Might be the network card in the server.

When you can't ping the server, go to it and see if you can ping out....or at least ping the adsl modem. If you can ping the adsl modem or an XP machine on the network then it's not the NIC in the server. From an XP machine when you can't ping the server, can you ping the adsl modem? Is the modem hot when you have to reset it? Can you ping from one XP machine to another XP machine?

From an XP machine when you can't ping the server, can you ping the adsl modem?
Yes ADSL modem replied.

Is the modem hot when you have to reset it?
Yes, and ADSL modem is power on daily 8 to 9 hrs.

Can you ping from one XP machine to another XP machine?
No, I can't.

Since you can't ping from one XP machine to another, that tells me it's a hardware device on the network like a switch or the ADSL modem itself.

Since the modem is hot when you have to reset it, I suggest first trying a fan pointed at the modem so it'll keep it cooler and see how that works.

Maybe your switches and modem are all in the same place and one fan can blow across all network hardware and prevent future outages.
