The DHCP allocator has disabled itself on IP address 192.168.1.11

[aa]

In the System Event Log I have a lot of entries like this:

The DHCP allocator has disabled itself on IP address 192.168.1.11, since the
IP address is outside the 192.168.0.0/255.255.255.0 scope from which
addresses are being allocated to DHCP clients. To enable the DHCP allocator
on this IP address, please change the scope to include the IP address, or
change the IP address to fall within the scope.

I did not set the addresses - I have it set to obtain IP address
automatically

How do I change the scope ot the address?

2 possible reasons:

1) You have a 2nd NIC in the DHCP server (or Internet Connection Sharing
enabled workstation) that is configured with an address of 192.168.1.11.

2) You have a 2 IP addresses on your single NIC in the DHCP server (or
Internet Connection Sharing enabled workstation) with one of them being
192.168.1.11.

Thanks Chris.

1. The second possibility makes more sense, for both computers in my
"network", if you done mind me using this name for two PC attached to a
router, have just one NIC each. Unless the router (Vigor2600X) has two
NICs - is this a possibility?

2. Having two IP addresses on your single NIC in the DHCP server (or
Internet Connection Sharing enabled workstation) with one of them being
192.168.1.11)

My problems seem to start when Lucent VPN was installed. It resulter in the
second NIC appearing in the Device Manager. The secod NIC is exactly the
same as the first one appended with Lucent VPN miniport - is there a chance
that it has a wrong address.

However it looks like the address is OK but the address scope it set wringly
on that secind NIC, because the other PC on the same network has
192.168.1.10 autopmatically assigned and it its Event viewer does not show
the above Error.

What do you think of it?
