Hi!
One solution is to configure the DHCP-server and/or the DNS server to update
the
DNS record for the laptop when it acquires an address. You might want to
consider using rather short TTL in the DNS in order to minimize the risk of
using outdated IP-addresses due to caching.
Another solution is to make WINS name resolution work over the subnets. But
someone else has to fill in some info about that.
Good luck!
