You may have found then when you launch a Citrix session inside a Citrix session that the local drives do not map through, this does not change no matter what client drive redirection policy you set.
As an example if we have a user who has a laptop and they launch a Windows 10 desktop through Citrix into their corporate network, then within that session open a browser and goto a partners Gateway and launch a session there using the Citrix Workspace app installed within the Windows 10 VDI. If the partner environment has client drive redirection set to “allowed” this should map the Windows 10 VDI’s drives through. This of course would map correctly if a session was launched to the partners environment directly from a laptop however drives will not map if a session is detected as running inside a session. At least not by default.
In order to enable this capability the following registry key needs to be updated within the Windows 10 VDI’s Citrix Workspace registry location:
HKLM\Software\Wow6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\ClientDrive
NativeDrivemapping Reg_SZ TRUE
You can also combine this with targeted Group Policy Preferences or ivanti conditional actions etc to ensure that this setting only applies to the groups/users that need the access.
Once this has been completed then a parent Citrix session with this value will be able to map client drives through to child Citrix sessions if the target environment allows.
