Try this command to allow icmp traffic to these networks:

access-list acl_in extended permit icmp any any

Then apply the access list to the inside interface:

access-group acl_in extended in interface inside

The access group command must match the name of the access list

pablouruguayAuthor Commented:
mmm i resolv the problem add manually a persistant route in the host

try a route print on one of the xp workstations to check the routing table for this network that cannot be pinged
Are there any firewalls on the xp machines blocking icmp ?
then you need to look in your routers to find out why the default gateway of these xp workstation cannot reach this network

what happens with a traceroute query?
pablouruguayAuthor Commented:
like i post in the post below,    i need to pix do a persistant route in the host is that possible?
You can do that, but you need to really look at the routing tables. Can servers in this subnet ping these hosts? Does the dhcp scope have the correct default gateway?  Are you using dynamic routing protocols such as eigrp or ospf so the routing tables can see all networks?
pablouruguayAuthor Commented:
i dont use dynamic routing, is a simple network with 2 gateways ... 1 internet, 1 intranet

all traffic 10.x.x.x goes to my router all the other traffic goes to internet

but in the hosts i cant ping my servers internally 10.x.x.x trough my router. but pix can ping all my intranet. i only need the pix give a persistant route to the hsots.
If you have checked your routing tables and a route exists for these hosts to the servers, then something (firewall) is blocking icmp on these machines. If the firewall allows for icmp traffic, then pings should work. If they are win xp machines, then  try opening icmp traffic throught the firewall using the netsh command
