Citrix Farm and client drive mapping


I am looking to build a small Citrix farm and was wondering what the process was regarding client drive mapping.

From what I understand, unless I disable Client Drive Mapping in the Citrix Connection Tool, clients will have access to their local drives via the Citrix sessions.

Am I correct in thinking that it is best practice to rename the server drives to a letter that clients do not use as shared drives?

It used to be very common practice to re-map the server OS drive to M or some other letter instead of C...but we stopped doing this a long time ago and now prefer just using C.   As you said, client drives get mapped (C on client becomes V in citrix by default). But this does not create many problems because we tell users not to store files on C anyway.  And on the servers, we use GPOs to hide A through D so users dont see them.
The down side is users may need to learn that their C is actually V inside citrix....but the advantage is it is simpler for ongoing maintenance because your citrix INI's and other configutation settings can look more like they would on any other machine, so can end up being a simpler approach to administrer that is easier to maintain.

Citrix Best Practice is to no longer remap the server drives.  In XenApp 5 on Server 2008, that "feature" has been removed.  Remapping drives broke a lot of applications.  Once server drives have been remapped, the only way to reverse the process (for a broken app) was to wipe the server and reload.

You can always block access to the server's C drive thru a Group Policy.  Better yet, use GPDrivesOptions:

Cheers guys

So on XenApp 5, you can no longer re-map the drives? What happens if you upgrade a server to XenApp 5 that already has the drives mapped?

There is NO upgrade to XenApp 5 on Server 2008.  It MUST be a "from scratch" install.  Citrix has NEVER supported an OS upgrade on a server running NetaFram/Presentation Server/XenApp.

Sorry for the typo, that should be MetaFrame not NetaFram.
