Im trying to net use \\(remoter machine's ip\sharename.
but when I try to do this I get network locatin cannot be reached. I can ping the machine perfectly fine. Its not behind any sort of firewall.
Its running on one of my networks. I have netbios enabled on my internet connection. I'm running windows xp by the way. Turned on all services I believe is needed to make this connection. Any info would greatly be appreciated.
Thank You

Hi TerenceC,
Do you know for certain that the traget machine can/have been reached from a remote host?

Even though your remote machine is not behind a firewall, it will still need to have a route through the router for the necessary port(s), and the fact that ping goes through is not a certain indicator either.

Do you know what the seup at the remote site is:

 - which router ?
 - do they use NAT ?


Kind regards,
Sven

theres is no nat and its sitting behind a router with a public IP address, so technically anyone could get to it if they wanted too.
And its a cisco 2500.

TerenceC,

My best bet will still be the router, - is it possible for you to get the config at post it here ?

I already installed vnc on a test machine on that network. and have no problem accessing at. We have pc anywhere also on machines no problem.
We even use remote desktop on some.  I was  leaning towards a improperly set up xp pro machine mainly mine lol. Because I'm trying to get in thru net use which i believe uses netbios.

TerenceC,

As you try to connect using IP-addr, rather than netbios name, I cannot come up with any cause why your XP box should not be able to map a net-share.

Furthermore, the reply is: "Network location cannot be reached".

Do you have another box at your location you can test share against ?

Also remember that TCP/IP filetring may be configured on the server box at the other end.


Regards,
Sven

Many ISP's have gone to blocking TCp ports 135 and UDP ports 137/138 - all the Netbios ports required to make your drive mapping.
Are you perchance on a broadband cable or DSl connection?
Who is the ISP for the other end with the Cisco router?
Is the router allowing netbios across?
Have you tried with a LMHOSTS file on your PC with an entry for the remote PC?
I find it hard to believe that you have several systems "bare naked" with public IP address, no firewall, and no filtering or NAT on the router...
