I found this event log
Logon as a local administrator.

2. Stop the "SQL Server" service and run "C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Binn\sqlservr.exe" -m" (as described in http://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=353451 to start SQL Server in Local Only mode.

3. Logon to SSMS from the server itself - no password required.

4. Add your own domain account as a Login, with sysadm server role.

5. Restart the SQL Server service

Hey -BEFORE you try the ABOVE :::

Do this:
Verify that the windows user logged in and accessing SQL Server has the necessary permissions in SQL SERVER by going to the security tab and checking if the windows user is already setup.

windows users will appear in this format : domain\username

Deepak ChauhanSQL Server DBACommented:
It is seem like port error Please try to connect to sql server with port name

eg: servername\instancename, 1433

if you are using windows group user like domainname\username then sql server will  connect in windows authentication model
not in sql authentication mode

If you are using sql server user then it will be connect in sql authentication model

and another thing please check port in sql sever configuration and endpoint also
