Pls see attached diagram. This is the setup.
From the PC Vlan (vlan 200) able to ping other server on Vlan 300 except this server 172.19.100.101 & 172.19.100.102.
I don't know why can't ping this 2 server. I suspect because of this firewall but i don't about the configuration.
Please help me to verify

It seems there's no problem on your switch, As you are using Router-on-Stick for inter-vlan routing, problem might have occurred on 2811 router (as shinepothen said).
it helps if i can see your 2811 Isetan configuration.
Something else; You have not full connectivity with servers or just ping does not work?
I checked both of your switch and router. All of your ACLs, trunks and sub-interfaces look fine or at least i could not find faulty point.
Consider that running debug on ACLs and couple of show commands will be helpful.
Check firewall rules on your servers,
keep informing us.
That what i thought also..config of router and switch just fine.
The server firewall is fine also, as other server from 172.19.100.x able to ping and connect to the 172.19.100.101 & 102.
That why i suspect the firewall config might have to do with it....but im not really sure if it is correct or not
Really i couldn't figured out why i can't ping this specific IP address.
Is there any configuration at the router that prevent it?
check if you have some thing in the server which is blocking the things.
try to turn off your anti virus
turn off any proxy setting if you have any
turn off windows firewall
check all possibility from the server end to see if any thing is blocking.
hi, it would not be the (antivirus, proxy, windows firewall) because from VLAN 300 (PC, Server) able to ping to this specific host.
Only that from VLAN 200 it can't be ping though.
it just a staging server, normal..
Thanks providing the information.
now what I can suggest is
try to remove the current IP address from the server and try assigning a different IP from the same subnet.
put the servers IP address to some other machine or test machine and see if the communication is still working or not.
because we see the configuration is correct and them what is that stopping the communication from this host.
i can try that..but it is live environment server, i'll need to find time for downtime...
if it is not the router, not the switch, it could be the PIX that prevent the ping
