Have networked 3 xp computers together using a router, They can all share the broadband connection simultaneously so I am happy that the router is working. Machine 1 ( brand new ) can see the other 2 machines ,but cannot access them ( Get aan access denied message).
machine 2 (12 month old) can see machine 1,but not machine 3.can access machine 1
machine 3 ( !2 month old laptop) can see machine 1, responds to a ping, access denied message if you try to access 1, cannot see 2
All computers are on the same workgroup ( MSHOME) and addresses have been allocated by DCHP through the router ( iE 192.168.8.x)sub 255.255.255.0
Zone alarm has been instructed to accept the range of ip addresses from the network
Are there any security protocols that i have overlooked
