Issue
Vista reports fail to save to the server when they are being edited from a remote workstation.
Product Line
TAC Vista
Environment
- Vista
- Microsoft Excel
Cause
When setting up remote workstations on a LAN or WAN, there are certain steps that must be taken. If the proper DCOM settings are not set up on every remote workstation as well as the computer that runs Vista server, there can be authority issues. Vista reports can be created but will not allow values or trends to be saved into the report. In some cases this has generated the error "The RPC Server is unavailable" as seen in Error: The RPC server is unavailable.
Resolution
On ALL remote workstations and the main server:
- Run DCOM Config 1.0.2.2.exe found in Helpful Vista Utilities - Configure DCOM instantly, Register ASP.NET. Either select Server-Workstation or Server-Workstation-Webstation.
