Yeh, what browser?
Looks more or less normal in Chrome 49 (last version supported on XP). Alignment is a little bit off, fonts and content look fine. The adblocker probably doesn't work as well, that might explain some layout differences, or just that they're using whatever set of webkit stuff is newer than that. Let's see, that's a 5 year old version huh, so probably a few things missing since, current version is 97? Sheesh.
It goes without saying, IE shouldn't be online at all, and with Firefox support ended around a similar time frame as Chrome, the best option is to firewall or disconnect any XP machines you can't upgrade/replace for whatever reason.
