Having trouble connecting to Report Manager

You have to give this user the rights to run Report Manager.

First, start Internet Explorer with elevated privilege, using Run as Administrator on the SQL server.
 
Open http://localhost/reports   (you may have to login with your Computer's username and password)

You should now be directed to the Home page of SQL Server Reporting Services here: http://localhost/Reports/Pages/Folder.aspx

From the Home page, click the Properties tab, then click New Role Assignment

In the Group or user name textbox, add 'JuanVelasquez\Juan Velasquez'

Check all the checkboxes; Browser, Content Manager, My Reports, Publisher, Report Builder, and then click OK..

You should be good now.

I tried and received the following error message
Object not found!

The requested URL was not found on this server. The link on the referring page seems to be wrong or outdated. Please inform the author of that page about the error.

If you think this is a server error, please contact the webmaster.

Error 404

Make sure you have access configured to the URL http://localhost/reports using the SQL Reporting Services Configuration.

To do this:

Open Reporting Services Configuration Manager
Connect to the report server instance
Click on Report Manager URL
In the Report Manager URL page, click the Advanced button
In the Multiple Identities for Report Manager, click Add.
In the Add a Report Manager HTTP URL popup box, select Host Header and type in: localhost
Click OK to save your changes.

Hello Michael,

I've done as you suggested and I still get the same error message

I have sql server 2008 and 2012 installed on my machine along with report services for 2008 and 2012.  I'm going to uninstall 2008 and its associated reporting services, in the event that reporting services 2012 is getting confused.

I'm still not having any luck

<somewhat sarcastic>  Who's the DBA that set up this server?  I recommend a gentle tap with a sledgehammer, or whatever impliment of motivation you think would be effective, for this person to grant you access, as it's usually not available without specifically granting it, and the DBA at my current gig is about as open and transparent as a brick so he won't tell me.

Good luck.

Excellent!  This is the best way to learn.

I was able to figure out the solution myself
