XP... okay. Something to have a look at:
Start | Settings | Control Panel | Network Connections | Local Area Connection | Properties | Internet Protocol (TCP/IP) | Properties
I assume that's set to "Obtain an IP Address Automatically" and "Obtain DNS server address automatically"?
Also, I assume there's a tick next to "Internet Protocol (TCP/IP)" in the long chain of stuff above?
So, here's a possible test, if the above is as I hope it is and your network is fairly predictable:
Change the settings to "Use the following IP address" and put in:
- IP address: 192.168.1.12
- Subnet mask: 255.255.255.0
- Default gateway: 192.168.1.1
Then set "Use the following DNS server addresses" and configure:
- Preferred DNS server: 208.67.222.222
- Alternate DNS server: 208.67.220.220
Then OK all that and reboot. The reboot shouldn't be required but I'd do it anyway in this case.
Then try the following four tests from the command prompt (Start | Run... | cmd) ...
Also, please report on:
Let us know how that looks.
