arcgis 10.0 - Use arcpy.mapping to list broken data layers?

I want to list all the broken links in all mxds in a server drive. But whenever I try I get an error come up. Can someone use a specific example, say the drive is D drive, how would I put it into ESRIs script here:

import arcpy, os
path = r"C:\Project"

for fileName in os.listdir(path):
fullPath = os.path.join(path, fileName)
if os.path.isfile(fullPath):
    basename, extension = os.path.splitext(fullPath)
    if extension == ".mxd":
        mxd = arcpy.mapping.MapDocument(fullPath)
        print "MXD: " + fileName
        brknList = arcpy.mapping.ListBrokenDataSources(mxd)
        for brknItem in brknList:
            print "\t" + brknItem.name

del mxd

Also I'm not used to not having pythonwin, does anyone know where to d/l it? I googled it but it kept telling me to install it from the ArcMap cd (I'm just using a work computer).

Below updated version of the ESRI sample should work. It will recursively search all directories below D: for .mxd files. print their names and if any datalayers are broken print the names of the broken datalayers.

import arcpy, os
path = r"D:"
for root, dirs, files in os.walk(path):
    for fileName in files:
        basename, extension = os.path.splitext(fileName)

        if extension == ".mxd":
            fullPath = os.path.join(path, fileName)
            mxd = arcpy.mapping.MapDocument(fullPath)
            print "MXD: " + fileName
            brknList = arcpy.mapping.ListBrokenDataSources(mxd)
            for brknItem in brknList:
                print "\t" + brknItem.name

To write to a file instead of printing to the console:

import arcpy, os

path = r"D:"
f = open('somefile.txt', 'r')
for root, dirs, files in os.walk(path):
    for fileName in files:
        basename, extension = os.path.splitext(fileName)
        if extension == ".mxd":
            fullPath = os.path.join(path, fileName)
            mxd = arcpy.mapping.MapDocument(fullPath)
            f.write("MXD: " + fileName + "\n")
            brknList = arcpy.mapping.ListBrokenDataSources(mxd)

            for brknItem in brknList:
                f.write("\t" + brknItem.name + "\n")
f.close()
