[Discuss] yast stop working

[J.Bakshi]

Dear list,

here is a critical problem. I have added a http source to the yast and after 
that every time yast reports an additional source using the yast database so 
it can't start the package installation process. even it reports the same 
after restarting 
the machine. So I like to delete the source I have added into yast. 
could any one kindly suggest the location of yast configuration file where it
stores the sources ?

I have already check /etc/YaST /var/lib/YaST but have not found the file
I am looking for. 

thanks
