Windows 2000 Pagefile

I am running Windows 2000 Pro with the service pack 1 on my system. After restarting my system after installing several of the updates from Microsofts Update page, I am now being told by the computer that either the pagefile does not exist or is too small. I follow the instructions given to me by Windows to either increase the size of the pagefile or type in a size for the min. size of the page file to create a new page file. Neither of these options have worked. I would appreciate any advice anyone could give.

Thanks
