hey i dont know anything about a DoS attack but a server is having some problems. its a new server running win 2k, 2.4 gig intel xeon, 1 gig DDRAM. not even a month old. the problem is that interoffice email is taking 18 hours and office ping is around 4000! all workstations are new. there are 14 computers on the network. at first i thought about the NIC cards, (10/100) then maybe i thought they could be using a hub, not a switch, then i thought about cat-5, but i just cant figure out why its so slow! the workstations are running novell small business (im pretty sure) ive tried to include all information that would help you guys out, if you need to know anything you can IM me at smth op 86 or email me at [email protected] thanks a lot for any help!
