WINS is disabled as is DHCP. The DNS was root but I have deleted the root zone to enable forwarding of DNS to my ISP (Could this be the problem here? - although it works). This server is the only machine running DNS on the network.
I have a single DLink DI624+ router/switch to which clients are connected, one wirelessly.
Until recently I have had no problems. However, I have just build an XP Pro client machine (192.168.1.150) and connected it to the domain. It is configured with a static IP address and has a hosts table (not lmhosts). The DNS on this machine is set to the PDC (192.168.1.100).
After some time in use the XP client simply refuses to access any network resources (Printers or shares) but is able to ping any client on the network and ping the server. Internet Access also works although this is via the ethernet modem (DLink DSL300T) rather than the server.
If I reboot the server access is resumed as normal for a period of time.
This error only occurs on the Windows XP machine, the 2000 clients operate correctly.
Can anyone shed some light on the situation?
Thanks.
