  • 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.

  • 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

  • Networking not working in Windows 7 - "The account specified for this service is different from the account specified for other services"

    - by tog22
    I have a homebuilt computer with a GA-Z68MA-D2H-B3 motherboard with a Realtek RTL8111E LAN chip. Ethernet was working fine in Windows 7 until I reinstalled this OS, but now it's stopped, while still working in other OSes. I've tried reinstalling drivers from both the Gigabyte and Realtek sites to no avail; I've also plugged in and installed an Asus USB-N13 wifi dongle and this doesn't work oddly. How can I diagnose and fix this issue? In 'Network and Sharing Center' says "The account specified for this service is different from the account specified for other services running in the same process" under the heading 'Unknown'. Following the advice at http://www.sevenforums.com/network-sharing/130159-dependency-service-group-failed-start.html#post1122627 I've gone to 'Control Panel= Admin Tools= Services' and ensured the services listed at that URL are started (one - IIRC 'Come+ Event System' refused to start as user 'Local services' so I've had to set it to log on with the 'Local system account'... I suspect this may be part of the problem).

  • Can't communicate with Primary DNS Server

    - by horsley
    A computer, with Windows 7, can't access any website by domain suddenly. Whether this computer use a wired link or connect to the WLAN, The fault persists IP and DNS obtained automatically, and seems normal (ipconfig /all return the correct info) I can visit websites by using HTTP proxy The DNS server is available, other computer in my room works properly. I can ping myself, the gateway and any other IP, but domains I can use nslookup and obtain the correct IP info There are some error information in the event log about dns client events explaining the client can not verify the DNS server available Windows network diagnosis explain that Windows can't communicate with the device or resource (Primary DNS Server) I guess the dns client should be blame. I tried to do the following things but the fault persist. Reinstall the driver of network adapter Reset TCP/IP (netsh int ip reset) Reset Winsock (netsh winsock reset) Reset LSP I don't want to reinstall the whole os, what should I do?

  • How do I decrypt WPA2 encrypted packets using Wireshark?

    - by Rox
    I am trying to decrypt my WLAN data with Wireshark. I have already read and tried eveything on this page but without any success (well, I tried the example dump on that page and succeeded, but I fail with my own packets). I caught the four-way handshake from another client connecting to the network. My network info is as follows: SSID: test Passphrase: mypass The above info would give this preshared key: 58af7d7ce2e11faeab2278a5ef45de4944385f319b52a5b2d82389faedd3f9bf In Wireshark in the Preferences--IEEE 802.11 I have set this line as Key 1: wpa-psk:58af7d7ce2e11faeab2278a5ef45de4944385f319b52a5b2d82389faedd3f9bf I have tried the different options of "Ignore the protection bit" but none works. What could I have missed?

  • 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?

  • 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.

  • 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.

  • Netgear router-speed problem after XBox use

    - by John Dudley
    When my son is at my place at the weekend, he plays XBox Live over the internet, using my wireless network (Netgear 'g' type router). This usually thrashes & crashes the router to the extent I have to hard-boot it to get it working again. However, after this weekend, on my two laptops, I'm left with the problem that the router is working, but I'm only getting 0.38Mbps out of it, at all times of the day. I've tried hard-booting the router, but no difference. Could this be a knock-on effect of the Xbox use? I can't believe the router could be damaged, but working slower? Is that possible? Tiscali haven't come back to me yet on any 'network' issues. Thanks in advance

  • 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?

  • Vista laptop won't connect to airport extreme

    - by Hutch
    Our previous router died, and to replace it I procured an apple airport extreme. My mac, my wrt54gs (with ddwrt acting as a bridge) and a linux machine have had no problem connecting to the wireless. None of the wired clients are having a problem obviously. The problem is one of my roommates can not connect. That's not strictly true. He can connect to the network, and will, infact, get a dhcp lease. However he cannot get any packets out. Can't ping the router, can't access any web sites, nothing. However he's fine if we switch to an unsecured network. Which is obviously not acceptable. The airport only allows for 'wpa/wpa2 personal' and 'wpa2 personal' (and of course the enterprise versions there of) I keep reading about this problem in multiple spots on the web, but never see any actual answers... Anyway the laptop: hp/compaq cq50-215nr vista home premium wireess card: atheros 5007 airport is simultaneos dualband II

  • 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

    - by Ed Guiness
    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.

  • Snow Leopard and a Windows network

    - by JohnE
    I have just added a MBP to my home network and while I can connect to the internet etc, i cannot browse my home networked computers. I have already added a new location in my Network preferences yet when I goto the WINS tab, there is no dropdown to select my workgroup so i manually enter it. From what I have read, once I go to the finder and open the network, i should see the workgroup and systems...yet i do not. Any suggestions? Thanks.

  • Can admins monitor my activity locally even when I use a VPN?

    - by Arjun Create
    My school has one of those super overreacting web blockers (specifically Fortisnet) that blocks things that should be accessible by a high-school senior trying to research projects. Despite many students' complaints the administration's hands are tied due to parents' complaints. I have setup a VPN account from http://www.vpnreactor.com. With this I am able to bypass the blocker. I know this service hides my IP from websites and servers on the web. I also know that the school pays an IT guy just to monitor sites and network traffic that the students are using. Basically, will he be able to see my network traffic? More importantly, will he be able to trace it to my computer or its MAC address? I am connecting over Wi-Fi, not ethernet.

  • 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!

  • Administrator view ALL mapped drives

    - by kskid19
    In my understanding of security, an administrator should be able to view all connections to and from a computer - just as they can view all processes/owner, network connections/owning process. However, Windows 8 seems to have disabled this. As administrator running an elevated in Win Vista+ when you run net use you get back all drives mapped, listed as unavailable. In Windows 8, the same command run from an elevated prompt returns "There are no entries in the list". The behavior is identical for powershell Get-WmiObject Win32_LogonSessionMappedDisk. A workaround for persistent mappings is to run Get-ChildItem Registry::HKU*\Network*. This does not include temporary mappings (in my particular example it was created through explorer on an administrator account and I did not select "Reconnect at sign-in") Is there a direct/simple way for Administrator to view connections of any user (short of a script that runs under each user context)? I have read Some Programs Cannot Access Network Locations When UAC Is Enabled but I do not think it particularly applies. I have seen this answer, but it still does not address non-persistent drives How can I tell what network drives users have mapped?

  • 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.

  • Network Load Balancing and AnyCast Routing

    - by user126917
    Hi All can anyone advise on problems with the following? I am planning on installing the following setup on my estate: I have 2 sites that both have a large amount of users. Goals are to keep things simple for the users and to have automatic failover above the database level. Our Database will exist at the primary site and be async mirrored to the secondary site with manual failover procedures.The database generate sequential ID's so distributing it is not an option. I plan to site IIS boxes at both sites with all of the business logic on them and heavy operations. The connections to SQL will be lightweight and DB reads will be cached on IIS. On this layer I plan to use Windows network load balancing and have the same IP or IPs across all IIS boxes at both sites. This way there will be automatic failover and no single point of failure. Also users can have one web address regardless of which site they are in automatically be network load balanced to their local IIS. This is great but obviously our two sites are on different subnets and as this will be one IP address with most of our traffic we can't go broadcasting everything across the link between the sites. To solve this problem we plan to use AnyCast routing over our network layer to route the traffic to the most local box that is listening which will be defined by the network load balancing. Has anyone used this setup before? Can anyone think of any issues with this? Also some specifics I can't find anywhere at the moment. If my Windows box is assigned an IP and listening on that IP but network load balancing is not accepting specific traffic then will AnyCast route away from that? Also can I AnyCast on a socket level?

  • Folder Redirection won't load on Windows 7 Machine in Windows 2008 R2 Network

    - by leeand00
    Okay so redirected profiles don't load exactly, but the computer is joined to the network and it won't display any of the users files on their desktop that are in their redirected profile. I know this because we have a Terminal Server and when the user logs in there, her files appear. I checked the users' profile in Active Directory Users and Computers and compared it with a working users profile. When that didn't turn up any differences, I looked at her computer and found that on the Dial-in tab the Network Access Permission wasn't set to Control access through NPS Network Policy like it was on the other machines on the network; so I selected it, ran gpupdate /force on her machine and rebooted. This did not fix the issue. Is there anything else that could be preventing the redirected files on the users desktop from showing up when the user logs in?
