[RESOLVED] Writing File To A Network Mapped Drive

[ARPRINCE]

My project requires to create a text file on a certain drive. Initially when testing, the file is being written on C:\DOWNLOAD which is the local folder in my IIS server. Everything is OK.

For production, I proceeded to create a MAPPED NETWORK folder \\[Computer]\DOWNLOAD to dump the file and this is mapped in my IIS server as U:. When testing the project, the file is not being written to mapped drive U:\DOWNLOAD and upon debugging, it shows that the directory does not exists.

Why can't I write to a mapped drive? TIA

        Dim dirINFO As DirectoryInfo = New DirectoryInfo(dirUP)
        Dim txtFileName As String = GetTheFileName()
        If dirINFO.Exists = True Then
            dirDUMP = dirUP & txtFileName
        Else
            dirDUMP = dirDOWN & txtFileName
        End If
