Catalyzes CTP-mediated phosphorylation of dolichol, the terminal step in de novo dolichyl monophosphate (Dol-P) biosynthesis. Dol-P is a lipid carrier essential for the synthesis of N-linked and O-linked oligosaccharides and for GPI anchors. CTP + di-trans,poly-cis-dolichol = a dolichyl phosphate + CDP + H(+) Belongs to the polyprenol kinase family.
