The system drive in a client's SBS2003 machine failed. I replaced the drive, and restored the data and system state from backup.
The server is running fine, except that network clients can no longer connect to it!
The server has network connectivity - it can ping all other network hosts and access the internet over the LAN.
The clients (all Windows XP) do not get any response from the server - not even DHCP or ICMP. If I set a client to a static IP in the correct subnet, the server can ping the client, but the client can't ping the server.
There is no firewall installed on the server. It does have AVG 7.5 Anti-Malware SBS Edition, which was installed 2 months ago.
- rebooted the server, clients, network switch and router
- uninstalled the network card driver and updated to the latest version
- replaced the network card entirely
- replaced the network cable
- run 'netsh int ip reset'
I am now out of ideas! Any guidance greatly appreciated.
