I want to restrct users from modifying the access applications. Many users have microsoft access on their computer so it isn't any problem for them to open the application frontend, and change the forms, or create new ones or even copy the app to their hardrive, modify it and link to the backend which is on the server. I was thinking about putting the application in a citrix envoironment but everything I read on the internet says that it is difficult to do and doesn't support multiple users very well. The big thing about citrix is the users only get a screen shot and are then unable to copy or modify anything. We have about 180 access applications in 97, 2000, and 2003 versions Any advice would be appreciated.
