I have a workstation with win xp in an office network from which I can not ping to any other machine on the network and the ping from any other machine to this workstation also fails. for both the netbios name and ip address the result is the same. But I can browse the network and network shares from the pc and can also browse the internet. Could any body help me to solve this issue.
thanks very much.

hi,
this could a matter of an active firewall. you might be using an installed firewall or windows built-in one. the built-in you can adjust at connection properties, you can click the advanced tab and uncheck the firewall option. or, if it is installed firewall, then disable it or uninstall..

for more details, see the processes running in background and cancel any that could lock the network.

Regards.

what are the ip addresses for both comptures. it is importatnt that ip address matches with the address mask on both computers. ie, if Mask is 255.255.255.0, then the ip address should be within the range of xxx.xxx.xxx.0-254, or if the mask is 255.255.0.0 then the range is xxx.xxx.0-255.0-255 ; For each box the ip must be different, of course.

an example configuration for tcp/ip protocol:
 box1:
IP address: 192.168.0.17
Mask: 255.255.255.0
box2:
IP address: 192.168.0.29
Mask: 255.255.255.0

I found that the subnet mask is correct because they are all set to get automatically from the dhcp

ip for the pc :       10.70.118.10
              subnet: 255.255.255.0

and others in same range.

I have now formated the pc and resolved the problem. Any way, could there be any other reason except the ones you have mentioned. If yes pl give other possibile reasons so that in the future if a similar problem is there, i can do some thing.

thanks a lot. I will accept your comments as a  possible answer.

regards

ashm1,

there might be several reasons like viruses or other proccessing running in background, incorrectly configured advanced tcp/ip settings.

surely fromatting the pc is a solutions but there are some other solutions:
1) under device manager you can do uninstall and re-install for your network interface card (and think of updating network driver by downloading drivers from manufactures website). before doing this, remember to save all important setting for connection (ip, mask, dns server, domain name,computer name, etc)
2) check the computer for viruses using latest virsus database

regards.
dzelde.
