No, Ace Ventura hasn’t started writing knowledgebase articles, it’s the advice given about an issue with redirected folders in Windows Vista and Windows Server 2008. I haven’t seen this myself, but fortunately there’s a better workaround than waiting 12 minutes.
Folder redirection does not work correctly after you restart a computer that is running Windows Server 2008 or Windows Vista
The article has some detail about why this happens:
Windows Server 2008 and Windows Vista use the Well-Known folders feature to determine the location of folders in the user profile. By using this feature, Windows redirects Well-Known folders to other locations as needed. Specifically, Windows Explorer queries the Well-Known folder GUID. This query returns the actual folder location, whether on a hard disk drive or on a remote server.
Windows Explorer optimizes Well-Known folder lookups by caching the Well-Known folders and their locations. Queries are performed against the cache, and the location is then returned to the application or to Windows Explorer.
When you use folder redirection, you receive the folder redirection settings from Group Policy. This process cannot occur unless the Workstation service has started. If the Workstation service has not started, the Well-Known folder cache is unavailable. This causes queries for redirected folder locations to fail. Additionally, the cache remains unavailable until the next update. By default, this cache is updated every 12 minutes (after the cache is first initialized and built during logon).
This:
is obviously not the case:

Instead of waiting for Citrix to support Windows Vista icon sizes in their new beta client, I’ve updated it myself. I’ll bet the Mac OS X client gets a full size icon (Leopard supports 512 x 512 pixels). Why does Vista have to be a second class citizen?
Here’s the before and after shots:
I’m sure you’ll agree that ‘after’ looks much better. The crazy thing is that I’ve added the 256 x 256 PNG file that I originally downloaded from the official Citrix blogs site (I’ve lost the original link).
You can download the icon from here and update your existing shortcuts or break out a resource editor to update the executables directly. Here’s the original PNG file if you want to cook your own.

I’m going to try to be optimistic and I know this is a beta product, but I’m not going to bet on Vista icon support in the final release.
I’ve seen some Visio resources popup around the place recently and though that these were worth sharing.
