[Abhishek Aggarwal]

Hi All,
I am facing an issue in my organization. The issue is when i am trying to ping to windows 2003 standard 64 bit server i am getting the following response.
 
64 bytes from 172.17.0.19: icmp_seq=1 ttl=128 time=2.05 ms
64 bytes from 172.17.0.19: icmp_seq=2 ttl=128 time=0.229 ms

but when i am trying to ping any flavour of linux i am getting the following response
64 bytes from 172.17.0.11: icmp_seq=1 ttl=64 time=0.086 ms
64 bytes from 172.17.0.11: icmp_seq=2 ttl=64 time=0.075 ms

I had checked by conecting the windows and linux servers through cross over cables and also the windows servers have also been formatted but still no conclusion is there 
 sysctl -p is
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 4294967295
kernel.shmall = 268435456
net.ipv4.tcp_keepalive_time = 10
net.ipv4.tcp_keepalive_intvl = 10
net.ipv4.tcp_keepalive_probes = 2

 
This issue is creating a lots of problem in my working need your help
 
Thanks and Regards
