NOTE: If you attempt to create a new dial-up connection, some of the options are dimmed.

If you upgraded from SP3 and you had NOT previously configured the Routing and Remote Access service, or a remote access dial-up connection, some of the remote access-related binary files are immediately replaced. When the service pack Setup programs installs support for the 802.1x and initializes these new binaries, they conflict with the old binaries that had never been initialized.

To workaround this issue, shutdown and restart your computer to bring the remote access binary files up to date.
