Windows Networking Help

Good Afternoon,

I am having an issue and I would like to get other peoples ideas since I'm a little stumped.

I have a home network comprised of 2 desktops, 6 laptops and 1 server.
I have 4 networking devices in my line. They are a Cable Modem, Vonage Device (Phone Modem & Router), D-Link Wired Gb Router and a D-Link Wireless Router.

Network and Computer configurations are as follows:

Network:

Vonage Device - Router - LAN IP 10.10.10.1, LAN IP Range 10.10.10.1-10.10.10.10
D-Link Wired Router - WAN IP 10.10.10.2, LAN IP 10.10.5.100, LAN IP Range 10.10.5.101-10.10.5.199
D-Link Wireless Router - WAN IP 10.10.5.101, LAN IP 10.10.0.200, LAN IP Range 10.10.0.201-10.10.0.254

Computers:

1 Server - Windows 2k3 R2 Ent Ed SP1
1 Desktop - Vista SP1
1 Desktop - XP SP3
5 Laptops - XP SP3
1 Laptop - Vista SP1

Server Roles are Domain Controller (AD), File Server, Print Server, Application Server, Remote Access/VPN Server, DNS Server, DHCP Server.

DCHP is currently diabled on the server because I had problems getting IPs assigned to the computers on my network. I originally disabled DCHP on my three routing devices and enabled DNS and DHCP passthrough but I was never able to get my computers to recognize the server and get an IP assigned. I abandoned this configuration and turned DHCP back on at each of the routing devices and disabled it on the server. The server is however still my DNS server. So each device on the network (All computers and routers) have the server set as the Primary and secondary DNS with the server's DNS set to 127.0.0.1. (primary DNS on each computer being one NIC on the server and secondary being the other)

With this setup I have been able to join each of the computers to the domain and it seems like everything should be working fine. The problem is that I am not able to ping the server from any of the computers nor can I ping any of the computers from the server. They were able to find the server initially for joining the domain but that is almost the only evidence I have that the can see each other. The only other circumstance is that I was able to do a silent push through Symantec Endpoint Protection to install the antivirus client on each of the computers. So I know they see each other intermittently. Each of the machines have internet connectivity and are updating with rhe Symantec Endpoint Protection Server. What is stumping me is why I cant navigate between the machines through a command line or a run line(\\computername\sharename) and I can't remote between machines.

I was hoping that someone may have an idea of what I am overlooking. I have been staring at this for a long time and am running out of ideas. But Symantec Bakcup Exec is not able to log onto the machines and tells me that they do not exist. Also I set the user accounts in AD up to use roaming profiles but they do not seem to have communicated with the DC since I did that because only one of the laptops the profile I set up for them and when you reboot that the machine with the roamin account logged in it says that it could not contact the DC to update the roaming profile. If anyone has any ideas I would very much appreciate it. Thanks in advance.

Do you have a specific need for running a server and AD in your home? Otherwise, your "Domain" is WAY too small for the overhead of your network. Work groups are ideal upto 10-12 computers and then you move to a domain to reduce overall work load.

You should really try to diagram some of this because most of what you have in written form does nothing for your network design without details on how devices are connected. I have a feeling your design has some serious flaws and your configured improperly or inefficiently. Start with the cloud and work your way in with each device as it connects to the next.

Have you tried plugging everything into a single switch or router and seeing it it works or not?

PS: You should consider switching to staticly assigned IPs as your have a set number of devices and you as the only administrator can keep track of what IP's your using.

I appreciate the input. I was able to get it running. You are correct in that this configuration is serious overkill for what I need. I however I am a solutions consultant and so I keep a domain running where I test applications out. So it is helpful to be able to have an active domain. Either way I found the issue. If I could remember exactly what I did I would post it. Either way I appreciate the help.
