Overview
——–
Newly built network. No connectivity between my 2003 SP2 server and XP Home SP2 workstations on the LAN.
Further details
—————
1) Workgroup network.
2) Ping requests between the XP machines and the 2003 server fail with “request timed out” to hostnames and IP addresses.
3) Ping requests between the XP machines are successful to hostnames and IP addresses.
4) The browse list in the workgroup is not being populated. i.e. on the 2003 server, when I select Workgroup” in network neighborhood, only itself is listed.
5) Web browsing is successful from all machines via the ADSL router.
6) My ISPs DNS server IP addresses have been configured on the router.
7) The router is serving as a DHCP server and is successfully dishing out IP addresses from 192.168.1.33 upwards.
8) NAT is enabled on the router.
9) For testing purposes, firewalls have been completely disabled on the router, the 2003 server and the XP machines to no avail.
My technical knowledge is OK, but not great. This one has baffled me for a while now!
Any help greatly appreciated!
