Hi,
I didn't have any problems with password in using ActivePerl.
At the first time you login to DSS3.x, login name and passwd are
"streamingadmin" and "default". What do you mean by "RIGHT PASSWORD"?
If you are sure that you were able to change login password, why don't you
try typing the latest password as well as any previous ones?
You don't have to use .exe stuff to change password. WebAdmin works fine to
me.
