The Nuance Mangement Server will look to match up the user logged in and the PC to ensure they've successfully been through the audio setup process before for that workstation/VM. Nuance claims this is the best way to ensure quality control and prevent problems in mic funtionality/quality. You can turn this off, but only for the entire dictating environment and it's not recommended.
What drives this match up of user ID and PC, I'm not 100% sure. I do know if you look at documents and settings, USER LOGGED IN, app data, nuance, naturally speaking 10 there's a file nsuser.ini that mentions the last five people to dictate at the PC under that windows profile name, but like I say this only keeps the last 5. In the user's roaming profile on the network the list of PCs a person has dictated at is kept in USERNAME\USERNAME\current\audio.ini. If you're having trouble with people and PC locations being 'remembered' by Dragon check first here that the list of PCs is growing and appending as people dictate at multiple workstations
If you want a user to be able to dictate at more than 9 PCs without their profile forgetting which ones they've been at before, you'll have to look at the nssystem.ini file under documents and settings, all users, app data, nuance, natuarally speaking 10. In the .ini you need to add a line under the [Settings] header that reads exactly:
Number of Audio Settings=300
In our environment we're only starting to look at getting dictation going through pooled VDI desktops so I can offer any more advice that this. Hopefully if anyone out there has gotten this working they can offer some details.
