May be this..not sure...but an Idea..take away publishing rights from Admin for the moment and add some user who has got Publishing Rights and whose ID should only be known to you to Publish Workbooks.
Hi Dale, you can do this with the Help menu:
Help Menu > Settings and Performance > Clear Saved Server Sign-ins
Thanks, Deepak and Jeff
Actually, we don't know, who has this admin id OR Not. We have a large number of users. We were thinking If we change the password of the admin account. They nobody will be able to publish the workbooks from tableau desktop. But that is not happening.
We can not go to each other computer and log out from there OR create the account for every user. When we do not know the list of users.
