cannot access postgresql 7.3 via pgadmin III

["Amit Sharma" <amit(dot)sharma(at)wificom(dot)com>]

Hi,

I am trying to access postgresql version 7.3 using pgadmin III from windows
2000 OS but i always keep getting the error Fatal - password authentication
failed for user root. i have allowed access in the pg_hba.conf file for all
users to access all databases by the defined ip's but still whenever i try
to access the database from pgadmin remotely i get the error Fatal -
password authentication failed for user root. I have also a set tcp ip =
true in postgresql.conf. Can you please give me some hints as to what could
be the problem.

Thanks
regards,
Amit
