mapped drive id & pwd

["Jim Franz" <franz400@xxxxxxxxxxxx>]

Is there a place to maintain the user id & pwd of a mapped drive?
I have a mapped drive, which was checked to reconnect at login.
Now pwd has changed, but can find no place to edit the pwd.

iSeries Nav file > File Systems > File shares
right click & has options to open, explore, map drive, and properties
(but properties only has minimal properties)
If I select Map Drive and and remap the same drive - even though I use 
new pwd, next time I log in, it does not reconnect.
Also see no option to delete mapped drive definition so I can start over.
System at V5R4
iSeries Nav at V5R3 (and will take to V5R4 today)
