Mapped network drives

I have this little script that maps network drives for me. I need to change it to also do the following. If any network drive in the 'arrpath' has already been mapped previously then don't map it again. I don't want to finish up having network drives mapped twice.

Thanks
Cheers

Set objFSO = CreateObject("Scripting.FileSystemObject")
arrDrives = Array("G:", "H:", "I:", "J:", "K:", "L:", "M:", "N:", "O:", "P:" ,"Q:", "R:", "S:", "T:", "U:", "V:", "W:", "X:", "Y:", "Z:")
arrPath = Array("transfer" , "admin" , "econtracts" , "hrteam" , "pmp$")
For each strpath in arrpath
For Each strDrive In arrDrives
If (objFSO.DriveExists(strDrive) = False) Then
strAvailable = strDrive
Exit For
End If
Next

Set objNetwork = CreateObject("WScript.Network")
strHomeServer = "\\tyrenet-14\" & strpath
objNetwork.MapNetworkDrive strAvailable, strHomeServer, True
Wscript.Echo "Mapped Drive " & strAvailable & " to " & strHomeServer
Next

You don't care which drive gets mapped to a particular share?

We always reference mapped network drive by the name not the letter assigned to it. So I don't care. I just don't want to see double or triple mapped network drives

I don't know how you're using the mapped drives .. so perhaps this is of little use. Nonetheless, is there any concern about number of connections? If so, here's a way that I use "normal user behavior" to limit the number of connections:

Instead of mapping a drive, create a shortcut on the desktop pointing to the most often used folder. Then, when file access on the drive is needed, just open using the shortcut.
Most people will close the window when they're done - and this removes a connection.
In the right situations, this has very little downside. Only you would know if this helps.

No, I don't want to do that. We have different mapped drives for different users and they are all persistent connections. The modification I need in my script is to check if the name in 'arrpath' is not already mapped before mapping it again.

What I generally do is to unmap the drive and remap it with one script. Seems like this accomplishes the same thing. The downside is if there are potentially active users when the script runs. So your way is better in that regard.

Hi, see how this code goes.

Regards,

Rob.

strServer = "\\tyrenet-14\"
arrDrives = Array("G:", "H:", "I:", "J:", "K:", "L:", "M:", "N:", "O:", "P:" ,"Q:", "R:", "S:", "T:", "U:", "V:", "W:", "X:", "Y:", "Z:")
arrPath = Array("transfer" , "admin" , "econtracts" , "hrteam" , "pmp$")

Set objNetwork = CreateObject("WScript.Network")
Set objExistingDrives = objNetwork.EnumNetworkDrives
Set dctExistingDrives = CreateObject("Scripting.Dictionary")
dctExistingDrives.CompareMode = vbTextCompare
For intDrive = 0 To objExistingDrives.Count - 1 Step 2
	strCurrentShare = Replace(LCase(objExistingDrives(intDrive + 1)), LCase(strServer), "")
	If dctExistingDrives.Exists(strCurrentShare) = False Then dctExistingDrives.Add strCurrentShare, objExistingDrives(intDrive)
Next

Set objFSO = CreateObject("Scripting.FileSystemObject")
For each strpath in arrpath
	If dctExistingDrives.Exists(strPath) = False Then
		For Each strDrive In arrDrives
			If (objFSO.DriveExists(strDrive) = False) Then
				strAvailable = strDrive
				Exit For
			End If
		Next
	
		Set objNetwork = CreateObject("WScript.Network") 
		strHomeServer = strServer & strpath
		objNetwork.MapNetworkDrive strAvailable, strHomeServer, True
		Wscript.Echo "Mapped Drive " & strAvailable & " to " & strHomeServer
	Else
		WScript.Echo strServer & strPath & " is already mapped to " & dctExistingDrives(strPath)
	End If
Next

Open in new window

Hi Rob,

Thanks for the reply. I ran the script.

Your script shows me a list of mapped drives. (as per attahed). One good things is that it didn't mapped 'transfer' again, but didn't map the others from the 'arrpath'

Saviour. You're the man. Thanks. Cheers

No problem. Thanks for the grade.

Just to let you know, it uses objNetwork.EnumNetworkDrives to enumerate the currently connected network drives, that gives you the drive letter and share path of each, as objExistingDrives(intDrive) and objExistingDrives(intDrive + 1) respectively. This is why you have to use Step 2 through the array.

That's how we check the existing connections, and avoid them is one matchs the arrPaths values.

Thanks for the clarification..I didn't know that objExistingDrives(intDrive + 1) will return me the path.
Thanks

There's a good article here on that:
