NWDS Error when Re - Loging on to the Development Configuration

Hi All,

I am new to the NWDI and NWDS stuff. Following is the error description.

I am able to ping the SLD server successfully.

I am able to create a new Development Configuration by putting the credentials also.

The Problem is when i try to re-login to the already created Development Configuration i get this error

"User/Password Invalid or Expired". but using the same password i am able to log in and create the development configuration but when I log off and try to log in again at that time it throws the above error.

Request you experts to help me resolve this error.

Thanks in Advance,

Sanjeev Sharma
