This one made me swear a lot: http://support.microsoft.com/kb/842136 http://support.microsoft.com/kb/842136 ... remote login to a windows 2003 server changes the default locale, breaking servers that depend on the default locale (which of course they shouldn't!). When this bit us, we were working on the server in a different room from a guy who was very occasionally logging in remotely, as I recall we only realised when he left his door open and we saw the two things happen at once.
