Unable to editing user profiles

Question

I've SharePoint Server 2007 installed on Windows Server 2003 (x32). I'm trying to create Alerts but I get the error:

The following users do not have e-mail addresses specified: System Account, pc-Name\user1, pc-Name\user2. Alerts have been created successfully but these users will not receive e-mail notifications until valid e-mail addresses have been provided

I am not able to even edit user profile information.

Answer 1

I found it. Actually I've enabled shared services provider on server so I'm not able to edit the profiles from People and Groups page from Site Collection pages. You need to go to Shared Services Provider site and from there to People and Groups to edit user profile.
