Bug: A "table was not found. [GDB_Networks]" error is raised while using INetworkWorkspace.OpenNetwork and INetworkWorkspace.GetNetworkNames methods
While using the INetworkWorkspace.OpenNetwork and INetworkWorkspace.GetNetworkNames methods a "table was not found. [GDB_Networks]" error is raised when attempting to open either a geometric network or a standalone logical network.
The ability to directly open logical networks has been removed starting at the ArcGIS 10.0 release of the geodatabase.
If opening a logical network, use the IGeometricNetwork.Network method. If opening a geometric network, use any number of the methods on the INetworkCollection interface.
