RAPD Problems - Control lanes with bands

I've been performing RAPD reactions using primers from the UBC lab
and have been running a control with the same stock as my tests (Primer,
taq, buffer, dNTPs, H20) replacing the DNA with sterilized water, yet I am
consistently getting banding patterns in these lanes WITHOUT DNA... I have
replaced the H20, dNTPs, taq and buffer and yet the bands are as strong as
ever! Is this a common setup for a control lane?
These banding patterns differ from reaction to reaction and from primer
to primer, yet bands appear in control lanes even when some of the test
lanes are clean... Has anyone had any similar experiences and/or any
suggestions as to where in the protocol this error might be introduced??
Any help would be greatly appreciated.
