Win2k Corrupt Config File, Help Please

[Silkk28]

I went to startup my computer today and it said that I have a corrupt config file and will not boot. Is there any way to fix this problem without formating the hard drive? I just installed service pack 2 a couple days ago and suspect that as being the cause. Any help would be greatly appreciated.
