Apache Mongrel Proxying problem


I have a small rails application I need to deploy in our corporate
I am using a Windows Vista (i dont have any other option on this part)
to host the application. I am using InstantRails and the rails
application is running on port 3000. When I try to use Apache to proxy
mongrel I get the following error message.

Unknown error: proxy connect to x.x.x.x port 3001 failed

I have disabled the windows firewall

The application is working fine if access mongrel directly and apache is
also working.

Any help is appreciated!
