Unable to access server on LAN

[shailendra harinkhede]

We have strange issue that we are unable to access the one server 10.10.3.236 

Its in our LAN, and the same server we can access from remote VPN (GP & CISCO anycoonect, citrix).

User (172.x.x.x/24) ---Catalyst SW(L2)---COR Nexus  SW ( L3 Gateway for all network)---Server (10.10.3.236 )=== Not working 

Users on remote VPN (172.30.223.0/24)---FW ----COR SW (Gateway for all network)---Server (10.10.3.236 )=== working fine.

Any suggestion or solution will appreciated!

Can you ping any other host in the same subnet as 10.10.3.236?

If you trace 10.10.3.236 from 172.x.x.x subnet, where does the trace stops?

I can ping the server 10.10.3.236 from 172.x.x.x subnet,  its not an issue. 

When I access on "\\pfsarc2-prod  (10.10.3.236 )" its not working from 172.x.x.x subnet,.

Make sure its DNS name entry is correct.

does nslookup "pfsarc2-prod" return IP 10.10.3.236?

Well, from this point you can ping 10.10.3.236.

1. What protocol that you use to access the server ? If I see the way you access, you are going to open shared folder? correct me if I'm wrong
2. Can you just use ip address to access the server ?
3. Is there any access-list on nexus ?
4. Is there any blocking rules on server iptables (if the machine is linux based) ?
