Thanks susie

Problem is solved now. Virtual Machine was not part of the same affinity group thats why problem occur.

Thanks & regards

Hi,

Based on my research, all virtual machines that you create in Windows Azure can automatically communicate using a private network channel with other virtual machines in the same cloud service or virtual network.

Since you disabled firewall on the VMs, can you ping the IP addresses of the VMs between each other?

thanks susie for reply,

but i tried to ping and telnet to one of open port but no luck and i disabled both firewall and SELNIUX

ping 10.157.28.5
PING 10.157.28.5 (10.157.28.5) 56(84) bytes of data.
From 10.157.28.4 icmp_seq=2 Destination Host Unreachable

telnet 10.157.28.5 16001
Trying 10.157.28.5...
telnet: connect to address 10.157.28.5: No route to host

i also tried tcpdump to port 16001

sudo tcpdump port 16001

Hi,

Did you use TCP port 16001 for the endport? It seems that telnet commands can only used for TCP connections. In addition, it is hard to say which is the reason for this, maybe you can using Network Monitor to capture packets between the VMs to find the root reason.
