2nd NIC troubles
Hi All,

eth0 is the virtual IP from PFSense mapping connected to the router, works
fine.
eth1 is a second NIC that I have assigned a private IP to and connected it

know this setup works.
When I connect the cable to the switch and bring up eth1 the system
basically stops taking

DNS Proxy - WINS problem - please help
Here is my scenario when a client wants to resolve a name on my local
network:
CLIENT --> VPN --> SAMBA --> DNS
The client is set up like so:
DNS1 = ISP DNS1 (204.26.64.1)
DNS2 = ISP DNS2 (204.26.80.3)
WINS1 = my samba1 (10.10.1.5)
WINS2 = my samba2 (10.10.1.8)
This all _seemed_ to have worked 3 days ago for roughly 6 months but
stopped suddenly without me doing anything.

Question about adding DNS records
Hello all,
I managed to install an extra DC.
The first DC is comsrv01a with ip 192.168.0.200.
I run Samba 4.1.9 and BIND 9.8.1-P1.
The new DC is srv01ham with ip 172.16.32.222.
I use the internal DNS.
I run Samba 4.1.9.
I use a permanent LAN-2-LAN VPN via my Draytek routers.
The first DC (comsrv01a, 192.168.0.200) is my primary DNS server. This is
configured in all my routers and DHCP servers.

DLZ Backend DNS Hosed
I've been working on this problem for a few hours. Here are some updates:
Many of the domains I listed are duplicates of domains managed by other DNS servers on my network. There was no point in having them in Samba AD, so I deleted the zones in Windows DNS Manager and created slaves in my named.conf.local folder, so that they'd pull the records from my authoritative BIND DNS server,

NetworkManager constantly overwriting /etc/resolve.conf - how to disable?
Hi all,
I have a CentOS 5.4 server-only installation, i.e. no X installed, and
for some odd reason /etc/resolve.conf gets overwritten by
NetworkManager on a constant basis. I haven't been able to track down
how often, but I think it's on the hour, or something.
This is the conents of the file right now:
