Users receive a security alert when they try to connect to a secure Web site on the computer running Windows Small Business Server 2003.

Platí pro: Windows SBS 2003

Cause:  This commonly appears after using the Configure E-mail and Internet Connection Wizard to create an unsigned certificate for the company Web sites. Because the certificate was issued by Windows Small Business Server rather than by a trusted certification authority, the server itself is not being authenticated as the server that you want to connect to.


  • The session is still encrypted, so it is not possible for others to view information that you are sending. Users can click Yes to accept the unsigned certificate. If your company requires a higher level of security, consider purchasing a signed certificate from a trusted certification authority.

  • If the Web site is being accessed from a private computer from which the site will be accessed repeatedly in the future, users can click View certificate to install the certificate into the certificate store of the client computer.


For security reasons, users should not install the certificate if they are accessing the secure Web site from a public computer, such as an Internet kiosk.
