Hi Hitendra,

What is the error? Post a stack trace. Describe the behavior that you
believe is errant.

Note that Windows 2000 is no longer supported by Microsoft so
technically I don't either. But it has been known to work in the past.
At least with the latest SP it does.

I don't know but I doubt it. I would need to see symptoms beyond
"suddenly it stop working" to perform any kind of real diagnosis.
