local part = script.Parent

local endPart = workspace.End

while true do
	task.wait()
	
	local startPos = part.Position
	local endPos = endPart.Position
	
	local lookAtCF = CFrame.lookAt(startPos, endPos)
	
	part.CFrame = lookAtCF
end

where is the script?

#3 
local part = script.Parent

local endPart = workspace.End

while true do
	task.wait()
	
	local startPos = part.Position
	local endPos = endPart.Position
	
	local lookAtCF = CFrame.lookAt(startPos, endPos)
	
	part.CFrame = lookAtCF
end
#4

part.CFrame = lookAtCF * CFrame.Angles(0, math.pi/2, 0)

For a 90 degree anticlockwise rotation around the Y-axis.
