Children Services Back Today in Jackson Case

TMZ has learned the L.A. County Department of Children and Family Services will be coming back to the Jackson family home in Encino to interview the children ... and deal with a little Internet problem going on inside the house.

Sources tell us DCFS spent 6 1/2 hours yesterday speaking with adult family members as well as staff.

We're told many -- but not all -- of the people social workers spoke with are giving the same account as Katherine Jackson (through her lawyer, Adam Streisand).

Sources tell us one of the issues DCFS wants to deal with today is making sure there are controls on the access children in the house have to the Internet.

As we first reported, Jermaine Jackson's 13-year-old son, Jaafar, purchased a stun gun online -- and that's what triggered the DCFS investigation.
