A technically precise reading of the description on the item does not indicate that non-protective spells are not removed.

A familiarity with the functionality of Dispel Magic in DDO also suggests that it will remove all kinds of spells; and knowledge of monster stats indicates that their defensive buffs will only rarely be the ones that get removed.
