The Repair Connectivity command fails with the following message: "Inconsistency with the network elements".
There is an issue with one of the logical network tables that prevents the Repair Connectivity command from succeeding.
This issue has been fixed in ArcGIS for Desktop 10.1.
There are two workarounds for this issue. The first is to drop and recreate the geometric network. The second is to run the Rebuild Network command on the geometric network. This should only be performed when working with Technical Support. Please contact Support to work on this issue.
