Major issues that are resolved by this update
Issue 2The installation of the client connector is blocked when you turn on Gatekeeper and enable installation from the AppStore or trusted developers on a computer that is running Mac OS X 10.8 Mountain Lion.
Issue 3When the Apple Bonjour service is running on a Windows Small Business Server 2011 Essentials-based server, client computers cannot connect to the server by using the client connector.
Issue 4When a security identifier (SID) is empty in a computer configuration file in Windows Small Business Server 2011 Essentials, the client backup database corrupts and the client backup service fails.
Issue 5When you run the Remote Web Access Setup Wizard to configure a Windows Live domain, an error occurs. Additionally, you may also be blocked when you try to remotely browse a Remote Web Access (RWA) page. This issue occurs because the Windows Live ID Sign-In Assistant component is unexpectedly uninstalled.
Issue 6Assume that you set up a remotely administered server from a client computer. You set the time zone to Pacific Standard Time (US & Canada) in the Time Zone Settings dialog box. In this situation, the time zone is incorrectly set to Baja California on the server after you finish the server deployment.
Issue 7When the XML convert module handles invalid files in Windows Small Business Server 2011 Essentials, you receive error messages that state some services cannot be started.
Issue 8This update fixes the Server Backup service exception issue that occurs when the backup service tries to retrieve backup history from event logs. For more information about the Server Backup service exception issue, go to the following Microsoft website:
Issue 1You cannot install this update by using a Mac client connector that has Update Rollup 4 for Windows Small Business Server 2011 Essentials installed. This issue occurs because of a change requirement for Mac external binaries. To work around this issue, reinstall the Mac client connector before you install Update Rollup 4.
Note This issue only occurs on a server that has Update Rollup 3 for Windows Small Business Server 2011 Essentials installed.
