James, Sorry for the late reply, I missed this while I was on vacation. WTSLocation is the mechanism that Cerner uses to modify the HKCU logicals (Cerner app settings) and printing environment that need to change based on where a user logs in from. So if you have a user that logs into a device on the 3rd floor, the 3rd floor printers are mapped to the Citrix sessions, and location specific entries (patient list etc) are added to the users registry. If the user disconnected and moved to the 4th floor, the print environment and location logicals will be updated for the 4th floor area. WTS uses a database that lists all of the machine names and their respective printers/backend settings, an agent runs on each Citrix Server. Let me know if you have any additional questions.

Can you tell me more about WTSLocation and why it's needed?

We also have Password Manager 2.5 deployed for about 1500 users (selective enrollment). WTSLocation is a requirement for a successful implementation from a printing and location list aspect.

We are a large health organization in Western Canada (BC), and currently have a Metaframe XPe farm that is hosting around twenty clinical, financial, and business productivity apps. We are about to undertake a large clinical information systems overhaul, using Cerner's Millenium software and have procured additional hardware and licensing for this purpose (details of new and existing farms below). The clinical applications that Cerner is providing will be in addition to existing clinical applications currently published. We will most likely build a separate farm for this install. It remains to be seen whether we use existing build architecture/process (ie. XPe on Win2K), or build from the ground up with Pres Server 4 + Win2K3. We are also very interested in the potential of implementing Password Manager into the Cerner environment, to ease the burden on the clinicians, as well as to automate enforcement of security policy, etc. I'm very interested in hearing any comments you might have re: similar type implementations or installations, including any directions, "gotchas" , glitches, must-haves, etc. Cerner is strongly recommending the use of a product called WTSLocation, which they claim will aid in directing printing and user profile directory management. Any comments on this product and its need?
