One weakness of the Citrix client drive mapping is that you can’t automatically connect a client’s network drives. For some reason, Citrix don’t supply an option to do this, even if you want to - you’re supposed to write a script.

I’ve written the below script in PowerShell that will go through and map all client drive letters that aren’t already mapped. To run it, you’ll need PowerShell installed on your Citrix Servers. Get it here.

Save the below script as “mapClientDrives.ps1″ and execute it via PowerShell. Wordpress is being a pain and not letting me upload the script.

# mapClientDrives.ps1
#
# Maps all client drives in Citrix, including network drives,
# which are not mapped by default.
