I'm trying to run the Generate From/To Node for Lines against a water network. I've been able to run other ArcHydro tools against this data without issue (e.g., Set Flow Direction, Store Flow Direction, Assign Hydro ID). However, every time I try to run Generate tool, I receive the error shown at the end of this post. Not sure if the path to the C drive is a clue? It doesn't exist on my PC.

After the tool throws the error, I can see that the FROM_NODE and TO_NODES fields have only been updated for 5000 of the 50434 features. Anyone have any suggestions?

I'm using ArcGIS 10 desktop (Info license), SP1.
