Accessing Navision 4.0 through internet

Your client has two options and it depends on the functionality that the users require on which option they will opt for:

1. The first option is to make use of Terminal Server/Citrix connections where your client has a central server and users connect to the server using Terminal Services/Citrix. Users will execute the Navision client on the server itself and all Navision functionality will be available to such users, since it is in fact a Navision client that the users runs - depending on the Menu Structure and security of course.
2. The second option is to go for User Portal. User Portal is a Web Based interface with a limited set of functionality, such as order capturing and posting, customer and item management and some production functionality. Only a limited number of reports are available by default. This is a truly web based interface running on Windows IIS, but should your client require functionality over and above what is available standard, be careful and make sure you understand XML, Dataports and Digital Dashboard web parts.

Have fun!

As good as (may be even better then) citrix, but much cheaper ...
