Mainframe issue

Question

Hi All,

 My application is developed in visual basic 6. Our application is use to connect with Mainframe server using RUMBA. To connect with Mainframe systems we had mainframe system id and password. By using these credentials we use to connect with 3 Mainframe systems(WFADO EAST,WFADOCENRAL and WFADO WEST)

 

Earlier we are able to connect WFADO EAST, and remaining two were not connect.

 

Now 3 Systems we are not able to connect by using credentials.

 

For those three systems userid is same but password is different.

 

What would be the problem?

 

Please share your ideas to get it resolve.

 

Thanks
