How are you trying to configure, If its through Active Directory make sure that you have Use Active Directory , Enable Automatic login if desired.

Thanks

Tableau Server requires a "Run As User" account to be able to access services especially for a distributed environment.

For a standalone Tableau Server installation you could leave the default value it populates with and continue with the installation. 

At the very end of the installation, it will then prompt you to setup an administrator account. 

As a doublecheck, in the \bin directory of Tableau Server you might want to run the 'tabadmin status -v' command just to make sure all services are up and running including the Gateway service.

If that looks good, next would be to verify what port was selected for the Gateway service.  By default it will try to select port 80 and in that case it shouldn't be necessary to add the port number to the URL when you try to access Tableau Server.  The configuration tab should reveal if it had to select another port (eg 8000).  In the latter case you would need to specify the port (eg http://localhsot:8000).

If nothing is down and you're using the correct port, you can try running the 'tabadmin reset' account to be prompted to setup a user account.

Satish,

When you went to the URL http://servername:80 is it showing you a login screen but you just can't login?  Or is the screen completely blank?   That is you don't see any fields to enter in a login or password.

Since you issued the one tabadmin command.  Could you try to go to the same URL in the browser again?  On that screen is where there will four fields instead of two that should allow to setup an account.

Could you reply if that worked?

Satish,

Glad to hear you got it working!
