Change the name of the system, as it might be used in the network. In the default gateway of the XP machine, give the server IP which is connected on the network. Reboot the XP machine.

Ping the local system with the server, to check the connectivity. Try to connect it to the network.

These are on different subnets so it could be down to firewall rules/policies. Or it could be down to a missing dns entry for Try pinging with the fqdn and then pinging another pc on the 23 subnet.

Sounds like a DNS problem. More info would be needed to troubleshoot effectively.
Does your W2003 Server act as a DNS server?
If so can you ping the pc by name from the server?
Do the PC's use the server for DNS?

  • Yes,I can ping by name. – Sam Apr 23 '12 at 10:58

If you can ping sebastian then DNS works. Some parts of Windows like net use \\sebastian (and presumably Explorer too) resolve names not via DNS but WINS a.k.a NetBios Names.

Perhaps a misconfigured WINS is the source of your problem. Do you have the same problem with other clients on the network?

It can be the wrong date or time.

I Just had this problem. Please check the date and time. It won´t allow you to access the server if the date/time is different of the client machine.
