prompted for sage login when previewing invoices

We recently migrated our local server installation of Sage 300 CRE to another server.  (Sage V. 20.5.1)

Since then, all users are prompted to login to a DB whenever they preview an invoice in Service Mgt.

Sage support has not been able to resolve this.  My Assistant works with the same reports, so that leads us to think the reports are fine.  

Any ideas are greatly appreciated!!
