Problem with sessions.

I am using sessions for holding who is logged in and it is kind of working. I have got a few emails from customers saying they cant log in (and seeing as we have had less than 30 orders this is a real problem). I can log in OK and cant recreate this problem. Any ideas regarding what this could be would be much appreciated. I guess if you have cookies turned of it wont work but what else may cause a problem.
