• Vista Enterprise doesn't find logon servers in a network with 802.1x authentication

  - by jneves

  In a network with 802.1x configuration and a samba server configured in the domain, I have a radius server that delegates the authentication against the samba domain for users (using LDAP). The radius defines which VLAN the user is supposed to have access. I'm trying to put a Windows Vista Enterprise in the same network, but it attempts to logon the domain before authenticating against the network in 802.1x and it doesn't find any logon servers. In the radius logs I see the machine trying to authenticate with 'host/'. Does Vista enterprise require that I put it in a network with access to the logon server at that point? Thanks in advance, João Miguel Neves

• wireless access point

  - by Warren Bullock III

  I'm hoping to get some suggestions for possible Wireless Access point/router models which will allow us to have two separate networks. We run an internal network on 10.x.x.x IP range where we have shares and other network resources for which we would like to have our regular users access. However, we would also like to offer a separate wireless network for guests which ideally would be on 192.168.x.x and these users would not be able to see any of the resources sitting on the 10.x.x.x network. Anyone have any recommendations on single devices that might be able to get the job done? I was looking at the Linksys E4200 and it seems to support what I'm looking to do... any others? Thanks in advance for any suggestions.

• Slow network file transfer (under 20KB/s) on newly built x64 Win7

  - by Mangoshake

  I am getting <20KB/s for local network file transfer. If I transfer a very small file (less than 100KB) it would start quickly then slow down to <20KB/s. all subsequently network file transfer would be slow, a reboot is needed to reset this. If I transfer a large file it would be stuck on calculating for a long time and then begin with <20KB/s immediately. This is a newly built desktop running Windows 7 x64 SP1. Realtek gigabit LAN from the motherboard (ASRock Extreme3 gen3). Problematic speed is observed on the private LAN, both through ethernet and WiFi. The Router is D-Link DIR-655. Remote Differential Compression is off. Drivers are up-to-date from ASRock's website. I have tested network file transfer to and from another Windows 7 laptop and a MacBook Pro, so I am fairly certain it is the desktop's problem. The slow speed only happens with one direction also, outbound from the desktop, regardless of whether I initiate the file transfer action from the origin or the destination. Inbound network file transfer and internet speeds are fine, so I don't think this is a hardware issue. I am getting 74.8MB/s internet upload speed from speedtest.net (http://www.speedtest.net/result/1852752479.png). Inbound network file transfer I can get around 10-15MB/s. I am hoping this community has some insight for me to troubleshoot this. I don't see anything obviously related from the Event Viewer, and beyond that I just don't know where else to look. Any suggestions are greatly appreciated, thank you in advance.

• Wireless Network Disappearing From Available Networks (Windows 7)

  - by PeteDaMeat

  I have been using Windows 7 with a BT Voyager wireless adapter to connect to my home wireless network for around the last 6 months or so and until recently have experienced no problems. However, over the last couple of days Windows has been unable to connect to the network and the network name is no longer visible in the list of available wireless networks. The only way I have got round the problem is to reboot the NetGear router and to change the SSID to a network name which has not already been used. I do not believe the problem is with the router as my mobile phone can connect to it without any problems. The BT Voyager wireless adapter detects all other available networks so I presume this is a Windows 7 issue as it seems to occur when the PC is rebooted. This problen has happened twice in the last 2 days and is becoming extremely annoying. Does anyone have any suggestions?

• Network driver for Hyper-V restore from Windows Home Server

  - by Philipp Schmid

  I have backed up Windows Server 2008 running virtualized on Hyper-V to a Windows Home Server 2008 SP1 (I know I should have backed up the VHD instead). Now I need to restore the contents of the VM from WHS. I have created a restore CD ISO and used it to create a new VM. It all works as advertised up to the point where the restore process wants to load the network drivers (it only finds 4 disk drivers on the restore CD. but no network drivers). So I created a virtual floppy and copied the contents of 'Home Server Drivers for Restore onto it. But no luck! I have tried moving the 4 subdirectories into the root of the floppy, but that didn't work either. Finally, I started another instance of the WS 2008 to identify the network driver that the virtualized instance is using (%WINDOWS%\system32\drivers\netvsc60.sys) and copied that file onto the virtual floppy, without success. Does anyone have any suggestions on how to get networking working on a Hyper-V instance running off the Windows Home Server Restore CD? UPDATE: As suggested by delenda, I have added a legacy network adapter to my VM, and indeed I now get a network driver listed! However, the WHS it still not found, even after entering the home server name manually. PHS

• Home workers requiring simultaneous office VPN and local network access

  - by jon.simpson.uk

  I now have a large number of remote users that are using a Check Point Secure Client VPN connection into the office. These users also need access to network resources attached to their local router/hub (network storage and network printer). Is there any way that the client (Windows 7 or XP) can be configured to bypass the VPN for local addresses (192.*)

• Shrew VPN Client gives default route- changing the policy stops me from accessing VPN network

  - by Lock

  I am using the shrew client to connect to what I believe is a Netscreen VPN. Now, when connected, the client adds the VPN as the default route. I do not want this- there is only 1 network behind the VPN that I need to access. I found that with the shrew client, you can change the "Policy" settings on the connection, and can add your own networks in that should tunnel over the VPN. I do this, and add my network in, but when I connect the VPN, I get nothing. Can't access the network. Any idea why this would be? I can see my network in the routing table, and its correctly pointing to the correct gateway. A traceroute shows all time-outs, so I can't be 100% sure that it is trying to tunnel over the VPN. Any idea how I can troubleshoot this?

• How to choose which network connection provides the default gateway in Windows XP

  - by Cathy

  I have a laptop with an integrated NIC and a WiFi connection. Both the wired and wireless networks I am using can access the Internet. Win XP is routing all traffic through the wireless network. I want to force it to route everything through the wired network when it is available (i.e. when I am sitting at my desk with the laptop docked) and through the wireless when that is the only option (i.e. when I have undocked my laptop and carried it to a conference room, or if I am out of the office working on a different WiFi network). The wireless connection cannot be established until after I am logged into Windows, so it's always the second network to become available to the OS. I have manually overridden the metric values in the TCP/IP configurations so that the NIC has metric 10 and the WiFi has metric 20. However, Windows is still picking the WiFi adapter's address as the Default Gateway, so this isn't helping. If I manually disable and re-enable the WiFi adapter, then it will switch the default gateway to the wired network and stay that way until I shutdown Windows. How can I tell Windows XP not to replace the default gateway when the WiFi connection is first enabled?

• How to stop Windows 7 from automatically connecting to unsecure wifi network

  - by Remi Despres-Smyth

  One of my neighbors has an unsecure wifi network called WLAN. At one point in the past, I accidentally connected to it, and disconnected immediately when I noticed. Now, when I open my laptop at home, it sometimes connects to the WLAN network first, before trying my (secured) home wifi network. The information I've found regarding this issue seems to suggest this network should have a profile on the "Manage wireless networks" screen - but it does not. How do I tell Windows 7 to never connect to networks with SSIDs called WLAN? Or to never connect to unsecured networks without confirming with me first?

• XenServer VM's lose network settings

  - by Ash

  We deploy virtual machines using Citrix XenServer 6.0 for our clients. Two seperate clients experience the same issue: when a Server 2008 virtual machine is restarted, the static IP addresses (network address, subnet, gateway, primary DNS) don't appear to apply correctly as the IP's cannot be pinged, network services cannot be accessed etc. The issue is resolved by manually switching the network adapters to DHCP, then re-setting them to the original static IP's. While not a major issue, it's a pain when restarting servers due to Windows Updates, plus iSCSI drives need to be manually connected to Windows again via iSCSI Initiator. We have tried removed the network adapters from the virtual machine under XenCentre but without luck. Anyone experienced similar issues?

• Teamed network cards on a Proliant Server

  - by Matt

  We have 4 network cards in a Proliant server with Server 2008R2 running Exchange 2010, with 1 card set to a static IP address and the other 3 set to DHCP. I just need some clarification as I have not teamed network cards. Do all the network cards need to have a static IP when I set as a team. The connection that has the static IP is the IP that I need to use for the Server. Is it possible to set the teamed cards to the same static IP or do I have to change the static IP to another IP then use it for the teamed IP? I will be using HP Network Configuration Utility to set this up.

• LXC container can only access host via bridge

  - by vitaut

  I have an LXC container with i686 Ubuntu 12.04 running on a x86_64 Ubuntu 12.04 host. I've set up a bridge using instructions here. However the ping from the container only goes through to the host and not to other machines on the local network. Similarly only the host and not the other machines see the container OS. The host's /etc/network/interfaces file looks as follows: auto lo iface lo inet loopback iface eth0 inet manual auto br0 iface br0 inet dhcp bridge_ports eth0 bridge_fd 0 bridge_maxwait 0 The container's /etc/network/interfaces file looks as follows: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp And here's the relevant part of the container's config: lxc.network.type=veth lxc.network.link=br0 lxc.network.flags=up Any ideas what I'm doing wrong?

• SharePoint site access request denied permissions

  - by Nat

  Here is a good catch-22. When a user without any permissions on a site requests access from the _layouts/AccessDenied.aspx page it takes them to the Request Access page (_layouts/ecm_reqacc.aspx). When the user fills out the form with a simple message it is supposed to send an email to the address specified in the site collection and take them to _layouts/confirmation.aspx. Unfortunately the users are getting another access denied error instead. I have tried going to _layouts/accessdenied.aspx on a site I am the administrator of and the email is sent fine, so it is not a problem with sending the emails. What should I check and/or give access to in order for authenticated, but not permissioned users the ability to send access requests?

• open source solution to a gateway for a network of a housing cooperative of 150 people

  - by SirDinosaur

  i just inherited a barely functioning network for a student housing cooperative of about 150 people. in it's current state, as i understand it from the previous person in charge of the network, we have working wireless access points and working ethernet cords going to working gigabit switches going to a barely functioning gateway (right now a simple home router) to one of three possible outbound connections. it is possible to connect to the network through the wireless or ethernet, but especially during peak hours, packets / connections are likely dropped or otherwise get no response. my intuition tells me to replace the gateway with something that can handle multiple outbound connections (WAN) and one inbound connection (LAN), while the rest of the network seems suitable for now. i'm somewhat knowledgable in Linux (been using Debian after first Arch Linux) and i want to use as much open source as possible, but i'm confused whether or not a simple server that i could easily understand will work for this situation. do i need specialized hardware to handle the switching more effectively? if so, what are my options? (i found this, thoughts?) or if a Debian server would work, anything else i should about the specs required for this type of server? also links to any useful information on using open source to maintain this type of network would be most appreciated. <3 P.S. crossposted http://redd.it/yybp2.

• Encrypt LAN and wifi traffic on small private network

  - by Grimlockz

  I need some advice about encrypt all traffic on a small private network running wi-fi and LAN traffic on 192.168.0.x network. The network would comprise of client laptops connecting to the wi-fi router (192.168.0.254) via ethernet connection or wireless. The main purpose of the server is for the client laptops to talk to two servers on different IP's (192.168.0.200 and 192.168.0.201) on ports 80 and 433. My main concern is having packet sniffers and what not getting access to the data. The only ways I see at the moment is to have VPN running on the network or use IPSec policy's to do this. Any other ways guys?

• Connecting 2 different subnet masks

  - by Jonathan

  I'm no network genius, but I have managed to get most things running. I get confused about subnets and gateways though. We have an office server connected to around 20 PC's that all communicate fine. We have just gotten a cutting machine that won't connect to our network. The server has DHCP, but that fails on the cutting machine, so I've been trying to set the IP manually. Server details are as follows: IP: 10.1.1.12 SUBNET: 255.255.255.0 GATEWAY: 10.1.1.1 Internet connection is via the modem which is 10.1.1.1 An office PC is ussually set up through DHCP and has the following settings: IP: 10.1.1.36 SUBNET: 255.255.255.0 GATEWAY: 10.1.1.1 PRIMARY DNS: 10.1.1.12 Cutting Machine computer has 2 network ports. 1 is specifically for the communication between the PC and the cutting machine. It's details must be as follows: IP: 10.100.100.2 SUBNET: 255.255.255.252 GATEWAY: BLANK The other network port need to connect to the server. I was told that the IP and SUBNET need to be as follows: IP: 10.100.100.1 SUBNET: 255.255.255.252 GATEWAY: ?? How can I connect this port to the server and/or the internet. If anyone can offer assistance, it would really be appreaciated.

• How to connect a Bluetooth network connection using the command line

  I can enable a Local Area Network interface for my machine with the command netsh interface set interface "Local Area Connection" ENABLED Is there an equivalent command to connect a bluetooth network connection? I've tried netsh interface set interface "Bluetooth" ENABLED but it seems to have no effect, the connection remains disconnected. I also tried netsh interface set interface "Bluetooth" connect=CONNECTED but this returns One or more essential parameters not specified I know this Bluetooth connection is otherwise ok since I am able to connect using Control Panel Network Connections, right-clicking on Bluetooth Connect.

• How to troubleshoot intermittent and irregular connection errors on home network (preferrably Mac client)

  - by Martin

  Hi, I'm experiencing intermittent connection errors in our home network from two different computers, normally "Connection Reset" when browsing, but also other issues such as very slow throughput. I have approximately a network setup as below: ISP-Cable Modem-Dlink DIR 655 Router-(Ethernet)-Fon Router-Mac/Windows laptop Basically, is there a simple way to monitor the network and detect where issues are coming from? Right now we don't know if it is the Fon router, the Dlink router, the modem or the ISP. As the issue is intermittent, is there a software that regularly traceroutes a set of destinations and tests e.g. throughput, something that can help us figure out where in the chain the errors are introduced? The more automatic network monitor, the better.

• WiFi: Connect to a network with hidden SSID in Windows 7

  - by Dor

  I have Windows 7 with the following station: D-Link DWA-160 Xtreme N Dual Band USB Adapter(rev.A2) (driver version 3.5.0.21). I'm trying to connect to a wireless network that has an hidden SSID with the command: Netsh wlan connect name="myNetworkProfile" The profile is configured to connect even if the network is not broadcasting its name (SSID). Despite that, the command fails promptly every time with the message: The network specified by profile "myNetworkProfile" is not available to connect. Nonetheless, when trying to connect manually using the dialog box (see image below), it successfully connects to the network after about 10 or 15 seconds. Also, Please - no need to elaborate about how useless the hidden SSID feature is.

• Network trials and tribulations

  - by MauiWowie

  Hi, I am in the process of setting up a small (two PC's, both running Windows 7) network using a D-link DI-604 router (which acts only as hub, it's not set up in any way). In the Network and 'Sharing Center' in 'Control Panel' I clicked 'Set up a New (Connection or) Network'. All went well up until the moment I attempted to connect one PC with the other (in the 'Connect' dialog I entered the other PC's IP, no pwd). I can use both PC's to connect to and browse the net though, so the router/hub does not seem to be the problem. And I must have done something right, because the other computer shows up in the 'Network Map'. Any and all help is much appreciated!

• Routing from the DMZ to the interior network only

  - by Allan

  I have a home network connected to Verizon's FIOS service. Verizon's ActionTec router is connected to the ONT via coax to establish the MOCA network. My DD-WRT router's WAN port is connected to one of the ActionTec's LAN ports. The DD-WRT router is configured with a static IP address and assigned to the DMZ (this is done so I only have to configure port forwarding once). My issue is that this does not allow computers connected to the DD-WRT to serve streaming audio/video to the MOCA network using Verizon's Media Manager. I know that Media Manager uses ports 18001, 5050, and 5060, but I don't know how to forward those ports so that they are only available to the ActionTec's network and not the rest of the internet.
