I have a question regarding SSRS 2005 and MOSS 2007. I want to pass parameter for report using URL. I have come across lot of information related to it

This post suggest a solution:

www.beyeblogs.com/.../passing_paramet.php

It says instead of using following link:

https://www.myMOSSServer.com/.../07

Using this: https://www.myRSServer.com/ReportServer?https://www.myMOSSServer.com/.../07

Solves the problem.

When I tried it, I got an error :

The type Microsoft.SharePoint.Portal.Analytics.UI.ReportViewerMessages, Microsoft.SharePoint.Portal, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c does not implement IReportViewerMessages or could not be found
I used this link to take care of error:

insomniacgeek.com/.../

 This nasty error message appeared when I published my Reporting Services local report to a custom Web Part.

"I solved this be comment out the ReportViewerMessages line in appSettings section in the web.config

<appSettings>
<!--  <add key="ReportViewerMessages" value="Microsoft.SharePoint.Portal.Analytics...... /> --> 

So far, I haven't seen any issues by commenting out this entry. "

Now, I can see the report but only when using Admin login. When I use a less-privileged account, I get an error :

The permissions granted to user 'ServerName\UserName' are insufficient for performing this operation. (rsAccessDenied)

As I understand It is to say to access report, person needs to have access to report server. Has any body encountered same problem?
