>Is there an API to map a Windows NT network drive letter? Similar to the NET USE dos prompt command.

In addition to the API stuff mentioned by others, the Windows Scripting Host (native to 98, and addable to other operating systems by running the self-installing WSH.EXE available from Microsoft's Web site) provides a network automation object. If WSHOM.OCX has been registered, the following works:

oWshNet = CREATEOBJ('Wscript.Network')
*  Lots of arguments available here:
*  cLocalDrive is the local resource name (eg 'N:')
*  cRemoteName is the UNC of the path you want to map
*  (optional)  lUpdateProfile (bool) if .T., save the mapping
*  (optional)  cUserId the name of a user other than the default
*              Windows Login userid for accessing UNC
*  (optional)  cPassword password for user accessing UNC
oWshNet.MapNetworkDrive(cLocalDrive, cRemoteName)
*
*  You can unmap a drive by:
*
oWshNet.RemoveNetworkDrive(cLocalDrive)
