AIX Non Expired Password

Hi,
I am into production support and handling some of the AIX servers. We are planning to have a user id on a AIX system with non-expired password. Now the question is that if I have a non expired password then I cannot do a interactive login to AIX machine ( i:e cannot do Telnet ,SSH etc) from Windows . How will I do the non-interactive login from Windows to AIX with a user id having non-expired password?.

Pls help on this!!

Thx,
Sid
