I found 1 reference to this file in a newsgroup posting. The solution, though, was posted in German, but it talked about the "CCC CLient" and a Service for it that ran.
Now, I don't know what the "CCC Client" is, but at least that is something. Basically, boot into Safe Mode, find the Service for this application, and set the Service to Disable.
Then boot normally, and hopefully Win2K will come up and stay up. You can then see if this application (CCC Client) is needed, and if so, look for a patch or fix it, etc.
To read the discussion thread, and see the answer in German, go here:
