you need give us more info:
* What are you using as DNS server ? (maybe you have a DNS problem not a network problem)
* Do you try to ping an IP address (internet and LAN)? What do you got?
* What mode have you choosen (server, private server, server&gateway)?
* How many NIC do you have on server?
* What IP and netmask of your computers AND of your gateway?
* Do you disable DHCP server on SME ?
* What you put on netmask on server config ?
* What version of Windows do you run on computers ?  Are they firewall disabled ? What about AV?

Do you read the manual on Wiki pages ?

1. there is no DNS srver . as the network is basically for interset sharing. and all DNS is through ISP server through ADSL modem.
2. yes i trie to ping to the server from outside and othr way round. what i a getting is "destination host unreachable"
3.i have chosen server.
4.i have 2 NIC. tried ineterchanging them also.
5.ip of my network is 192.168.1.2 to 192.168.1.32 .. netmask is 255.255.255.0. gateway is at 192.168.1.1
6. yes i have disabled the DHCP of SME.
7. i have put 255.255.255.0
8.i have windows Xp and their firewall are disabled. but i had tried from  a linux box as well. also i tried to ping the gateway as it is a Modem with no firewall but no reply is comming.

yes i ahve read the manual but may have missed something.. plz point out my mistake..

If you are running the sme server in server only mode, I think you should remove the network adapter no 2, as this might mess it up a bit.

[chhatrashal]

can i disable it without removing it.

To shutdown eth0:
ifdown eth0

To enable eth0:
ifup eth0

OK... BUT even if you´re using ISP DNS, you must have one configurated on computers or will have no name resolution.
Choose one WinxP computer and run: "ipconfig /all" and post here.

2. yes i trie to ping to the server from outside and othr way round. what i a getting is "destination host unreachable"

Normally it´s one of 2 things: bad IP config or not internet at all.
Please do a "ping 200.176.2.10" and a "ping 192.168.1.1" from same WinXP computer as above and post here.

3.i have chosen server.

Are you sure you do not choose PRIVATE server option?

4.i have 2 NIC. tried ineterchanging them also.

Disable 2nd NIC on BIOS or remove it and post results of "ifconfig" on server here.

5.ip of my network is 192.168.1.2 to 192.168.1.32 .. netmask is 255.255.255.0. gateway is at 192.168.1.1
6. yes i have disabled the DHCP of SME.
7. i have put 255.255.255.0

Those appears be fine.

8.i have windows Xp and their firewall are disabled. but i had tried from  a linux box as well. also i tried to ping the gateway as it is a Modem with no firewall but no reply is comming.

that is a huge problem... you should be able to ping your modem/default gateway because this is a LAN!
I suggest you to try to connect your modem to a single computer (a notebook maybe) and try to ping it an web.

yes i ahve read the manual but may have missed something.. plz point out my mistake..

I´m trying. If you like, you can contact me at my gmail (just type using gtalk!) account: jader.marasca  so we can diagnose it quickly.
But I´m pretty sure your problem is to be unable to ping your default gateway (ADSL modem)...as this would be possible from ANY computer from LAN!

To be on the safe side I would first have removed the extra card physically, and then logged on to console as admin to run a config setup. The server should then work.
