HELP ASAP!! Nothing on LAN sees sbs server, Server can access WAN only.

Here is the setup. Multi site with sonicwall tunnels connected to one site with SBS server.

Server is connected with single nic, cannot see anything on lan segment. Cant ping router, clients etc. Can however connect to the wan. Clients cannot connect to server, cant ping server.

Clients can however pull DHCP from server.... Just cant do anything after.

Ran through ICW several times. I did go from 2 nics to 1, tried going back but still doesnt work.
Disabled nic, checked DNS and DHCP, works fine from server. Server still pulling pop mail, intranet page still works from server.

Cannot even ping router from server. HELP
Ipconfig is all right.

Please post the IP configuration of your server NIC card. Also check DNS on the server to be sure that the server is listed with A and NS records. In the process of removing the second NIC card, did you change the internal IP address of the server?

Yes I did Use the change IP address but not until after I tried the following. I disabled one nic, removed IP, ran ICW and changed to single nic through wizard. I then got duplicate IP issue (even though I did remove IP) So after reboot I disabled Nic in Bios, and ran change IP wizard.

I checked Registry and checked to make sure the guid on nic was correct.

DNS shows A AND NS records for server with correct IP

Sorry to be so delayed getting back to you - I had no electricity anywhere in my life (home or work) for the past 36 hours!

Are you still experiencing this problem? The IP config on the server looks fine. You have 192.168.1.253 set as the default gateway here - is that the Sonicwall?  I assume the Sonicwall now is connected to a network switch?

What is the IP scope and options that the DHCP server is using - i.e., range, subnet mask, DNS and default gateway particularly?  
Hi, there are several possible problems, please try to check the following:
1. What is strange, that you have node type - unknown. Try to change it to hybrid by modifying the registry key below:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\NetBT\ Parameters\NodeType
HKEY_LOCAL_MACHINE\System\CurrentControlSet\NetBT\ Parameters\DhcpNodeType
Just set it to the value of 8 (hybrid), reboot and check if something changed.

2. on some client machine install Wireshark (www.wireshark.org), start it and then open command prompt and type "ipconfig /renew". when you will receive some IP address, look in wireshark for broadcast messages (especially the packets called DHCPDiscover, DHCPOffer, DHCPRequest, DHCPAck) and examine the source IP of the DHCP server - is it the same like you have on the server? Also check the MAC address - is it the same like the one on server NIC?

3. Try to disable firewall on the server - at least temporarily to see, if this is the cause of the problem.
