Slow proxy speed new nt install 2.5

["Wayne Gaybba" <wgaybba@xxxxxxxxxxxxxx>]

Hi, Just installed nt ver 2.5, it is very slow at client's but fast at 
server. Cache log is filled with
idnsRead: FD 5 recvfrom: (10054) WSAECONNRESET, Connection reset by peer

I can't see any other errors in any of the logs.

What do I do now?

Thanks
Wayne
