Toshiba Satalite Pro A300-1EA Wired LAN Issue
A strange problem with the above laptop which is running windows XP Pro SP3 which im hoping you guys can help me out with.
The laptop is connected to our network via CAT5 and manges to get an IP address lease from our DHCP server without any issues. If I ping any hosts on the network in the office locally this works fine without any issues. The problem I have is that we have several offices which are connected to the same network which are all on the same subnet but unfortunately I can't ping or communicate with these nodes.
Likewise if I was to connect the laptop to the network in one of the remote offices I can ping\communicate with any other nodes locally but nothing on the other side of the switch\router (in the main office or any other remote sites).
This issue is only this laptop as other laptops seem to work fine without any issues.
The drivers for the NIC which is a "Realtek PCIe GBE Family Controller" are all up to date and I have tried using several versions of the driver which don't seem to resolve the issue.
My initial thought was an issue with the Cisco switch and router that was sat in-between the laptop and our head office and our remote office which one of our Cisco network guys has taken a look at and cant find any issues. Other things that have come to mind are either hardware issues or group policy which Im currently investigating.
Any other suggestion or ideas would be Welcomed!
