Multiple NIC Segregation In Windows?
Jul 11, 2012
I'm in a shop that requires our workstations to have two NICs. One attaches to a router and through to a DCHP internet connection. The other is a static IP via crossover to our instrumentation system. The issue is that these systems can be extremely remote and rely on satellite or 3G Network connections and are not overly reliable. Every time our net connection drops, BOTH NICs reset, causing us data loss from our instrumentation. Any way to separate the connections so that if one drops, the other is left unmolested?

I have a requirement where 3 Branch locations of an organization is connected to their hub location via MPLS.They have an internet connection only at HUB as shown in the diagram (Attached)Now all spoke locations should access internet via hub.At spoke locations is there a way that I can have Cisco 2900 router and dedicate only 30% of the WAN bandwidth for internet browsing traffic.Remaining 70% should be used for accessing applications at hub.
For example if i have 5 Mbps Mpls port at spoke I want to dedicate only 1 Mbps for internet browsing traffic remaining should be dedicated for accessing the application at hub.How can we acheive this? Can it be done by using PBR and rate limiting?

Doing segregation of SSIDs Base on AP , I have the following scenario:
Head Office :
2 SSIDs (HO_WiFi , Guest) , Access Points which are working in connected mode and grouped on the default ap group .
Remote site:
2 SSIDs (Branch_Wifi , Guest) , Access Points working in flex connected mode and locally switching the traffic .
As shown above , I will be having Head Office , and other 20 Remote Sites with Access Points working in Flex connected mode. What is the best way to group AP and segregate SSID base on location. Above Scenario are build base on WLC 5508 and AP 1142.

I have 4 computers with 3 LAN cards (1 onboard + 2 PCI) installed on each of the machines. One of the machines run Windows Server 2008 and other 3 run Windows XP. I am trying to simulate routing on these desktops. I have connected all the machines in a mesh topology. Please refer to the image attached. I am able to ping all the 3 machines from the server machine. However when I try to ping the machines from the client PC running XP, it is able to ping only one machine connected to it. All the network cards on the client machine running XP show that they are connected (in control Panel-> network connections). But ping packet shows only one host is reachable. The other two network cards(that are not able to ping other machines) are showing red light. I am not able to get over this.

As we all know, MS has changed the default workgroup names in different versions of windows. Additionally, you can rename your workgroup anything you like. I have XP, Vista, and Win7 computers, a television, BluRay player, a Wii, two printers, and a NAS with two USB drives attached. All of these -except the Win7- are wired to one of two switches. I have wireless: iPad, the Win7 notebook, Nintendo DSs. I have friend, and non-friend machines (computers, tablets, and phones) that come and go that are wired or wireless. The 3 windows computers all have the same workgroup name. All of my other units do not use workgroup names. I have a router, and two unmanaged switches, and have, on occasion, a second router. The main router, which has wired, and dual band wireless (each with two named wireless networks) nets, sees everything, by name and/or MAC address. Win7 is blind, deaf, and dumb.: it shows its own workgroup name, but no other workgroup name(s) , and, consequently, no unit on these other workgroups. It will show some wired units not in a workgroups - the television, and the printers (not the Wii or NAS). It will not show the wired XP computer! No wireless units either in workgroups or not in workgroups appear. Additionally, Win7 only shows units on its wireless network, not on the other three. The wired units it does show are not on any of the wireless networks, though it lists them on its wireless network.I have left the Homegroup, and terminated the Homegroup services. I have allowed discovery, and unlimited sharing of everything on every computer on the router, and yet the Win7 unit does not share or see well at all.Why?

I have a Windows 7 Pro Desktop with an on-board Ethernet and an Axis USB To Ethernet adapter. The on board Ethernet is configured as dhcp and obtain the address 10.162.146.123 with 255.255.255.0 subnet. The Axis USB to Ethernet adapter is static ip configuration with 10.38.25.37 and 255.0.0.0 as subnet. Under the adv settings I have also another ip 11.38.25.37 with 255.0.0.0 subnet. When the Axis is communicating 10.38.0.1 network I can not access the internet using the on board Ethernet 10.162.146.123. I have to disable either one of the cards to access one network at a time.

My phone is a Nokia-N900, and I find the most useful way to interact with it from my PC is by ssh. Luckily it is possible to switch out the usb-networking module in the devices kernel to make it appear to windows as a generic RNDIS gadget. Plugging it into a windows PC I can now ssh into it, I can open an sftp session, everything works perfectly...
Except I can't access the web. I can't view other network resources. I look in the network connections section in the control panel and see my two connections, but I don't see any way to set which one to use for what. Seeing as I only use usb0 for ssh and eth0 for everything else, it seems I need a way to set it up so that usb0 only gets port 22 or something similar.
Is there any way to achieve this, or another method by which I could leave my phone connected to my Pc while using it for other network tasks?

We have multiple RA VPN groups on a 3845 router.RADIUS authentication is currently happening between the 3845 and a single Windows 2008 server. We have a specific windows group that AD users are members of, and they are allowed to connect via VPN.
I'm creating a new RA VPN Group, which should only allow different AD users. Is it possible to create another RADIUS association to the same server, or do I need to authenticate against a different Windows server?

I'm working with a 1113 ACS device running the 4.2.0.124 software. I'm trying to get multiple network device groups to use an existing Remote Agent set up for authentication against our Windows domain. For instance, we want our infrastructure switches to authenticate agains the local Active Directory and our WLC to authenticate users agains the same Active Directory. When I try and set both network device groups to use the same remote agent, it fails and reports either the host name is already in use or the IP address overlaps with an existing remote agent.
The question is:
Can I have multiple network device groups use the same remote agent? Or do I have to install the remote agent software on separate Windows servers in order to have different types of devices authenticate against the Windows AD?

how i can configure a second ssid for guest access in our environment. this is our network setup prior to this request: Internet----Firewall (not ASA)---ce520---C1131AG and CME router is also connecting to the ce520 switch. we only have two vlans: one for voice and two for data.
Presently, there is no vlan configured on the AP because it on broadcasting ont ssid and wireless users gets IP from a windows DHCP server on the LAN. the configuration on the ce520 switch port for the AP and other switches say access vlan is the DATA vlan which automatically becomes the native vlan for all trunk port connecting the AP and other Stiches to the network.
Now with this new requirement, i have made my research and i have configured the AP to broadcast both the production and the guest Vlans. The two vlans are 20-DATA and 60-Guest. I made the DATA vlan on the AP the native vlan since the poe switch is using the DATA vlan as native on the trunk ports. I configured the firewall to serve as DHCP server for the guest ssid and i have added the ip helper-address on the guest vlan interface on all switches while the windows server remains the dhcp server for the production DATA Vlan. I have confirmed that the AP, switches can ping the default gateway of the guest dhcp server which is another interface on the firewall. I can now see and connect to all broadcasted ssids but the problem is I am not getting IP addresses from both the production dhcp server and guest dhcp server when i connected to the ssid one at a time. My AP config is attached below.
Do i need to redesign the whole network to have a native vlan other nthan the data vlan? Does the access point need to be aware of the voice vlan? Do the native Vlan on the AP need to be in Bridge-group 1 or can i leave it in bridge-group 20?

I am trying to build a new network from scratch, I have the WLC 5508 w/ Aironet 3600e APs connected to my Netgear Smart Switches and a Linksys RV082 router that I'm using as my DHCP server with several VLANs for several stuff on my Switches.
I have 2 questions:
1. Can I have 5 Interfaces configured on 5 different VLANs, each SSID on each a different Port:
Port 1: Controller management only=> 192.168.x.x /24
Port 2: SSID 1: WiFi Internal=> 172.16.x.x/12 (Radius Auth with no sharing)
Port 3: SSID 2: WiFi Internal w/ sharing=> 192.168.x.x/24 (Radius Auth with sharing)
Port 4 :SSID 3: WiFi Guest=> 10.0.x.x/8 (Web Auth)
Port 5: SSID 4: WiFi IT=> 192.168.x.x/24 ( Radius or certificate Auth with access to the controller management interface)
2. How can I use the Controller as the DHCP server for all the WiFi traffic, and how should that be configured to work with my other DHCP server?

i`m facing a problem configuring the mentioned access point to act as stand alone access point with multiple SSID assigned to differnet VLANs the problem is that
1) i`m not able to broadcast the both SSIDs in the same time from the Access point
2) i need to make the radius server to manage the SSID access for the wireless clients (trying to find a way in which the aceess point sends a log for the radius server containing the VLAN id /IP address of the the SSID) you may find the below info about the IOS ver. & the configuration?
i`m running IOS /c1100-k9w7-mx.123-8.JEE/c1100-k9w7-mx.123-8.JEE?

Is it possible to assign a single ssid to multiple interface groups by assigning the ssid to multiple AP groups?
I have buildings geographically dispersed that are configured with multiple vlans in interface groups so that I can maintain an addressing scheme of dhcp assigned addresses per building. Each building is also further grouped as AP groups. I'd like to know if by assigning the same wlan ssid to each of the AP groups, will I maintain addressing integrity for each building? I'm thinking it will work.
Do the buildings have to be outside AP range of each other to avoid problems?
5508 controller
7.2.110.0 code
6 buildings
6 interface groups
1 ssid

We have a network of approximately 20 computers, network printers, and one Windows 2003 Server (used simply as a file server). I have an issue with two specific Windows 7 Pro workstations that just will not logon. The username and password details we're using are correct, but the server rejects them. I can logon using the same account from any other Windows 7 Pro workstation, or Windows XP station, so I know the issue is specific to the two workstations communicating with the server.
Both afftected stations show Logon attempted by: MICROSOFT_AUTHENTICATION_PACKAGE_1_0 error 0xC000006A which all searches on Google point towards incorrect login credentials, however I've tried plenty of perfectly valid login credentials and they don't work either.I've tried checking that the 128bit option on the Windows 7 machines is disabled in file sharing etc.

I have an RV042 setup for quick vpn access.The remote computer in question is a win 7 64bit. The PC uses McAfee SAAS firewall. This disables the windows firewall.
1. I can connect to the vpn with SAAS disabled and windows firewall enabled.
2. I cannot connect to the vpn with both windows firewall and SAAS disabled.
3. I cannot run SAAS and windows firewall together to check if this would work.
I need to figure out what windows firewall is doing to allow the vpn to connect, and so how do this with windows firewall disabled. I can then leave the windows firewall disabled and enable McAfee SAAS.The message quickvpn provides when it fails to connect is that the remote gateway is not responding. The client logs show that the tunnel had been opened but it was unable to ping.

I have a win xp laptop which connects via wireless to a cheap belkin router I have a Win 7 pro laptop which is hardwired to the router. The Win 7 machine is NOT set up for home groups. We are all on the same workgroup.
I have added the user name from the XP machine to the Win 7 pro machine with admin rights. I shared a folder on Win 7 and added the user name and gave read/write rights. I have no software firewall.
When I try to connect via win explorer via the workgroup I see the Win 7 machine (after 10 seconds). I see 'User' folder which I can browse and I see the folder that I shared but I can't access it. Access denied...

We have a working configuration for L2TP-IPSec connection from a native Windows XP client to the ASA 5510. When trying to set up a connection from a Windows 7 client, the connection fails with the message that all SA proposals are unacceptable? Is this coexistence possible, and what parameters would I have to change to get this working. I have understood that the Windows 7 client requires som higher security proposals, but have not found what these are. And at the sam time we are concerned about not destroying the VPN connection for our existing XP clients.

My Win7 laptop was unable to ping another WinXP within the same network. When I first got this Win7 laptop, I experienced this problem. The WinXP laptop has no problem pinging the Win7 system. A visiting friend changed the setting on the Win7 laptop and suddenly the two laptops were able to talk to each other. I wiped the WinXP laptop a few weeks ago. Since then, the Win7 laptop is again unable to ping the WinXP. I have googled for many hours now. I tried just about all the methods that make sense to me but still cannot ping from Win7 to WinXP. How I can reestablish communication between these 2 systems on the same network?
