Default DHCP Conflict



I have a netgear router that is configured as my dhcp
server. If my windows server 2003 software has dhcp &
dns configured, would this cause a conflict? My internet
connection and my network workstation connections are
dropped repeatedly. The only way to reconnect is to
reboot the router. Any suggestions on what else could be
the problem?

Default RE: DHCP Conflict

Having two DHCP server on the same broadcast segment is guaranteed to cause
problems. You should disable one of them.

Default Re: DHCP Conflict

You can only use an additional DHCP Server if it is not handing out the same
set of addresses. Some of those Cable/DSL Routers only hand out a limited
range of addresses. If your Windows DHCP Server is configured to hand out a
range of numbers that does *not* overlap with the ones from the Router you
will be fine, but you better make *sure* you configured it properly.

Default Re: DHCP Conflict

I do not want any additonal addresses handed out. IF I
disable my dhcp on my server 2003 software, should I
disable dns server as well as VPN server, WINS server,
etc...
My router is acting as my dhcp/vpn.

Default Re: DHCP Conflict

Just leave the VPN and WINS alone. The VPN callers should get the IP from
the Router just fine. DHCP is done by broadcasting, DHCP Servers aren't
"specified". The client simply gets the address from the whichever DHCP
Server is the "quickest on the draw".

Default Re: DHCP Conflict

Thanks for the advice. I disabled my dhcp & dns on my
server. Unfortunately it didn't resolve my problem with
the internet/network disconnecting. VPN & WINS are still
enabled.

Default Re: DHCP Conflict

You'd better contact the ISP. It may be an issue between them and the
router. This is especially likely if the connection uses PPPoE.
