Hi

Have a strange problem.
On my network i am trying to rdp onto two of my servers.
i can connect to them fine from all other machines using similar credentials.
But on one  client machine it cannot connect, neither will it ping these two specific servers.

where it gets strange is that this client machine itself can ping and rdp fine onto all other servers.
when it tries to ping these servers it resolves the correct ip but cannot get a reply by name or ip.

all servers are win 2008
all clients are win 7

Sounds like its using IP V6 and server is on V4, or vice versa.  Also, verify DNS and do an ipconfig /dnsflush

dns seems to be fine, all names etc. resolve ok.
have flushed cache anyways

have disabled ipv6 on both but still seem to be getting same error.

Check the subnet mask on the PC.

Have you checked your firewall and gateway settings?

Are all the machine in the same LAN/SUBnet.

Check the routing table on the clients, whether they have a route to the servers and also on the servers whether they have route back to the clients.

Could you to a tracert x.x.x.x to the server and see where it stops?
