Everything works perfect on my home computers. At work I'm behind an ISA server. I've got problems using boinc through this ISA. By browsing the help-group I found a solltion, though it requires me to leave my logon name/password in a textfile. Because I'm the administrator, this is not what I want.
Even if the proxy-settings from Boinc would work with ISA I would have the same problem; Boinc stores these in a XML document. Would be nice if Boinc would work using encrypted passwords, or NT credentials you us to login to windows.
