we have 3 servers. all servers and client computers are on 1 domain.
one client computer has had the following issue on two occasions:
computer loses contact with one server only. this computer is unable to ping the server by name, and pinging by IP yeilds the error "Destination host unreachable". computer is able to ping other computers in the network, and the other two servers, and computer can access the internet.
reboot resolved the problem on both occasions, but i want to know why it happened, or what troubleshooting steps i can take next time in order to help determine why it is happening.
computer in question is xp pro with all service packs and updates. firewall is disabled.
server in question is windows 2000 server. it hosts an SQL database that is used by an application which is run from client computers in the domain.
