I received this error message during model deployment:
The report server installation is not initialized. (rsReportServerNotActivated) (rsRPCError)
To fix, I launched "Reporting Services Configuration Manager"
On the Initialization (which did have a green check mark) page, I noticed two IDs, one had a check and the other did not. After attempting several scenarios, I had to actually delete both Instance IDs and then click the Initialize button to create a new instance.
After that, all was well in Reporting Services 2005 land.
THANK YOU!!!
Why is it always the obvious one... :(
