Hello, I had a problem with the server reporting sevices (locally) I can not connect to it, I suspected a dll file in System32, because when I tried to uninstall and install SQL Server to solve the problem it gives me an error that says: access is denied to this file (when uninstalling and installing), I tried several solutions but I have not managed to solve the problem. After I formatted the PC because it started to take me a long time, and also to have no problem with dll files. After formatting, I installed SQL Server, everything went fine, but when I try to connect to the server reporting services, I can not, and I get an error that says: Unable to connect to MA-CASA-D1229. It is possible that the URL specified is not valid or there is a problem at the server version or configuration of reports. Enter another URL or contact your server administrator to verify that the report server running SQL Server 2008 or later. Although all SQL Server services are started, the name of srveur is correct, I even tried localhost and it did not work, I tried all modes of authentication, none of them works. And knowing that I can log in normally the engine database, the Analysis Services server, and Integration services server. And thank you in advance.

Hi phenomeno1923, From your information, it seems that your URL registration failed. Actually, URL registration errors are logged to the application event log file. For instructions on how to view the log file, see Windows Application Log. If you encounter an erroneous URL reservation error that prevents you from using the default URL, you can use the Advanced Multiple Web Site Configuration dialog box in the Reporting Services Configuration tool to clear the URL so that you can re-use the defaults. Start the Reporting Services Configuration tool and connect to the report server. On the Web Service URL page, choose a non-default value for the IP address (for example, 127.0.0.0). Click Apply. Restart the service. You can use the Stop and Start buttons on the Report Server Status page in the Reporting Services Configuration tool. Reopen the Web Service URL page. Click Advanced. Click Add. In IP Address, click All Assigned. Select port 80. Click OK. On the Web Service URL page, click Apply. In the URLs list on the Web Service URL page, click the URL to verify it is valid. Delete the URL that you created in the first step if you do not want to use it. Click Advanced to select and then remove the URL.
