How to implement a distributed reporting topology for Operations Manager 2007

This article by Gordon McKenna details the steps for configuring a distributed reporting environment (one in which the SQL databases and SRS server are located on different computers) in OpsMgr 2007. The least understood part of a distributed reporting topology is configuration of the identity needed to access the SRS databases on the remote server. As Gordon points out, this can be accomplished by using the OpsMgr Data Reader / Data Writer account to eliminate the need for yet another domain identity.
