTTP proxy and enabled Anywhere on your on 2008, issue a Netstat -a -n and you' see the 6001, 6002, 6004 ports are listening on IPv4 but not IPv6

I found a terrific write up on this here on Aaron Marks blog. In a nutshell, you're looking to do a host file edit and add your machine name and IPv4 address, plus disable IPV6 in the registry and reboot. Well done again Aaron!
