can’t access vendor’s ftp site from server 2003 r2

I need to access a vendor’s ftp site to download some software – but can’t from my new windows 2003 R2 server using IE7. However, I can however access this site from other servers in my domain that run Windows Server 2003. I believe I have narrowed it down to something in 2003 R2 but not for sure. I know that I could download files from one server and move it to new server but vendor says that won’t work for what they need to do. Any ideas?

Thanks,

scott
