I created a blank site in Sharepoint 2010 and in
Site Actions-->Permissions I removed all the users and added an Active directory group which has me as member and few others.
After this I logged in as myself and it does not show that Portal on Left navigation. If I try to browse to that portal as myself it says "access denied"? I don't know where I am wrong. I am stuck from yesterday. If some one could help it would be great. Thanks.
