What is the Reporting Server / SRS reports URL?

When using Microsoft Reporting services, 2 url’s are important:

1. The url of the report manager website (By default http://[DatabaseServerName]/Reports )
2. The url of the report server(By default http://[DatabaseServerName]/ReportServer )

[DatabaseServerName] is not necessarily the domain name of the server. 

If you have multiple database instances on your server, the naming schema is a little bit more complex.

So a quick reminder to myself, for a server with multiple database instances:

1. The url of the report manager website becomes http://[DatabaseServerName]/Reports$[InstanceName]
2. The url of the report server becomes http://[DatabaseServerName]/ReportServer$[InstanceName]
