On a 2003 server that has been upgraded from 2000 server (long ago, no problems so far), suddenly several installations that should write into c:\winnt started writing into %homedir%\windows !? %homepath% is c:\documents and settings\username.
The variables are all in the expected state and healthy, that is echo %windir% for example still is c:\winnt
I am really worried why it uses %homepath%\windows - since it is an upgrade, the directory windows has never existed.
Also some applications don't work anymore since they are looking for files in %homepath%\windows instead of c:\winnt.
Any suggestions were to start looking?
