iNotes is not working

I have installed the Lotus server 6, and found that i am not able to use the iNotes as well as webmail. When I enter the url like 192.168.18/mail/pc.nsf it ask for the username and password but after that it gives error and not allow to access mails.

Please help me.

Thanks in advance

Under the person document and miscellaneous tab type INOTES in the Comments field. Try logging in again. Don’t don’t ask me why, but we do this for all new iNotes users.
