Question

This query runs fine on my local machine:

strComputer = "."
drive = "C:"
path = "\\path\\to\\local\\folder\\"

Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colFiles = objWMIService.ExecQuery("Select * From CIM_DataFile Where Path = '"&path&"' and drive='"&drive&"'")

If colFiles.Count < 1 Then
    Wscript.Echo "Folder does not exist"
Else
    Wscript.Echo "Folder does exist"
End If

But when I try to query a mapped network drive, the program fails with ‘Folders does not exist’. Yet I am sure it is the correct path to the file.

The only parts that change are:

drive = "Z:"
path = "\\path\\to\\mapped\\drive\\folder\\"

Any clues as to why this would not work?

Answer 1

So to debug this I ran the following:

strComputer = "."
 Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
 Set colFiles = objWMIService.ExecQuery("Select * from CIM_Datafile Where Drive = 'Z:'")
 For Each objFile in colFiles
    Wscript.Echo objFile.Name
 Next

This resulted in the error ‘remote procedure call failed’, which I understand means that the mapped drive does not support WMI.
