Hi, Do you have UAC switched on? If so, please start your browser with elevated privilages. I hope it helps. J.There are 10 type of people. Those who understand binary and those who do not.

I am logged in to windows as administrator. on browsing to http://localhost/reports I get the login window asking for the login details. I even enter the admin login but the login window remains. Any thoughts please? Thanks

What is UAC and how can it be switched on pls? Thanks

Sounds like may already be on. http://technet.microsoft.com/en-us/library/cc709691(WS.10).aspx Try right-click IE icon and Run as administrator Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

I am logged in as admin.

May not matter. Unlike earlier versions of Windows, when an administrator logs on to a computer running Windows 7 or Windows Vista, the user’s full administrator access token is split into two access tokens: a full administrator access token and a standard user access token. During the logon process, authorization and access control components that identify an administrator are removed, resulting in a standard user access token. The standard user access token is then used to start the desktop, the Explorer.exe process. Because all applications inherit their access control data from the initial launch of the desktop, they all run as a standard user. Regards, Dave Patrick ....

Hi, As Dave mentioned, you need to start your browser with elevated privileges - Run as administrator. If you still have issues please take a look on my article at here. This week, I got dozens of times the same error at different customers. I hope it helps. J.There are 10 type of people. Those who understand binary and those who do not.

I log in using admin account. Still not sure what to do? Thanks

Right-click IE desktop icon and choose Run as administrator Regards, Dave Patrick .... Microsoft Certified Professional Microsoft MVP [Windows]

Hi arkiboys, In your case, we can try to disable RSWindowsNegotiate authentication and then enable RSWindowsNTLM authentication in the rsreportserver.config file.
