Hi,
We were in an identical situation and the following procedure worked for me:
- Install the Version 3.10 Navision Attain Client before installing Terminal services on a Server 2003.
- If Terminal services have already been installed, uninstall them and then install the v3.10 client. Afterward you reinstall Terminal services. If you are running Citrix on top of the TS, you better go to the control panel, "Add, Remove programs" and select "Repair" for your Citrix installation, otherwise they wont work properly.
Regards,
Marc
