Difference between PING and TRACERT

[lamaar]

Can someone explain why if I ping one of my servers I get 'Unknown Host', yet I can TRACERT to it?

eg.

I cannot do this: PING *SERVER*, I get
UNKNOWN HOST

but can do this : TRACERT *SERVER*, I get

tracing route to SERVER.UK.COM


Thanks

It does not happen with all servers. Lamaar75@hotmail.com

Are you using WINS or DNS for your name resoluation? Todd VanDerwerken, CCNA, CCDA

Thanks for the reply.

We use DNS to resolve names.

And this happens everytime for this 1 server, right?

One thought I had was if you had a primary and secondary DNS server that maybe when you did your request it was doing a round robin things where request 1 went to server 1 and request 2 went to server 2 and request 3 went to server 1, etc..

But you would think that at sometime your ping request would go to the same server as your tracert.

Sorry I couldn't be any more help Todd VanDerwerken, CCNA, CCDA

What if you try using the fully qualified domain name? IP address?

ie ping server.uk.edu
ping 123.456.789.123

if using NT/2K try
nslookup server

do you have anything in your local hosts table?
