SSRS Report Deployment Connection Error

A co-worker received the following error message when attempting to deploy a report from Visual Studio to a Sharepoint document library setup for Integrated Mode with SSRS.

“A connection could not be made to the report server…”

The message was followed by some additional information that indicated “Client found response content type of ‘text/html; charset=utf-8′, but expected ‘text/xml’.” as well as some additional HTML tags.  The error dialog was rather ugly.  Other developers working on the same solution with other reports were not having this problem.

The gist of the problem was that the developer’s PC did not have SQL Server 2005 Service Pack 2 installed.  Once the Service Pack was installed the error went away and the report could be deployed.
