Fix 401 error while accessing sql server reporting service with c# code

While working with reporting service in our last project we had to face 401 issue while accessing reporting service from remote computer(using .net code).After lot of digging in the net i found the following solution which worked for me on both windows server 2003 and server 2008.

1. Click Start, click Run, type regedit, and then click OK.
2. In Registry Editor, locate and then click the following registry key:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. Right-click Lsa, point to New, and then click DWORD Value.
4. Type DisableLoopbackCheck, and then press ENTER.
5. Right-click DisableLoopbackCheck, and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Quit Registry Editor, and then restart your computer.
