Windows updates causing loss of network connectivity

It has been posted that Windows updates KB4480970 and KB4480960 are causing network issues on some PCs.  This loss of network connectivity is causing Sage BusinessWorks client workstations to suddenly stop working.  Some of the symptoms that Sage BusinessWorks users may experience include:

  • Error: "The item that this shortcut refers to has been changed or moved, so this shortcut will no longer work properly." when launching Sage BusinessWorks
  • Cannot access Sage BusinessWorks on a client
  • Lost all shortcuts to the server
  • Mapped drive icons disappeared
  • Error: "The mapped network drive could not be created because the following error has occurred: The handle is invalid." when trying to map to a drive

At this time the only known resolution is to roll back the Windows updates causing the error.

Once the update has been removed it may be necessary to install the Sage BusinessWorks client again.  For more information on this issue see KnowledgeBase article 95234
