I was wondering if there is a better way for detecting the presence of the LAN (Local Area Network)?

The following is what I am using right now to detect whether or not a certain drive letter, folder and subfolder exist.

* Detect the presence of the network.
IF DIRECTORY("E:\MSDS\DATA")
  oApp.NetworkPresent=.T.
ELSE
   oApp.NetworkPresent=.F.
ENDIF
