Restart Message in PI

Hello,

We want to restart the message in adapter Engine from the rwb.

When we trying to restart the message, it is asking the username and password.

the problem is the password filed is not accepting the whole characters. ( i.e: the password field is accepting only 10 chars, where as password is actually more than 10 character.)

How can we resolve this issue

We are using SAP Pi 7.0

Regards

Ashish
