actually we have 2 servers one for development an another is the production / live one
there are several QVWs that either connect to database and create QVDs or simply read the generated QVDs
whenever we make an update on any of the QVW files, and copy the QVW from Development server to the production one the task that is created on this document will fail and the error says: failed to open document. Document might require username and password.
Re: Why would a QVW ask for user name and password ?
IMHO this sounds more like a problem with the development account copying a QVW to a system where the QVS service account cannot access the document (NTFS). If no section access is used at all, that is.
