[Full-disclosure] XP updates breaking dash in domain names?

[Adam Polkosnik]

Hello list,

Just recently I've stepped across a little weirdness. It seems that
all of the sudden XP machines fail to resolve names containg an ascii
character 0x2d or in other words "-".
I.E name resolution for domains along the lines of  one-example.com
doesn't work.
Last time I checked RFC921, 1033 hyphen was legal...

Did anyone else got hit by this issue?


Not that I use XP... The only way I was able to compensate for that
was adding a static entry in system32\drivers\etc\hosts.
