Dogs can hold it all night because urine production slows down at night, don't use the same schedule during the day as you would at night. Do you keep her in a kennel all day and expect her to hold it? This is not going to work. I really feel badly for the dog, because they hate too poop and pee in their kennel and have to be in dire need and pain before they will do it. Most people who leave for the day, put the dog in an x-pen with a pee pad, and allow them to relieve themselves when necessary. You can build up to 8 hours a day in a kennel, but that's not much of a life for a dog. It sounds like you need to figure out exactly what you want and how much time you want to invest in reading about training techniques. Basically you have taught her that the kennel is where she must relieve herself. To reteach her you will have to do several things such as cleaning the kennel thoroughly, with a special enzyme cleaner, making the kennel small enough so that there is only room enough to stand up turn around. The most important step is to take her out of the kennel every couple of hours and place her in the spot where you want her to poop and pee. Then she would be allowed free time, where you watch her closely, and then back in the kennel. This usually trains them in a week. It sounds like you are expecting too much if she is to wait all day. At this age she could probably hold it 4 hours, but she hasn't been trained to do that yet. I think this is a great site, and it has step by step methods.
