request timeout

I have computer A and B and Other devices.
Computer A can ping Computer B and Other devices without any problem.
Computer B can sometimes ping Computer A and sometimes Cann't, but always can ping other devices.
I mean when i enter this command at Computer B
Computer B>>Ping A -t

Have you tried a tracert to see where its getting hung up?

> tracert A

Do you have any firewall that may be blocking the pings intermittently?

Have you checked all cables are o.k. change them around, see if the behavior follows the cable.

NIC card fully operational? Have you tried with another one, that is known to be working fine?

192.168.0.1 is usually a router's IP address. How are your IPs assigned in your LAN, DHCP or hard-coded?

all cables are changed and the NIc card is not changed , because it can work with other devices , so if it is the NIC card problem it shouldn't work with any other devices, is that right?
