This can be done with a simple batch file sensor.

Create a new file in the \Custom Sensors\EXE folder of your PRTG installation called FolderCount.bat and paste the following code:

@echo off
if .%1==. goto noparameter
if not .%2==. goto tomanyparameters
if not exist %1\nul goto notexist

FOR /F %%A in ('dir %1 /A:D') do set count=%%A
set /a count=count
set /a count=count-2
echo %count%:Folders
exit 0

:noparameter
echo Please supply a foldername.
exit 2

:tomanyparameters
echo Your foldername contains spaces, please enclose your foldername in double quotes.
exit 2

:notexist
echo Folder %1% not found.
exit 2

Now create a new custom sensor, select FolderCount.bat and provide the root folder in the parameters section of the sensor.

That means that the server\folder name cannot be found. This can be a rights issue, your PRTG server running under the system account might not have access to this share. Also keep in mind that if your server\folder name contains spaces, you will have to enclose it in double quotes, so servername\d$\folder 1 becomes "servername\d$\folder 1"

I have added some extra checks to the code in my original post.

Still having a little trouble... Should be formatting the parameter like so?
servername\d$\folder123

I can UNC to the folder just fine from the Probe and Server.

Anything that words with the dir command will do, but keep in mind that your PRTG server runs as a service with credentials that might not have access to the folder.

In your case, using an administrative share (d$) that is only visible for administrators, your PRTG server running on the local system account will not have acess to this share.

How can this be solved?

1. You can try to not run the sensor in the security context of the probe, but the security context of the parent device (see the sensors settings page). You will need to supply windows credentials to the parent device for this.

2. Install a remote probe on your "servername". This remote probe will also run on the local system account, but will have access to the D drive. In this case you will have to use "d:\folder123" as parameter ant NOT use the d$ share.

3. Another way is to make a (real) share for the "folder123" and create a PRTG user in your network that has access to this share. The next thing to do will be running your PRTG server with the credentials of this PRTG user.

4. Quick and dirty: Run your PRTG server service with admin credentials. Note: this will bring up security issues and is not recommended for production environments.
