+\S{faq-alternate-localhost}{Question} Since I upgraded Windows XP
+to Service Pack 2, I can't use addresses like \cw{127.0.0.2}.
+
+Some people who ask PuTTY to listen on localhost addresses other
+than \cw{127.0.0.1} to forward services such as SMB and Windows
+Terminal Services have found that doing so no longer works since
+they upgraded to WinXP SP2.
+
+This is apparently an issue with SP2 that is acknowledged by Microsoft
+in MS Knowledge Base article
+\W{http://support.microsoft.com/default.aspx?scid=kb;en-us;884020}{884020}.
+
+For a fix, you'll need to contact Microsoft support, as mentioned in
+the KB article. We've been told that the process is reasonably easy,
+and is free of charge; and that the fix will be included in the next
+Windows XP Service Pack (but probably not before).
+
+(\e{However}, we've been told that SP2 \e{also} fixes the bug that
+means you need to use non-\cw{127.0.0.1} addresses to forward
+Terminal Services in the first place.)
