"The network dataset has already been built" message

Discussion created by ilya.s.solovyev on Dec 17, 2012
I have two GDBs (1 and 2), both have replicated dataset with one polyline feature class.
Dataset in GDB-2 has network dataset, where polyline FC-2 is a source.
See figure in attachement: [ATTACH=CONFIG]19993[/ATTACH]

I make some changes in polyline FC-1, replicate changes to GDB-2. OK, polyline FC-2 is changed. But network dataset has no changes. When I try to rebuild network, ArcCatalog says "The network dataset has already been built".

I use ArcGIS Desktop 10.0 SP4 at GDB-1 and 10.1 SP1 at GDB-2. Working with GDB-2 from GDB-1 server (with Desktop 10.0).
Any ideas?
