Windows 2000 Deep Mapping

When defining a Windows 95/98/ME/NT4/2000 network shared resource
("a Share"), it can be accessed via the "Network Neighborhood" /
"My Network Places" and you can create a virtual disk-drive via
Network drive mapping

In previous version of Windows (95/98/ME/NT4), a shared network
resource can only be mapped at the share-point, not at a position
deeper in the directory structure inside the shared section of the disk.
Windows 2000 mapping supports now deep Mapping.

Standard mapping:

There are several possibilities to create a
network drive mapping:

-select fist the object, then request the action
Browse the "Network Neighborhood", select
the system on the network, select the shared
resource and then via a right-click define to
map this shared resource as a network drive.

- select request first the action, then select
the object

Right-click on "Network Neighborhood" or
on "My Network Places" and select to
"Map Network Drive"

On Windows 95/98, you can just select the
drive character to be used and enter the
network path as UNC:
\\<computername>\<shared resource name>
Windows NT4 allows via a browser to
locate the shared resource and creates the
UNC network path based on your selection
- Command prompt via NET USE

When systems are connected to Windows
NT-servers, network drivers are often
created via the "NET USE" command,
which is defined in a logon-script executed
during the network logon:
NET USE <drive:> <UNC>

When attempting to map a network drive
at a directory inside the network share:
NET USE <drive:> <UNC>/<path>
then Windows 95/98 (on the left) and
Windows NT4 (below) display error
messages, since this feature is not supported.

Similar to the mapping support on Novell Netware servers, Windows 2000 supports
"Deep Mapping": to define as map-point any directory inside the network share:

Make a right-click on
"My Network Places"
and select :
"Map Network Drive.."
You can enter the UNC of the
folder to be mapped or
(much easier) use the
button "Browse" to locate/
select the folder.
You are able on Windows2000
to select a directory / folder
(not just a Share-name)
The UNC is now:
This extended UNC can also be used
with the NET USE - command on
Windows 2000 systems in a
Command-Prompt Window:
NET USE <drive>: \\<server>\<share>\<path>
