967673  (http://support.microsoft.com/kb/967673/ ) Description of the Communicator 2007 R2 hotfix rollup package: April 2009
This update addresses the following issues:
  • When this update is installed, Communications Server 2007 uses NTLM authentication when Communications Server 2007 returns SEC_E_TARGET_UNKNOWN in the 401 response.
  • The Add Contact Wizard in the File menu has a search option that does not work in the Services environment. When this update is installed, the Search option in the wizard is skipped. The user can still use Search from the main UI search area. The Search functionality in the main UI search area occurs in an inband provisioning change.
  • No error reports are sent when you fail to subscribe to the presence of others. When this update is installed, Communicator 2007 R2 reports subscription failures when the following registry subkey is set.
    \HKEY_CURRENT_USER\Software\Microsoft\UCCPlatform\Communicator\ReportPubSubFailure
    • If the ReportPubSubFailure subkey is set to 0 or if the subkey is not present, an error report is not sent.
    • If the ReportPubSubFailure subkey is set to a value that is greater than 0, an error report is sent.
  • When the update is not installed, Presence Change Toast for Tagged Contact does not have an "Untag" link when the TelephonyMode is set to 5 in the registry. This update resolves this issue and provides the "Untag" link.
  • When the update is not installed, the "TelephonyMode = 5" setting (for IM and Presence only) functionality is controlled by using a by using a Group Policy setting. When this update is installed, this policy setting is also available through inband provisioning. The policy setting will continue to be supported and will override the inband provisioning.
  • When the update is not installed, the DisableFileTransfer functionality is available only through a policy setting in Communicator 2007 R2. When this update is installed, the DisableFileTransfer setting is also available through inband provisioning and will override the inband setting.
  • Communicator 2007 R2 sends a registration update request (sip REGISTER) every 90 seconds when Communicator 2007 R2 is connected through an HTTP Proxy. This type of connection increases the load on the Communications Server 2007 Front End server. When this update is installed, Communicator 2007 R2 sends a "white-space keep alive" request every 90 seconds and sends the REGISTER update request only at the negotiated time.
