Hi,

Just installed Windows 2003 Server Standar and trying to go online from one workstation, but can not.

Let me give some details about network setup.

Internet and network:

Time Warner cable, dynamic IP
Verizon DSL, Dynamic IP

Both connected to Xincom 2xWAN VPN Gateway/router with 4x100 port switch, IP: 192.168.2.1. DHCP: disabled. One port of the router is connected to 12-port Gigbit switch, all workstations and server are connected to swich.

Server:

Windows 2003 R2 Standard.
IP: 192.168.2.2 / 255.255.255.0

During AD installation installed DHCP and DNS server, both of them started as per list of services.

C:\Documents and Settings\Administrator>ipconfig /all

Windows IP Configuration

   Host Name . . . . . . . . . . . . : mydomain
   Primary Dns Suffix  . . . . . . . : mydomain.com
   Node Type . . . . . . . . . . . . : Unknown
   IP Routing Enabled. . . . . . . . : No
   WINS Proxy Enabled. . . . . . . . : No
   DNS Suffix Search List. . . . . . : mydomain.com

Ethernet adapter MAIN LAN:

   Connection-specific DNS Suffix  . :
   Description . . . . . . . . . . . : Marvell Yukon 88E8052 PCI-E ASF Gigabit Ethernet Controller
   Physical Address. . . . . . . . . : 00-18-F3-E6-24-6F
   DHCP Enabled. . . . . . . . . . . : No
   IP Address. . . . . . . . . . . . : 192.168.2.2
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.2.1
   DNS Servers . . . . . . . . . . . : 127.0.0.1



I can go online from the server, but I can not go online from workstation.  Note that it shows DHCP is not enabled (why ?!?, I can see leases in DHCP applet) and DNS server address is 127.0.0.1 (maybe it should be something else, maybe server's IP or router?).

Workstation is with DHCP enabled and should pickup IP address and DNS address. Below is what ipconfig on workstation:


Windows IP Configuration

   Host Name . . . . . . . . . . . . : support
   Primary Dns Suffix  . . . . . . . :
   Node Type . . . . . . . . . . . . : Unknown
   IP Routing Enabled. . . . . . . . : No
   WINS Proxy Enabled. . . . . . . . : No

Ethernet adapter LAN:

   Connection-specific DNS Suffix  . :
   Description . . . . . . . . . . . : Intel Pro /1000 GT Gigabit Ethernet Controller
   Physical Address. . . . . . . . . : 00-0E-F3-2F-24-24
   DHCP Enabled. . . . . . . . . . . : Yes
   Autoconfiguration enabled. .: Yes
   IP Address. . . . . . . . . . . . : 192.168.2.50
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . :
   DHCP Server . . . . . . . . . . . : 192.168.2.2
   DNS Servers . . . . . . . . . . . : 192.168.2.2
   Lease obtained. . . . . . . . . .: Sunday, March 25....


Workstation is not joined the domain and uses local account which should be not a problem to pickup IPs, I think. I've tried to join a domain, but still as part of domain I can't go online andDefault Gateway on the workstation is empty.

How can I verify my setup and find where the problem is? Any tools?

Thank you.

When the server says DHCP Enabled: NO, this means it is not getting an address itself from DHCP, which is a good thing, as you cannot have a DHCP Server without a static address.


The problem on the workstation is that it does not have a default gateway, so it does not know how to get traffic outside your network. In your DHCP scope, set the option for "003 router" to 192.168.2.1

Just in case you don't know how.

Oopen the DHCP console on your server.(from administrative tools or "dhcpmgmt.msc")
Expand you server and scope, then go to scope options.
In there you will likely not see an entry for "003 Router". Right click in the right hand window and go to configure options.
Highlight 003 Router, and tick the box. Add teh IP address for 192.168.2.1
Save out of here and then reboot the workstations (or go to run and type: ipconfig /renew

Should work fine as long as that is the only fault.

Thanks, Burns2007. I forgot to set 003 Router for DHCP scope. Once I did it, after restart everything is fine.
