Hey everyone,

I connected a machine to a gigabit switch.  It can ping the router (which is connected to the switch but it cannot ping any other machine on the subnet.  It does, however, respond to ping.

What could cause this?

i've tried resetting the tcp stack.

Windows 7 x64
Broadcom Netlink onboard NIC
DGS-1008 Switch
Watchguard 25-W router
DLink DGS-108

Looks like this:

Watchguard Port 0 -> Tompson DSL Modem
Watchguard Port 1 -> DLink DGS-108

Computers and printer connect to DGS-108

192.168.2.1 (router)
192.168.2.18 (computer 1)
192.168.2.19 (computer 2)
192.168.2.26 (printer)

.18 can ping .19 and everything else and route to the internet
.19 can ping .1 but nothing else, no internet..

Help?

Have you verified your TCP/IP settings on .19?  Specifically, ensuring the subnet mask matches the mask of the other devices.  What about the default route on .19?  Is it configured to forward packets to 192.168.2.1 (gateway) via the 192.168.2.19 interface?

Network Destination        Netmask          Gateway           Interface
          0.0.0.0                      0.0.0.0              192.168.2.1    192.168.2.19

You may want to temporarily disable any host firewalls while you're troubleshooting.

Check your IP/subnet as well as the routes on .19
ipconfig /all
route print

You can always do a tracert 192.168.2.18 it may tell you what the problem is.

Also check DNS setting, suffixes, gateway address, turn off firewall (if it is on), temporarily disable any anti virus you may have.

like Coffinated said. run a Route Print and IPconfig /all on .18 and .19 and post results.

Removed AV on both.. internet works on .18, not on .19 but now i can ping between .18 and .19 both ways after AV and firewall was turned off.

Last thing seems to be routing to the internet from .19

Alright so here's what happened:

There was a crossover cable in the system that the client had installed without my knowning.

Also, WatchGuard devices won't route traffic for more than one PC until they have been activated.

Lesson learned.
