Hi Rajat,

Check that your LAN router interface has the same network mask as the Win8 PCs network card.

Also that the IP address that doesn't work is included in router interface access-groups if configured. Likewise if there is any NAT on your network that the Win8 PC IP is included in the NAT source ACLs.

cheers,

Seb.

Have you confirmed that there is not a duplicate IP on the subnet?

[r.kukreja]

yes. i am suspecting issue due to virus but not confirmed. how can i confirm, is there any possible solution

Does the problem affect any PC trying to use this IP address, or does it only affect this one Win8 PC?

If you move all PCs off this IP address, ssh onto the subnets router and run:

clear arp-cache <affected_ip_address>

sh ip arp <affected_ip_address>

Does it return a result?
