Can A Network Drive Be Mapped to a Folder Residing on Different Subnet?

Client/Server Database App needs moved from current LAN file server to a web server in DMZ (to enable theWeb Access application module).

However the locally installed application client currently accesses the database on the LAN file server via a mapped drive created within XP's "MY COMPUTER" window.  (The file server is an Active Directory member like the XP machines running the application client).

If I move the database to a standalone (non-member) Web server in the DMZ (i.e. different subnet) then I can't map a drive to the folder where the database is stored, can I?  Doesn't XP only let you map drives to folders residing on computers within the same network, correct?

Try re-mapping the drive using the IP address of the server.  Does this work?

Browsing My Network Places requires the use of NetBIOS (broadcast type) traffic, which is unroutable.  Thus, it cannot span multiple subnets on it's own.

if you know the IP address and have appropriate permissions you can map a network drive on the other side of the planet if you wish

OK, I see more now after reading your responses & looking closer...

XP "Add Network Place" Wizard indicates I can map to a "Web share" on a remote server.
So first step is to config IIS on Web server in DMZ to publish the folder containing the Book Systems database as a shared Web folder (but I will try to limit access to the 3 library Admin computers).

PIX is no problem.  I admin the PIX & in this case the computers needing access to the folder in the DMZ are located behind the higher security LAN interface so their traffic to DMZ is allowed by default.
