Thanks - That points in the right direction I want to go.

However I just ran into a wall with it. Disk Management reports the drives (E;F;G;H) as being assigned. However Windows Explorer does not. Therefore, the

if exist f: net use n: \\unc\share

I had planned to use won't work.

Wouldn't this result in the shares being double connected to, but as a new letter each time?

Why not just disconnect the share with

objNetwork.RemoveNetworkDrive "M:", TRUE, TRUE

And then let the script remap the drive to the original letter?

I don't think it would double map. If the drive does exist, then map it as N, otherwise it would / could map as F.

Not as in double like that but to explain

M: is mapped to datashare1
login request hits
M: exists ok, go map the datashare1 as N: now.

momurda

I think the first M: would be an empty sd card reader or something similar
It exists, so the network share would be mapped to N:

Least that is what I imagined he wants to do.

Right, however in this case it would be

F: = CompactFlash drive
F: exist, map datashare as N:

Exactly

So is the goal here to just always map the share and not care about the drive letter?

Preferably not. But in some cases, you have to adjust the company standard until the standard is changed. If you have a standard of:

F: = \\unc\shared
H: = \\unc\home

Since E-H are the Media bay, they can't be used as the company standard, so, new script for those (few) computers with media bays to move the SHARED and HOME drives to available lettes.

Is the compact flash drive or other empty media card drives ever going to be used?
Some of the computers here have them, but ill be damned if I have ever seen one in use. We do use portable usb with CF or SD slots in them, but the ones built into the case are never used I think.

If the situation is the same wher eyou are, I think you could delete them if they exist (if exist m: net use m: //delete) then map the network drive normally. Or you can use GP to replace/update drive letters

You could delete them if they 'existed'. Windows Explorer does not list them. But Disk Management does.

One option mentioned was to disconnect them if not to be used... problem solved.

Yea you could just unplug the usb header on the mobo.

This or find the powershell script and object names that allow you to find remove the drive letter mapping.

All of this seems like a lot of hard word versus (with management approval) an email stating -

Starting tomorrow, what used to be the F: drive will now be mapped as the P: drive and what was the H: will now be the R: drive.
Please be aware that any scripts currently using the F: or H: mappings will need to be updated to the new location. Instead of using P: or R:, please use \servername\sharename1 for P: and \servername2\sharename2 for R: This will prevent you from having to update these scripts in the future in the event that these drive letters will need to change.

-IT.

@Dashrender I agree, yet still don't understand the reason for using drive letters in the local drive space that is normally accessed by windows when connecting local storage.

Start from Z and go backwards for any shares.

It's not greenfield, I'm sure Gene is working from a setup someone else built 15+ years ago before PCs came with all those stupid memory card slots that suck up a letter but don't map into explorer like he mentions.

I'm sure it was setup longer then 15 years ago sadly.

How about this to get all drive letters in use?

for %i in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do @%i: 2>nul && set/pz=%i <nul

GPP can be set to use the next available drive.
