If you're asking the question and you haven't run in months, then I assume this is not a no-brainer for you, probably because you are older or bigger (ask me how I know).
To get this done in the few weeks that you have, I'd get on an actual track and begin with run/walk. Start out at the necessary 2-minutes per lap pace that you need for each lap to hit the standard. Do one lap at pace, then slow to a quick walk for a half-lap, then run again, then walk and repeat until you've done two miles. Adjust as required, but with the idea of, on a daily basis, lengthening the run periods and shortening walk periods until you're doing the whole two miles at pace.
The advantage is that you can measure very precisely your progress towards the goal. Lots of ways to do it, but if I only have a few weeks, then I want to be able to see and measure progress every day, which this method will do.
