Hi and thanks for your reply.

If I change the NIC card details to 255.255.255.0, increase the range as
suggested (think i'll have to delete the existing DHCP scope to do this),
will I still be able to see all the other devices on the network with the
subnet of 255.255.255.128 as per my previous post, we can't change the router
details because the other network needs to be left alone.

One thing i messd with is creating a superscope that includes a scope
ranging from 172.24.53.10 to 126 and another scope from 129 to 250. But
anything that gets an IP from the "secondary scope", 129 or above, ca't ping
the server or see shared resources. If I release the IP and make it get one
from the 10 to 126 range, I can ping and see shared resources.

Thanks.
