Hello, I have a small network of 5-6 machines, win2003 file server and naked dsl speedstream router. I recently had to change ISP, unfortunately they don't have good technical support. I currently have internet but the clients leases are not being automatically renewed. I am aware that DHCP is down but can't get it working. I can rectify the client ips by rebooting the router every 3 days or so.
My old TCP binding on the server was IP 192.168.2.2 Sub 255.255.255.0 Default Gateway 192.168.2.1 DNS 192.168.2.2 The new ISP has given me these details but I am not sure how to proceed. Subnet 64.235.209.64/29 I'm really curious about the 29 IPs 64.235.209.65 thru 71 Mask 255.255.255.248 Any help in implementing would be appreciated. Thanks |

Easy stuff first... The /29 is basically saying you have 8 IPs.
The 64.235.209.64 is the gateway/primary IP for the other IPs that are assigned to you. The remaining 7 are assignable to devices. I'm guessing your router is 192.168.1.1. If I were you, I'd assign a static internal IP of 192.168.1.2 to the Win2k3 server and make it your DHCP server. It will allow you WAY more options in assigning IPs to the client computers. If this is an option, let me know and I can provide further information for you. |

Brian, Thank you for your quick response. Unfortunately when I try to reply to your post I get a message that says I do not have permission to access the page and that may be a problem at this end. I tried to email you but apparently that function is not working.
In any case, yes I can use the Win2k3 server for DHCP. In fact it was set up that way when it was initially installed by the technician with the previous ISP. The settings are still active but there is something I'm missing. Thanks |

I've changed your permissions in the forum so you should be able to reply now....not sure why you couldn't reply....thanks for letting me know, I've got something set incorrectly and need to get that fixed.
As for the dhcp server in 2k3, you'll have to disable dhcp in the router so the network pc's will go to the server to get their IP. It might be best to assign a static IP to one of the workstations with the gateway and the dns as the 2k3 server and make sure you can surf, etc. |

I think DHCP is working on the server as it has a green light. I disabled dhcp on the router but now I am not sure how to assign a static IP to one of the workstations with the gateway and the dns as the 2k3 server etc.
But I do think the network is responding well. Thanks |

Whatever the DHCP Scope is in the 2k3 server, just assign one of the workstations an IP from that scope....as long as that IP is not in use on another machine. Ping it and if you don't get a response, chances are, it's not in use.
To assign a static IP, see our How To Change Your IP Address article and follow the instructions for your OS. In step 9 or 10 depending on your OS, is where you'll plug in the static IP. The network will probably continue to run with DHCP turned off on the router until it's time for a new lease. When the workstations then try to renew their IP, the router won't respond and they'll drop the IP they have. This is why it would be best to assign a static IP to a workstation that points to the server first to make sure the server is working with DNS, etc. before shutting off the DHCP in the router....unless the other workstations aren't being used...then you're free to do as you please. |

All my machines are working well. However, although the ip supplied by the isp is 64.235.209.64/29, what is my ip is showing ip of 72.0.210.56 but sometimes revert back to 64.235 etc.
DHCP on the router has been disabled and DHCP on the win 2k3 has a green light and the scope is 192.168.2.1 to 192.168.2.254. The people at the 3rd party server who host our websites are not happy with this arrangement. Thank You |

the IP address you get when you go to whatismyip.com is the IP assigned by your ISP's DHCP server, not the DHCP server in your router

OK.. fair enough but my isp assigned me static ip's 64.235.209.65 thru71 but the whats my ip is Your IP Address Is 72.0.210.56.
So this confuses me, the internal ip is 192.168.2.1 a total of 3 different sets of ips? Thanks |

Where are you looking that you are getting that 64.235.x.x IP?
The 192.168 IP is normal (see the link in my signature for explanation) |
