Topic: Connection problems

[mrmango]

Hi,

I have currently upgraded my SME from 7.0 to 7.1

This was a clean install wiping all previous data (test server).

However I seem to be stuck with a machine I cannot connect to. The network is setup with 10.0.0.x style ip range. A router sits on the highest range giving DHCP returns and acts as the gateway. The SME sits as a server only. I have setup the server as 10.0.0.100 IP address. All other machines are DHCP desktop/laptops in a lower range.

I have setup a user on a test laptop, with the same on the SME. However I cannot get the laptop to see the SME server other than a server under the neighbourhood, then it will not authenticate the user.

I am stuck as far as I know everything is the same.

Lastly, the DNS server on the router has the hostname stored as the correct IP address. I can nslookup the hostname from the laptop and it returns the IP. I cannot connect via SAMBA, WWW as admin or ssh. All of which are switched on and allow local connections.

Any ideas?

Thanks

Dave

Can you ping the laptop and the router from the server?

Can you ping the server and the router from the laptop?

Does the internet test work on the server?

If the answer to any of these is NO, then you have an IP addressing problem, otherwise it is most likley samba authentication problems,  so, then check that the server and the laptop has the same workgroup name, and that the username (and password) is the same on both the server and the laptop (no funny characters in the username/password?).

Is the laptop XP/Home or Pro?  Home is not so good at logging in automatically to the samba network.  Also check that the Wins server setting on the laptop is set to the server.

It is much better (i.e. easier) to use the DHCP in the server and turn off the DHCP on the router.  Try it even if you intend to switch back for real.

Thanks for the response.

The server cannot ping the laptop, the server can ping the router and use it.

I cannot ping the server from the laptop, however I can ping the router from the server.

The internet test does work.

Additionally there is no firewall on the laptop.

The OS is XP home, however it did connect before to the server, before I upgraded.

I tried DHCP on the server and it failed to give a DHCP response.

Have you set the workgroup settings via server-manager?

You may have had the same workgroup for both machines previously.

[mrmango]

Yes,

Both named the same.

Would help if I paste IPconfig from both:

Laptop

IP Address: 10.0.0.1
Subnet: 255.255.255.0
Gateway: 10.0.0.138

Workgroup: solar

Server

10.0.0.100/255.255.255.0
Gateway: 10.0.0.138
Addtional local networks (of which seems standard I cannot remove): 10.0.0.0/255.255.255.0
DHCP disabled
Workgroup: solar

Hope this helps.

Additionally there is no firewall on the laptop.

This is another obvious possible area of trouble - check control panel/windows firewall.  If you have just "disabled" (eg) Norton, then you might find it still interfering.  You must uninstall it.

[mrmango]

Windows firewall disabled and the no other product installed.

It is as if they exist on different networks.

Also for the Samba using it is using upper case and lower case with a none alphanumeric. However SME prefer those types.

[brianr]

I dont think you answered whether you can ping the router from the laptop?  Can it surf the internet?

Are you sure the server is in "server only" mode?

[mrmango]

Apologies if I hadn't. Yes the laptop can ping the router.

Yes the server is in server mode, only one ethernet card within the machine.

[mrmango]

Are there any logs I can check to see if anything failed on the SME Server?

[mrmango]

Added a new laptop to the network, it can see the server!

So I now have to believe either SME is blocking my other laptop or the laptop cannot see ip 10.0.0.100.

Strange one.

Any suggestions?

[brianr]

I think it is more likely to be something wrong with the config of the laptop - does it have SP2 on it?

Unless the laptop IP address "10.0.0.1" is considered special by the server.  Try changing the laptop IP address to 10.0.0.2

[mrmango]

I have tried a few TCP IP stack repairing tools, also looked in the arp cache and it sees the IP / MAC but I cannot route to it.

Other than wiping the laptop cannot see how it is not seeing that IP.

Strange.

[mrmango]

Ok sorted.

I looked at the SME ARP cache and found it could see IP but no MAC address. Therefore I removed the network card from the hardware profile and then reinstalled. I also downloaded and ran Windows XP SP2 HotFix Q88402.

Whether it was the hardware and the hotfix I do not know. I do know however once the hardware was reinstalled it was perfect and could see the SME server.

Thanks so much to all who replied to this!!

Thanks
