doubled smoked ham how long will it keep?

Genevieved

Can anyone tell me how long it will keep in the fridge? 

At my dad's job we lives at his work site in a trailer when he is working.  He works two week on one week off.  So ppl in the area will often drop off food they made for him and someone dropped off a large doubled smoked ham for him (the person smoked it themselves) .  He didn't know what to do with it and it was just him so he knew he wouldn't be able to eat it on his own.  He gave it to us but it has been in his fridge for a few weeks (I don't get to see him often)  Also he couldn't take it home because he works in the US and lives in Canada.

So is it ok to eat?  What is the best way to cook it?
