During a client installation I came accross a stumbling block when trying to map a UNC path to a WSS 3.0 document library.

The issue was that I need to batch copy files from one server share directly into a WSS 3.0 document library via the windows explorer view (UNC path).
However, while this works like a charm from Windows XP, doing this from a w2k3 server to another w2k3 server is problematic.
Having tried adding the UNC path mapping using command line: Net use X: \\Server\Site\DocLib, and via windows explorer mapping to: \\Server\Site\DocLib , both returned the error:

System error 67 has occurred. The network name cannot be found.

Since the other common way of accessing this, using the document library GUI and using the Actions > Open with Windows Explorer, failed to activate (as I thought due to the default IE lockdown on a w2k3 server), the following have also been set:

* The user account is a site owner in WWS 3.0 and is in the Power User group on the web server.
* Default IE security lockdown has been disabled on the w2k3 server
* All Active X controlls have been enabled
* The site is in a trusted zone

Still no joy.

After some head scratching & further investigation and eventually resorting to the 'phone a friend' option I was relieved to find that the answer was a reltively simple one:

Start the Web Client Service under services and set it to startmode automatic.
