Setting up a P2P WIFI link

Hi All.
Because I do not live far from school (about 150 Mts. LOS) I'm setting up a WIFI link from school to home to run the network etc. (I hope with maybe some help from you guy's)
I plan to use two USB WIFI adaptors and two old satellite dishes at a total cost of about £35.
With one dish with one USB adaptor at the focal point mounted on my house, I have done some tests to pick the signal up at school by just holding the other adaptor in my hand and pointing it at my house ( That looked ok and will be better when I put up the other dish).

Now to the test set up at home .

I have two old computers linked with a good WIFI signal .
They are set up P2P.
I can ping each way on the fixed IP numbers (not dhcp) .
call it computer 1 . I can look in a test shared folder on computer 2 from 1.. no problem, add to it etc.
but from computer 2 to one I get 'There are no logon servers to service the logon request' I have both computers with the same name and passwords and with administrators setting.
Any idea's please.

Michael.

Let me just get back into my chair ...


Obvious to check: is the computer that doesn't respond XP SP2 or does have any form of software firewall

Is the server service also running?

Two computers w2k adv. server. with all updates.
Zone alarm firewall with the ip add. set up. on both.
Note they have two NIC's in each computer.

Re. Is the server service also running? .....do not understand.?
Michael

The question about the firewall is because the firewall has to have an exception for file sharing either for the specific IP of the computer acting as the client.

The server service is background process which implements file sharing on the computer hosting the share.

If you're using the WIFI link for remote admin, I hope the link is encryted.

Thanks for your help .
Both computers are set up the same.
so why can I access the shared folder one way and not the other ?. Disabled the firewall for this test .. still no good and I get the same message up.
Re.. "If you're using the WIFI link for remote admin, I hope the link is encrypted". yes It is.

Are you sharing using the computer names or their IP addresses?

Hi.
I still need help I'm stuck.!.
The folders on each computer are shared with full security for everyone.
on computer 2 . I can look at the internet via the wifi link ok .

As I said earlier these computers are part of my test set up and have RRA,DNS,IIS,Indexing Service set up on them both. and are set up as the same domain.
domain server ip 192.168.0.10 sm 255.255.255.0 dg 192.168.0.10 dns 192.168.0.10
-------------------------------------------------------------------------------------------------------

smoothwall box ip 192.168.0.1 sm 255.255.255.0
------------------------------------------------------------------------------------------------------

computer 1 with usb wifi adaptor ip 192.168.100.1 sm 255.255.255.0 dg 192.168.100.2 dns 192.168.100.1

second lan card (nic) ip 192.168.0.11 sm 255.255.255.0 dg 192.168.0.1 dns 192.168.0.10

---------------------------------------------------------------------------------------------------------------------------

computer 2 with usb wifi adaptor ip 192.168.100.2 sm 255.255.255.0 dg 192.168.100.1 dns 192.168.100.2

second lan card (nic) ip 192.168.1.1 sm 255.255.255.0 dg 192.168.0.10 dns 192.168.0.10 nothing pluged in this at the moment

On properties of the USB network adapter :-
client for ms networks
load balance
file and printer sharing
AEGIS protocol
network monitor driver
TCP/IP....
All ticked.

DNS problem - have you set it up on either?

There is an ancient thread hereabouts where someone used a directional antenna - a bit further away I seem to recall.

Check threads on security too - WPA at least I think is the recommendation.

As it's P2P either use the IP addresses directly or add the names in the HOSTS file of ech machine.

Can you ping the machine names [quick check if DNS working]

What about we get together now on chat somewhere as we're all here together guys?

Your wifi adaptors on different IP range to the domain server and smoothwall box Mike? With a mask of 255.255.255.0 surely that shouldn't work?

Hi.
RE.. "DNS problem - have you set it up on either?" you may be right, on computer 2 dns is running but on computer 1 its NOT set up.!
Do you think that's the problem ?.
Do the above ip addresses etc. look ok I'm not very good at setting them up .?.
Have looked at some of the old threads.

I will look into the security of the wifi link at another time. "land of nod time soon" it was 4am last night so got to make an effort to night !!!.

Should only have 1 DNS server set up Mike - didn't see your setup post 'till after I posted that.

The subnet mask should be 255.255.0.0 if your 3rd octet is going to be different.

DNS is by far the most likely cause yes.

Hi. computer 1 and 2 are set up as routers with NAT and DHCP relay agent . to hopefully separate school network and my home network.
computer 1 ping name for 2 ...failed ... it thinks the other NIC 192.168.1.1 is what it should be talking to ?.
computer 2 ping name for 1 that's ok

Michael ...ps What's 'chat' not used that.

It looks like both computer 1 and 2 are using their own WiFi IPs are their DNS and default gateway.

As the IPs are statically set they will not be known to the DNS server whether is is on the DC or the SmoothWall box.

Either use the IP address UNC

e.g. NET USE \\192.168.100.1\ShareName$

or put entry

Code:

---

192.168.100.2                Computer1

---

in the HOSTS file of the Computer2 i.e.

C:\WINNT\System32\drivers\ETC\HOSTS
