Workflow Validation Error

hi,

If I try to validate Dynamics Ax 2009 workflow web service from Ax, I receive the below error.

“The request failed with HTTP status 404: Not Found.”

I changed Enable 32 bit property as TRUE in IIS 6 Application pool.

Its not working again.

Anything I ve to check in IIS 6?

I again reinstalled the workflow … stil showing the same error while validating
