Two nics, one server - unmanaged switch

  • 1. static IP error
    i have IBM blade server HS 21 with Broadcom network card and when i assign a static IP to the NIC it gives error this IP address is already in use on network, try assigning another IP. i have tried on 10 servers and same error and i am sure the IP addresses i am tring to assign is not used. when i disable and enable the network card it starts working with the same IP any help would be highly appreciated.
  • 2. 2008 not issuing DHCP addresses
    I'm setting up a lab environment, testing Win2k8 server with XP SP3 and Vista SP1. There are Win2k3 SP2 DC's in the lab network, and the 2k8 box is a member server in the domain. I've installed and configured DHCP on the 2k8 box, primarily because if everything works, I want to secure network access using NAP/DHCP. Problem is, the 2k8 server will not issue any IP addresses. It's authorized in A/D, has a correct scope, the network is working fine as well as DNS. If I set the XP or Vista client to request a DHCP address, they just sit there until they time out, then they self-allocate an APIPA address. Odd thing is, If I run wireshark on the Win2k8 server during the lease discover phase, I can see the packets hitting the Win2k8 server, but it just doesn't respond. I've checked everything I can think of, even changing the NIC in the Win2k8 server (just in case). If I give the XP/Vista clients a static IP, they can see the Win2k8 server fine. I even tried setting static reservations, but no change. If I bring up a 2k3 DHCP server on the same network, the clients get an address ok. When I look at the event log on the 2k8 server, it says it's authorized in A/D ok, and is ready to serve clients. This is really weird. Anyone have any ideas?
  • 3. netsh script to hard-code IP address
    Gurus, Does anyone know a netsh script which would change a DHCP-configured NIC into a hard-coded one which uses a static IP, class C mask, DG of 192.168.1.1 and DNS server of 192.168.1.10?
  • 4. NAS Data Storage
    I am considering getting a Buffalo Tera Server for my home office (not sure which one yet). I want to be able to backup the data from all my PCs and Apple Mac Notebooks. I want the data to be accessible over the internet so my family can backup and access it remotely. I want to use my iTunes database in the home to play music from some music player device in the future (not yet gone that far) hopefully without my main PC being on. Can anyone recommend a good make and model that will do all of these things. I prefer to be able use standard hard disks in RAID mode array. I am not sure whether you can put a disk from a RAID array into an ordinary PC if you need to read the data (so FAT or NTFS format would be preferred) but this would be a bonus if it is relevant. Any suggestions appreciated Graham

Two nics, one server - unmanaged switch

Postby Boe » Sun, 05 Aug 2007 23:43:54 GMT

Hello,

I was curious if there is a way to give my server more throughput.   I 
currently have all gigabit switches (unmanaged).   My server is a 2950 and 
we work with a lot of very large files.    I have enough memory and 
processing power however the network throughput is a little high. 
Currently I have one nic connected.

Thanks

2950? Dell I assume, but the digit alone doesn't tell anything.
Did you install the network drivers, which came with the Dell CD (or have 
they been preinstalled)?
In this case you should find the Broadcom utility in Startmenu / All 
Programs Programs / Broadcom / Advanced Control Suite 2, which allows you to 
configure a team. (You will need 3 IP addresses, one for each physical 
interface and the one for the virtual (teamed).

GOod info - thanks.   I'm looking forward to giving it a try but I need to 
install the latest drivers.   Right now I'm in the middle of transferring 
over a terabyte of data so I don't want to interrupt it.

You have to make sure your switch can handle it.  Since a switch associates 
a MAC Address with a specific single switch port it may lock onto only one 
port (and hence only one nic) and you won't gain anything.

Postby Sm9zaHVhIEJvbHRvbg » Thu, 09 Aug 2007 06:56:00 GMT

You can't do adapter teaming with a unmanaged switch.  Switch needs to be 
managed and support one of the teaming protocols.

Re: Two nics, one server - unmanaged switch

Postby Chris » Thu, 09 Aug 2007 20:24:29 GMT

As long as both NIC's are plugged into the same unmanaged switch you should 
be able to team successfully and get the both NIC's to work as one. The only 
thing in using an unmanaged switch id that you will get 2gb throughput on 
send but only the primary nic will be able to receive data  (1gb)

If you want to get full teaming you'll need a managed switch which supports 
803.2ad standard. You can then have multiple stacks of switches and 
distribute between switches in the same stack for failover.

Usually the manufacturer will supply some teaming software. I have used 
broadcom and intel in the past with no problems

I'm getting lots of good info - THanks everyone - I'm going to give the 
built in broadcom nics a try (which have teaming capabilities)  and we are 
about to try out the new netgear smart switches (semi managed)  GS748TS











Re: Two nics, one server - unmanaged switch

Postby Chris » Fri, 10 Aug 2007 03:16:57 GMT

Looking at the spec Boe you should get full teaming capabilities. One thing 
to check is that you may need to physically pair the ports on the switches 
for the team to work. Some will automatically team if the NIC's are teamed 
and spanning tree is enabled.

One thing to note if you are using 2 switches and not using the stacking 
modules to stack the units (ie using a cat 5 uplink cable) you will need to 
put both nic's in the same switch.

1.Two NICS, Two IP Addresses - ONE SERVER NAME

Setup - Internet monitoring system setup w/ two NICS each has a seperate IP 
address (both in same subnet).  Only one has default gateway setup - problem 
is that it's automatically getting registered in DNS w/ two IP addresses for 
same name which is causing sporradic problems.  Any ideas on how to configure 
this in DNS to eliminate the DNS confusion?

Thanks in advance!

2.Switching from two nics to one

I am currently running SBS 2003 Standard and have two offices both with 
non-static IPs that I need to have a static VPN between.  The main office's 
IP is managed through DYNDNS.org.  Everything I read says that to utilize VPN 
routers I should go to a single nic on the SBS server.  Is this the best 
strategy?  Each office also has a wireless router.  Should the setup be 
Broadband Modem>VPN Router>Server, Wireless router?  Am I headed down the 
correct path?

Skids.

3.two nics one domain one workgroup one pc ?

We are located at a clients location and we are on their 
domain using their dsl. We also have a web/ftp and email 
server that use its own full t1. Out ftp is very slow for 
some reason even though dsl reports show us having killer 
ups and downs. The web guys want to hook directly to the 
ftp server internally since both servers are in our 
office. The programmer and I need constant access to the 
clients location for monitoring we also need access to our 
web server. I tried two nics on my machine made a copy 
hardware profile disabled the one from the domain network. 
enabled the work group to our web server. Problem is you 
log on and your still on a domain with the fully 
registered dns name. So I bump down to workgroup restart. 
And went back into the domain hardware profile and found 
out that it was bumped to workgroup which i dont want. I 
feel like im going in circles. Is there any easier route 
that Im overlooking ? Any help would be much appreciated..

4.One Server, two NICs

Hi,

At present we have a web site hosted in our web server. Because of bandwidth
problems, we use two 2Mb DLSs connected to internet. To connect the server
to each one of the two DLSs we use two diferent NICs. From time to time our
web server seems not replying user petitions, and we don't know if it's
because our net configuration or because scalation problems in the server.

The first ADSL has the internal IP address 192.168.111.252, and the TCP
protocol (port 80) mapped to the first of our NICs at address
192.168.111.114.
The second one has the IP address 192.168.111.253 and is the TCP protocol is
mapped to the second NIC at address 192.168.111.115.

The TCP/IP properties of our NICs are:
IP: 192.168.111.114
Mask: 255.255.255.0
Gateway: 192.168.111.252
DNS: 195.235.113.3 (the DNSs of our ISP)
          195.235.96.90

IP: 192.168.111.115
Mask: 255.255.255.0
Gateway: 192.168.111.253
DNS: 195.235.113.3
          195.235.96.90

Network Load Balancing is disabled in both NICs.
