Hi Garry,

Are you able to obtain any more information from your client?

For example, what exactly is the error message they receive? It sounds from your post that they receive it when trying to log in to Adagio?

Is this a new installation or did this behavior just start happening? If so, what has changed? Do they have any LanPaks?

Also, you say they are using VISTA. What kind of server are the using? Are they running peer-to-peer? What versions/dates of Adagio OE and IC are they running?

Sorry for all of the questions but we really do need more information to try to troubleshoot this for you.
