I have checked the registry and these keys/values exist as you have said. Curiosity made me check permissions, which resulted in the following message "The permissions are incorrectly ordered, which may cause some entries to be ineffective. Press OK to continue and sort the permissions correctly, or cancel to reset the permissions." However, it reported this same error on the Citrix Datastore and IMADirectory keys. I clicked OK on this and have now tried the ODBC DSN for different users and this now works fine. Why there was an issue on the registry I do not know. This is the same on all of our servers in the farm. Thanks for your help.

Adding it to System DSN has always worked. Do they show up under HKLM\SOFTWARE\ODBC\ODBC.INI (as keys) and HKLM\SOFTWARE\ODBC\ODBC.INI\ODBC Data Sources (as values)? _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of IT Support Sent: Tuesday, November 01, 2005 12:11 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Adding ODBC data sources in MPS4 Hi Need to add SQL ODBC data source (to our Navision SQL Server) for all users in MPS4 for each server in our farm. However, adding either a User or System DSN (with or without change user /install) when logged in as administrator does not populate the data sources that users see. In fact, it only seems to be local to the current user, i.e. administrator. Can't seem to find Citrix app notes for this and trawling the web doesn't come up with much. There must be many Citrix installations out there that use ODBC data sources, so I'm surprised to see the lack of info about this. This seemed to work ok in Metaframe XP ... Thanks in advance.
