network slow downsLocked
I am running a windows 2000 server and a linux debian server with a adsl connection for internet access. There are 5 windows XP machines on the network 6 windows NT4 PC and 4 windows 98 PC’s and 3 windows ME pc’s. all machines plug into two piggybacked 100meg netgear switches. The network has been running fine for about 1 year. About 2 months ago users on the network started complaining about the network slowing down for about a half hour to an hour on some days, ie it takes 3 mins to save a autocad file to the server when it should take seconds. the server is not running DHCP or WINS all PC’s are staticly IPed. Does any one have any suggestions to why this may be occuring?
Thanks in advance
