Hi, I have a document Library under a site and I am trying to Break permissions inheritance. I receive the following error: "Operation aborted (Exception from HRESULT: 0x80004004 (E_ABORT)) at Microsoft.SharePoint.Library.SPRequestInternalClass.ResetSecurityScope(String bstrUrl, UInt32 dwObjectType, String bstrObjUrl, Guid guidDoc, Boolean bUnique, Boolean bCopyRoleAssignments, Guid& pguidScopeId, Int32& piError) at Microsoft.SharePoint.Library.SPRequest.ResetSecurityScope(String bstrUrl, UInt32 dwObjectType, String bstrObjUrl, Guid guidDoc, Boolean bUnique, Boolean bCopyRoleAssignments, Guid& pguidScopeId, Int32& piError)" This only happens to the specific Document Library. Any ideas ? Dimitris Porikos
