[THIN] Auto-restored client printers

All,

We have a group of external users that keep having auto-restored client 
printers show up in their Citrix sessions to our farm.

I'm not aware of anything in our farm that would create this auo-restored 
client printers (my understanding is that it's a manual process of an 
administrator calling the addprinter function that creates these things).

All these users are connecting to our CAG/AAC/WI setup from the Internet.

All these folks are using passthrough Citrix sessions.  After getting in 
via the CAG/AAC/WI, they launch a published Internet Explorer on one set 
of Citrix servers and then launch additional Citrix sessions to our other 
servers from there.

Here's what I've noticed so far...
All these users are offsites for the same company, so they're all 
connected by WAN links and have access to each others print servers and 
printers.  Although they don't use each others print servers or printers 
and don't have them mapped on their client computers.
These auto-restored client printers are showing up in both the first 
(passthrough) and second Citrix sessions.
Both the client computers and the Citrix passthrough servers are running 
the version 10.2 Citrix client (PN).
All these auto-restored client printers are showing up in the format of 
"Client/WING_unknown#///printerserver/printer" within the Citrix session.
When these auto-restored client printers show up one of them is always 
selected as the default printer.
I've verified that the printers are in the 
HCU\Software\Citrix\PrinterProperties key on the client computer and in 
the server-side roaming profile.  We've tried deleting the entries out of 
the client computer's registry, but they inevitably show up again.
We've tried deleting these printers within the Citrix session using the 
File -> Print dialog box of the application (right-click on the printer 
name and select delete).  The printers are removed for the duration of 
that session, but they inevitably show up again on next logon.
If I logon as one of the effected users on my workstation, I don't get 
these auto-restored client printers.

We've contemplated using... http://support.citrix.com/article/CTX117805 to 
disable auto-restored client printers, but right now we're at CPS 4.0/R03 
and we'd need to be at R05 to do this.

So, does anybody know...
If Citrix somehow identifies which client to use the auto-restored client 
printers with?  More specifically, if I log in as one of the affected 
users and the printers are in the account's roaming profile, why don't 
these printers show up in that Citrix session for me?
If there's a script or something that's creating this auto-restored client 
printers on a different Citrix farm and storing the information in the 
client computer's registry, would/could these show up in a session to our 
Citrix farm?

Thanks,
Tony
