In Windows Server 2008/7
Control(Panel) (WIN+R)--> "Clock, Language, and Region" -->
Change Location --> tab "Administrative" --> under "Language for non-Unicode programs" click "Change system locale.." --> choose from drop-down-list "Danish (Denmark)"
Don't confuse it with "Currebt location:"
under "Location" tab which is still "United States" if you have servers in US language.
This is in Windows Server 2008. There are some small differences in other Windowses. For example in Windows XP:
Conttrol Panel==>Regional and Language Options==>Advanced. ==> Language for non-Unicode programs
Write here if this helped. There are other options depending on whether I correctly grasped the context of your problem
