Okay, the TXT record is not one I've encountered before but the CNAME/A
records match what I know IE8 supported.

Does the wpad.xxxx.xxx:80 server provide the wpad.dat file with the
correct mime type "application/x-ns-proxy-autoconfig" in HTTP response
message?

Does the wpad.dat file contain valid PAC syntax pointing receivers to
use the proxy?
 <http://findproxyforurl.com/> has more info on what the PAC file needs
to contain.

What OS is the client machine using?
 Presence of IE 8 hints that it is an older one (XP?) where there may be
ipconfig related tricks needed.


If you have not already done so that site also has troubleshooting tools
and how-to at <http://findproxyforurl.com/troubleshooting-pac-wpad/>.
