Changing back to Windows authentication Mode Problem

[sanan]

Hi Every Body
I just fixed my Problem of not being able to connect to my SQL server.
But at first I was using the Windows Authentication Mode,Then I changed to SQL and Then back to Windows, Which the Problem “Not being able to Connect” aroused.
Now my Question is how can I Change it back to Windows Mode?
I tried the Right Clicking the Sever and>Edit Server Registration>choosing the >Windows But no Success, Could it be because that in SQL Server Mode I deleted some of the users including the Guest and Admin “I think”?

Best Regards
Sanan

In Enterprise Manager, right click on the instance name, select Properties, click on the Security tab. That's where you make the change.
