We're currently evaluating Reporting Services 2005 vs. Cognos ReportNet.

One issue that's coming up are the software requirements for general users to use the Report Builder feature.

Cognos is a zero-client install product. RS 2005, on the other hand, requires the following of users:
+ .Net Framework 2.0
+ Report Builder installation
+ Report Model updates

This causes a problem at our organization because most of the business users' machines are locked down, meaning they don't have administrator access. They do not have the rights to install model updates, or any other software, without special requests.

If anyone could help me understand the reasoning behind these installs, I would appreciate it.

Thanks,
Mike
