Newforma has noted some recent issues with Riverbed of which we wanted to make this forum aware.  There is a new CIFS (Common Internet File System) overlapping files optimization in Riverbed 5.0 that results in access-denied errors when two Newforma apps, Newforma Project Center Server and/or Newforma Project Center (client), try to access the same project from different offices. 

The specific user experience is slowdowns in the UI.  After the client gives up, an error message is frequently displayed around being unable to open a file such as “b2cfd59e-fd66-102b-8d99-4ac5fca23626.npm”.

Disabling this optimization allows all applications to continue working properly.  The attached image provides guidance on exactly where the “Overlapping Open Optimization” is managed.
