The Topo2Raster Tool allows you to create a DEM from vector features, and as a byproduct, also allows you to create a stream polyline feature.

But I already have a DEM, how can I create stream polyline features from it?

Agnar,

You need Spatial Analyst.  Here is a good starting point.

An overview of the Hydrology toolset
