Acceesing python httplib2 over a network share in windows 7

[aj]

I am trying to run python from a network share on windows 7.
The network share is T:

    >t:\python-2.6.1\python
    Python 2.6.1 (r261:67517, Dec  4 2008, 16:51:00) [MSC v.1500 32
bit (Intel)] on win32
    Type "help", "copyright", "credits" or "license" for more
information.
    >>> import httplib2
    httplib2\__init__.py:29: DeprecationWarning: the md5 module is
deprecated; use hashlib instead
    import md5
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "T:\python-2.6.1\lib\python2.6\site-packages

    import httplib
    File "T:\python-2.6.1\lib\httplib.py", line 77, in <module>
    import mimetools
    File "T:\python-2.6.1\lib\mimetools.py", line 6, in <module>
    import tempfile
    File "T:\python-2.6.1\lib\tempfile.py", line 34, in <module>
    from random import Random as _Random
    File "T:\python-2.6.1\lib\random.py", line 871, in <module>
    _inst = Random()
    File "T:\python-2.6.1\lib\random.py", line 96, in __init__
    self.seed(x)
    File "T:\python-2.6.1\lib\random.py", line 110, in seed
    a = long(_hexlify(_urandom(16)), 16)
    WindowsError: [Error 127] The specified procedure could not be
found


When I copy python-2.6.1 to my local drive it works fine. It also
works fine on my windows XP machine using the same network share.
