Re: revisiting the vanishing user (in Windows)

Hi,

I made the changes in the required files by checking the cvs repository on the web. But now, I have a problem while starting the server.
This is what I see (on the server side):
..the usual stuff ..

I am working on Windows 2000 using ozone-0.6.1.

I don't understand why it is printing shutdown in the first place and of course have no idea about this error. 
Any help would be greatly appreciated - thanks!

I had to rewrite the entire server but it seems that I managed to fix this ;)
It's in CVS. Please check this.
