12:  * Thought I could help clarify something with accessing network shares on a
13:  * Windows network (2000 in this case), running PHP 4.3.2 under Apache 2.0.44.
14:  * However you are logged into the Windows box, your Apache service must be
15:  * running under an account which has access to the share.  The easiest (and
16:  * probably least safe) way for me was to change the user for the Apache
17:  * service to the computer administrator (do this in the service properties,
18:  * under the "Log On" tab).  After restarting Apache, I could access mapped
19:  * drives by their assigned drive letter ("z:\\") or regular shares by their
20:  * UNC path ("\\\\shareDrive\\shareDir").
