RRAS and DHCP Server (same server) problem

By lcarmo ·
Hello,

I have a small company with 10 workstations and 1 server hp 350 g5. It's a Server 2003 with DC role, DHCP, DNS, RRAS Server. I have 2 NIC's because of the RRAS. RRAS is fully configurated, also all the roles. The problem is that DHCP isn't working (no leases for lan). Workstations receive automatic private address. Any ideas ??? urgent please.

Thanks

LC

Have you authorized the DHCP server in Active Directory?

Server 2003 AD requires that all server 2003 DHCP servers be authorized before they start handing out IP addresses. To do this follow these steps (Taken from Microsoft's website)
1. Open DHCP.
2.In the console tree, click DHCP.
3.On the Action menu, click Manage authorized servers. The Manage Authorized Servers dialog box appears.
4. Click Authorize.
5. When prompted, type the name or IP address of the DHCP server to be authorized, and then click OK.

Hello,

I just resolved my own answer to this forum.
There is a software installed in DC (Allegro Surf) that uses by default it's own dhcp capabilities, because this software is a proxy/firewall.
I used "netstat -a -n -o" and saw that a PID where using port 67, default port for server dhcp (listening). I deleted the allegro surf dhcp, and voil? ... all running and ok !

Thanks..

Best regards from Portugal
