Change information on login page

Hi,

The login window to enter the username & password of development server shows Welcome to ECC 5 SR 1 Development server SP--stack 13

Client 100 : Customizing/Devlopment Client

Client 300 : Unit Test Client

Also, as it gives textbox to enter the username & password, I am able to login but problem is with SP-stack13 because just now we update the system upto SP stack 16.

I want to know how can I change this settings on logon page?Please suggest.

Regards,

Rajesh
