OK on the TCPIP section I changed it manually to the following settings

IP Address 192.168.0.57
Subnet Mask 255.255.255.0
Default Gateway (blank)

Preferred DNS Server 192.168.0.1
Alternate DNS Server (blank)

Still doesn't work

The annoying thing is that on the host I can go to Start > Run and type in \\192.168.0.57 and up pops the other computers accessible folders

If I try and do the same with \\192.168.0.1 from the client, nothing, hangs for ages then says it can't be found.

So they're definitely talking to each other it just seems to be a one way conversation.....
