There was a python thread on cross platform home directory determination 
listed in one of the Python URL's. It discusses the Windows 2000 issue. 
Here is the code:

def getHomeDir():
    ''' Try to find user's home directory, otherwise return current directory.'''
    try:
        path1=os.path.expanduser("~")
    except:
        path1=""
    try:
        path2=os.environ["HOME"]
    except:
        path2=""
    try:
        path3=os.environ["USERPROFILE"]
    except:
        path3=""

    if not os.path.exists(path1):
        if not os.path.exists(path2):
            if not os.path.exists(path3):
                return os.getcwd()
            else: return path3
        else: return path2
    else: return path1
