I've succesfully configured DHCP 252 option and tested autoconfiguration for TMG client running Vista and 7. It works fine.
However, when I try to test the same in a XP SP3 computer it doesn't work at all.
By now, I cant use DNS WPAD record since we have a very large domain with several branches, and each one should use a different proxy.
Any advice will be welcome
Thank you for the post.
