  • C# XML export for Excel table using XmlDocument

    - by Mark
    I am trying to write the following into an XML document: <head> <xml> <x:ExcelWorkbook> <x:ExcelWorksheets> <x:ExcelWorksheet> other code here </x:ExcelWorksheet> </x:ExcelWorksheets> </x:ExcelWorkbook> </xml> </head> However, if I use the following code, it strips out the 'x:'. System.Xml.XmlDocument document = new System.Xml.XmlDocument(); System.Xml.XmlElement htmlNode = document.CreateElement("html"); htmlNode.SetAttribute("xmlns:o", "urn:schemas-microsoft-com:office:office"); htmlNode.SetAttribute("xmlns:x", "urn:schemas-microsoft-com:office:excel"); htmlNode.SetAttribute("xmlns", "http://www.w3.org/TR/REC-html40"); document.AppendChild(htmlNode); System.Xml.XmlElement headNode = document.CreateElement("head"); htmlNode.AppendChild(headNode); headNode.AppendChild( document.CreateElement("xml")).AppendChild( document.CreateElement("x:ExcelWorkbook"))).AppendChild( document.CreateElement("x:ExcelWorksheets")).AppendChild( document.CreateElement("x:ExcelWorksheet")).InnerText="other code here"; How can I stop this from happening? Thanks!

  • Enterprise integration of disparate systems

    - by Chris Latta
    We're about to embark on a fairly large integration effort to kill off a bunch of Access and Sql Server databases and get everything into one coherent enterprise system. There are also a number of other systems (accounting, CRM, payroll, MS Exchange) that hold critical data that we need to integrate (use for data validation in other systems), report on and otherwise expose. It is likely that some of these systems will change in the next few years, so we need to isolate our systems to be ready for change. Ideally we would be able to expose our forms in a consistent manner across as many of our our systems as possible without having to re-develop them for each system. We are currently targeting SharePoint (2007 and soon 2010), Office (2007 and soon 2010 - Word, Excel, PowerPoint and Outlook), Reporting Services, .Net console applications, .Net Windows applications, shell extensions, and with the possibility of exposing some functionality on mobile devices (BlackBerries currently, maybe iPhones later) and via our website. We're moving development to Visual Studio 2010 (from 2005) ahead of migrating to SharePoint 2010 and Office 2010. Given that most of our development is presently targeted to the .Net framework (mostly in C#) it seems logical to stick with this unless there is some compelling reason to switch frameworks/platform for some aspects. We're thinking of your standard Database-Data Integration layer-Business Objects Layer-Web Services (or REST) layer-Client Application plus doing our own client application with WPF (or something else?) forms that can also be exposed in the MS systems (SharePoint, Office, Windows). So, we don't want much, just everything :) Basically we need to isolate ourselves from database and systems changes, create an API that can be used throughout our systems and then make this functionality available in our client applications. I'm very keen to get pointers from anyone who has tips on how to pull this off. Should we look at the Enterprise Library as a place to start? Is REST with ASP.Net MVC2 a better solution than Web Services for a system like this? Will WPF deliver forms re-use or is there something better?

  • How to access a web service behind a NAT?

    - by jr
    We have a product we are deploying to some small businesses. It is basically a RESTful API over SSL using Tomcat. This is installed on the server in the small business and is accessed via an iPhone or other device portable device. So, the devices connecting to the server could come from any number of IP addresses. The problem comes with the installation. When we install this service, it seems to always become a problem when doing port forwarding so the outside world can gain access to tomcat. It seems most time the owner doesn't know router password, etc, etc. I am trying to research other ways we can accomplish this. I've come up with the following and would like to hear other thoughts on the topic. Setup a SSH tunnel from each client office to a central server. Basically the remote devices would connect to that central server on a port and that traffic would be tunneled back to Tomcat in the office. Seems kind of redundant to have SSH and then SSL, but really no other way to accomplish it since end-to-end I need SSL (from device to office). Not sure of performance implications here, but I know it would work. Would need to monitor the tunnel and bring it back up if it goes done, would need to handle SSH key exchanges, etc. Setup uPNP to try and configure the hole for me. Would likely work most of the time, but uPNP isn't guaranteed to be turned on. May be a good next step. Come up with some type of NAT transversal scheme. I'm just not familiar with these and uncertain of how they exactly work. We have access to a centralized server which is required for the authentication if that makes it any easier. What else should I be looking at to get this accomplished?

  • How to do a partial database backup and restore?

    - by Workshop Alex
    Simple problem. I'm working on a single SQL Server database which is shared between several offices. Each office has their own schema inside this database, thus dividing the database in logical pieces. (Plus one schema that is shared between multiple offices.) The database is stored on a dedicated server and we use a single database to keep the backup/restore procedure easier. The problem, however, is that the Accounting Office might be modifying a lot of data and then the Secretary Office makes a mistake which requires restoration of a backup. Unfortunately, restoring the backup means that Accounting will lose their recently added data. So, the alternative solution is by restoring the backup into a new database, remove the data from the old accounting schema and move the data for accounting only from the backup top the original database. This is the current solution and it's time-consuming and error-prone. So, is there a way to make backups of a single schema, possibly through code? And then to restore just that schema, probably through code too?

  • How to conduct an interview for a development position remotely?

    - by sharptooth
    Usually we run interviews in office. We have a room with a table, the interviewee and one or two interviewers sit at the table, interviewers ask questions, often accompanied with code snippets on paper, the interviewee (hopefully) answers them, writes code snippets to illustrate his point. Usually it's something like an interviewer writes about five lines of C++ code and asks some specific question - quite a little code. Now we need to do the same remotely. We will be in our office and the interviewee will be far away - we are asked to help hire a person for another office located abroad. Of course we can use some technology for voice calls, but I'm afraid it's the most we can count on. I see a whole set of obstacles here: how to write illustration code snippets and exchange them efficiently? what to do to compensate for the fact that we're not native English speakers and the interviewees might or might be not native English speakers (I'm afraid this can make conversation significantly harder)? Are there any best practices for this situation? How could we address the obstacles listed? What other things should we consider to run the interview most efficiently?

  • Auto load balancing two node Cluster Hyper-v 2008 R2 enterprise?

    - by Kristofer O
    My setup is a 2 node cluster with 72GB ram each and a ~10TB MD3000i Iscsi SAN. I have about 30VMs running I keep about 15 on either server. I do a live migration to the other server if I need to run updates or whatever... Either one of the servers is able of running all VM if needed, but the cpu is pretty high. Here's my issues. I know Hyper-v has a limit of a single Live-migration at a time. But Why doesn't it queue them up to move one at a time? If I multi select I don't get the option to live migrate a one at a time. OR if I'm in the process of Migrating one it will give me an error that it's currently migrating a VM... Is there a button I missed that will tell a Node that it needs to migrate all the VMs elsewhere? Another question, does anyone know whats the best way to load balance VMs based on CPU and/or network utilzation. I have some VMs that don't do much. and some that trash the CPU or network. I'd like to balance it out on both servers if at all possible. and Is there any way to automate it? last question... If I overcommit my Cluster is there a way to tell the cluster that I want certian VMs the be running and to savestate other VMs based on availible system resources? Say when my one node blue screens and the other node begins starting the VMs up. I want the unimportant ones to shutdown or savestate so the important ones can stay running or come back online. Thanks just for reading all that. Any help would be great.

  • Apache mod_rewrite and mod_vhost_alias Virtual Hosts and %1

    - by Matt Wall
    I have put the main bits of my httpd.conf down below. I am using %1 to get the host field so I can dynamically add vhosts by just creating dns/folders. One problem is I need to reference this: HttpStreamingLiveEventPath "D:/FMSApps/%1" HttpStreamingContentPath "D:/FMSApps/%1" In Apache when I try say to do this: http://test.domain.com/hds-vod/myfile.mp4.f4m it sees the %1 in the logs, and fails. Apache gives me this: [error] mod_jithttp [403]: No access to D:/Content/%1/DefaultContent/eve.mp4 What I'm looking for is the D:/Content/%1/DefaultContent/eve.mp4 to become D:/Content/test/DefaultContent/eve.mp4 Anyone have any useful resources / hints etc. to help me?

  • How do you monitor SSD wear in Windows when the drives are presented as 'generic' devices?

    - by MikeyB
    Under Linux, we can monitor SSD wear fairly easily with smartmontools whether the drive is presented as a normal block device or a generic device (which happens when the drive has been hardware RAIDed by certain controllers such as the one on the IBM HS22). How can we do the equivalent under Windows? Does anyone actually use smartmontools? Or are there other packages out there? The problem is that SCSI Generic devices just don't show up in Windows. If the drives aren't RAIDed we can see them fine. How I'd do it in Linux: sles11-live:~ # lsscsi -g [1:0:0:0] disk SMART USB-IBM 8989 /dev/sda /dev/sg0 [2:0:0:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg1 [2:0:1:0] disk ATA MTFDDAK256MAR-1K MA44 - /dev/sg2 [2:1:8:0] disk LSILOGIC Logical Volume 3000 /dev/sdb /dev/sg3 sles11-live:~ # smartctl -l ssd /dev/sg1 smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Device Statistics (GP Log 0x04) Page Offset Size Value Description 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 26~ Percentage Used Endurance Indicator |_ ~ normalized value sles11-live:~ # smartctl -l ssd /dev/sg2 smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32.49-0.3-default] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net Device Statistics (GP Log 0x04) Page Offset Size Value Description 7 ===== = = == Solid State Device Statistics (rev 1) == 7 0x008 1 3~ Percentage Used Endurance Indicator |_ ~ normalized value

  • MSDTC - Communication with the underlying transaction manager has failed (Firewall open, MSDTC network access on)

    - by SocialAddict
    I'm having problems with my ASP.NET web forms system. It worked on our test server but now we are putting it live one of the servers is within a DMZ and the SQL server is outside of that (on our network still though - although a different subnet) I have open up the firewall completely between these two boxes to see if that was the issue and it still gives the error message "Communication with the underlying transaction manager has failed" whenever we try and use the "TransactionScope". We can access the data for retrieval it's just transactions that break it. We have also used msdtc ping to test the connection and with the amendments on the firewall that pings successfully, but the same error occurs! How do i resolve this error? Any help would be great as we have a system to go live today. Panic :) Edit: I have created a more straightforward test page with a transaction as below and this works fine. Could a nested transaction cause this kind of error and if so why would this only cause an issue when using a live box in a dmz with a firewall? AuditRepository auditRepository = new AuditRepository(); try { using (TransactionScope scope = new TransactionScope()) { auditRepository.Add(DateTime.Now, 1, "TEST-TRANSACTIONS#1", 1); auditRepository.Save(); auditRepository.Add(DateTime.Now, 1, "TEST-TRANSACTIONS#2", 1); auditRepository.Save(); scope.Complete(); } } catch (Exception ex) { Response.Write("Test Error For Transaction: " + ex.Message + "<br />" + ex.StackTrace); }

  • Permission / owner issue with pushing to git when editing directly from repo?

    - by Susan
    I have a web interface for deploying scripts from our repo at Github to our live server. The web interface just triggers a bash script with some git commands. If I make changes locally, push to repo, then run the bash script to pull from repo to live it works fine. However, if I make changes directly in the repo (via Github's web interface), I'm running into fast-forward / lock issues. These are the steps I'm taking: Make a change on a file at Github repo Run a bash script (as apache) via web from live server that attempts a git push / pull. Get these problems: PUSH To [email protected]:name/name.git ! [rejected] master - master (non-fast-forward) error: failed to push some refs to '[email protected]:name/name.git' To prevent you from losing history, non-fast-forward updates were rejected Merge the remote changes before pushing again. See the 'Note about fast-forwards' section of 'git push --help' for details. PULL From github.com:name/name branch master - FETCH_HEAD error: unable to unlink old 'includes/footer.inc' (Permission denied) Updating 8f6d922..d1eba9d Updating 8f6d922..d1eba9d SSH in as root, attempt a push / pull and it works fine. Ideas on why would this method not work from apache?

  • Asus MyCinema U3100mini Choppy

    - by dsimcha
    I'm running an Asus MyCinema U3100mini ATSC on Windows 7 64-bit. When I play live TV in Windows Media Center, it's very choppy and uses 500+ MB of RAM, I'm guessing due to the hard drive buffering functionality. Is there any way to disable the live TV pause buffer completely? If not, can anyone recommend alternative software that: Works with the MyCinema. Is lightweight and not horribly bloated with features I'll never use like Windows Media Center is. Edits: This is a dual boot system. I've discovered that the tuner actually works fine on XP. It also works fine on my other computer, which has slower hardware and also runs Windows 7 64-bit. The problem actually seems to be with playback at large screen sizes, not with hard drive buffering. Everything works fine below a certain window size and fails for large windows or full screens. Also, the same thing seems to happen whether playing live or recorded TV. As far as the obvious stuff goes, I have the latest video drivers from ATI for my Radeon x1050.

  • Why do I have to log into hotmail twice?

    - by Tony Lee
    I just recently noticed I have to attempt a login into hotmail twice before it succeeds. Although I'm using Google Chrome (3.0.195.21), the symptoms are well described in a Mozilla thread. In short, I'm told: The e-mail address or password is incorrect. Please try again. The thread on mozilla's site that supposed to describe the latest details (and the 1st hit on google when I search for "hotmail login twice") requires an account to read so I'm hoping someone here has a good synopsis of what the cause is. I normally start at hotmail.com, which redirects to login.live.com/.... I can login by starting at mail.live.com, using IE8 or attempting a 2nd login. Oddly, if I start at login.live.com Chrome tells me there is a redirect loop. Does anyone know or have a public link to the root cause of the double login? (it is a hotmail account I'm login into) EDIT - Caused by my 'restricting how 3rd parties can use cookies'. If I allow all cookies, it works first time.

  • Creating Custom ISO Images

    - by ericl42
    I am working on creating some custom ISO images using primarily Fedora and CentOS. I want the image to be a bootable live CD with some specific files on it. I also want it to have the option to be able to be downloaded to the hard drive. I've read some various articles but want to get a few more opinions since I've never done this before. Currently I'm trying 2 different methods. Install Fedora with the configuration exactly how I want it and then run the livecd-tools program to pull everything I currently have to an ISO. I haven't got this to work yet but I do see a few issues with it. Such as the default passwords I had to put in. Run a Fedora live CD and install a few things I want on it and then copy the image of it. I believe this would work better since it has more of a live cd feel. However I"m not 100% sure how I should go about pulling the current image to my own ISO. I know some people have said to use mkisofs and a few other programs but any advice would be greatly appreciated.

  • RPC Server Unavailable on Hyper-V cluster when moving resources after the host adapter has failed

    - by Doug Luxem
    On a Windows 2008 R2 SP1 cluster running Hyper-V, a lost network connectivity on the primary host interface. The interface was rapidly flapping up and down, and this was later determined to be caused by a faulty switch port. As this was a clustered server, the host interface was not fault tolerant (seeing as how the whole server was fault tolerant), so connectivity to the host was going up and down. The Hyper-V guests were completely unaffected by the network outage as they used a dedicated trunk on the server separate from the host interface. Additionally, dedicated interfaces for the cluster and live migration networks were fine. In order to diagnose the server, I tried to move all resources (Hyper-V Guests) to other nodes through Failover Cluster Manager. These moves failed with an error RPC Server Unavailable. The only way to move resources was by shutting down the guests, stopping the cluster service on the Node A, allowing other nodes to take ownership of the resources, and restarting the guests. A few other notes: All nodes have Client for MS Networks and File & Printer Sharing enabled on the Cluster and LM networks. Node A was accessible over cluster and LM networks from other nodes (these are private, cluster-only networks); pingable, CIFs, etc. Accessing \\NODEA is done over the Host adapters, as you would expect in this case and is the reason for the RPC Server Unavailable error with that adapter being down. My questions here are - Is there a way to still use Live Migration in a failure scenario such as this to prevent shutting down the Hyper-V guests? How can the network be reconfigured in the future so that the cluster service attempts to use the cluster and/or live migration networks to issue the RPC requests?

  • How does Google geo location service work?

    - by heaosax
    I dont use google maps much, but I was using it today and I clicked the "Show my location" button for the first time, then firefox asked for permission and I clicked "share my location", google maps showed my location pretty accurate. But, how does this system really works? I mean how can google know where I live? I am connecting to the internet with a VPN, so my "public IP" is not from my country, but from sweden, also I use linux and I change the mac of my wireless device, but google still show my location. I know I can disable this feature setting firefox about:config geo.enabled to false, but I am curious about how google can know where I live even when I dont have a real mac address and my IP is not from my real country. Basically I'd like to know if this feature works only because of code that exists in chrome and firefox (which spies my system)? I am worried about anyone knowing where I live, I mean... where is my privacy? Part of the fun about the internet is remaining anonymous.

  • Issues with returned mail sent to web-based email domains

    - by Beeder
    My company is having issues with returned mail that we send out to external domains. A few weeks ago we replaced a firewall and changed ISP providers and began subsequently having issues RECEIVING emails from external sources because we hadn't updated our new IPs in the DNS records. After making the necessary configuration changes and setting up SMTP forwarding over port 25 to our mail server, everything was working fine up until a few days ago when we started having mail sent out returned to us. We aren't having any trouble communicating internally (to recipients on our domain) but it seems we're having trouble with outbound messages to web-based email recipients. (@hotmail, @live, @yahoo, @gmail...etc) Currently we are running Server 2003 SP2 and exchange 2003. I'm very unfamiliar with configuring Exchange and could really use some help in narrowing down the possibilities. I did some research and am becoming suspicious of Sender ID being the culprit due to our recent IP address change and the likelihood that Sender ID is identifying us as a fake domain. Am I going in entirely the wrong direction? Any input or guidance would be infinitely appreciated. This is the message that is returned when an outbound message fails...this particular one was sent to my @live.com account for testing purposes... Your message did not reach some or all of the intended recipients. The following recipient(s) could not be reached: [email protected] on 5/17/2012 3:02 PM There was a SMTP communication problem with the recipient's email server. Please contact your system administrator. Unfortunately, messages from xx.x.xx.x weren't sent. Please contact your Internet service provider since part of their network is on our block list. I tried a reverse DNS lookup and found that we are set up as a Forward-confirmed reverse DNS. So do I just need to contact my ISP and have them correct their DNS records or is this something I can solve on our end??

  • Windows Server 2012 Branchcache vs. DFS-R

    - by TheCleaner
    Warning, subjective question ahead! But hopefully a good one that won't get closed. SCENARIO: I have a branch office that currently has no on-premise server. They access everything including a DC across a 12Mbps WAN link (MPLS). The link isn't saturated, averaging around 20% utilization. The circuit is very stable and has a high SLA and excellent uptime. However, large file transfers (mainly reads, not writes) from the file server across the WAN can be slow. We don't currently utilize DFS. RESEARCH DONE: I'm aware of WAN acceleration, using either dedicated hardware (Riverbed) or a dedicated software VM (Silver Peak) for example. But the pricing is outside of our current budget and the need isn't quite there yet from our perspective (since the issue is mainly in a "pull" scenario not necessarily push/pull). I'm mainly looking at deploying a Windows server at this branch office and either utilizing DFS-R or BranchCache. Looking at a table comparison and assuming we are looking at a "hosted branchcache server" and not simply distributed: It would appear there are benefits to both, even if both are "hosted" on a server. QUESTIONS I ACTUALLY HAVE: In what scenarios do each of these techs shine and where do you choose one over the other? Looking at a hosted Branchcache server, can you set "pre-fetching" of certain folders/files on the central file server so that they are immediately accessible locally at the branch? Do you have to do this on a schedule (if it is possible)? Looking at DFS-R my concern (and apparently solved with 3rd party apps) is file locking and making sure the file gets updated properly during a write operation (ie, making sure if both copies are accessed and both are written to, which file takes precedence and what happens to the changes?). Ideal it would seem would be to lock any alternate replicas of the data, but is it really that big of an issue? Does Branchcache lock the central file for editing? Does branchcache only transmit the deltas back to the central file of what has changed? Would either technology be ill advised if the branch office server was going to be utilized as a domain controller as well?

  • Outlook 2007 unable to connect to exchange server

    - by mattwarren
    I came into the office a week ago and outlook has refused to connect ever since, it just says "Disconnected" in the bottom right-hand corner. I've tried restarting it, rebooting Windows etc. I'm the only one if our office who is having this problem, so it's not a general problem with the server. Things I've tried Pinging the server via IP address and host name, both work fine Connecting via OWA, this works using the same machine name Connecting to Exchange via HTTP ("Outlook Anywhere") doesn't work None of the suggestions in this question helped, http://serverfault.com/questions/21755/can-ping-exchange-server-cant-connect-outlook-to-it Disabling Windows firewall on my laptop also has no effect. There are no items in the event viewer that indicate that anything it up. Also no permissions have changed on the server since when it worked. What else can I do to diagnose this, any suggestions?

  • Issue with Sharepoint 2010 application page

  • ssh tunnel error "ssh_exchange_identification: Connection closed by remote host"

    - by Jacob Ewing
    I'm trying to use an ssh tunnel from my office machine to my home machine, and get an error when I try to use it. What I'm doing is starting one shell like so: ssh -gL 12345:my.home.domain:22 my.home.domain This is giving me a proper shell, no problem. What I normally do then is ssh to my home machine through this office machine, like so: ssh -p 12345 127.0.0.1 This has always worked for me, until last week, when I set up a new system on my home machine (switching from Ubuntu to Debian). Now I get an error. I can still open up my initial ssh connection, but when I try to use that tunnel, I get (on the office machine) this error: ssh_exchange_identification: Connection closed by remote host Also, when that happens, the open shell that I have the tunnelling set up through gets this line spat out at it: channel 3: open failed: connect failed: Connection timed out At which point, I'm at a loss. If any more info is needed, I'll be happy to post it. ============= further to that ============== After fiddling around further, I've found that I'm getting a different response from the server (my home machine that is) when I try to telnet in on the various ports. If I try: telnet my.home.domain 22 I get this back: Trying <my ip address>... Connected to <my domain>. Escape character is '^]'. SSH-2.0-OpenSSH_5.5p1 Debian-6+squeeze2 Which is what I would expect. After setting up the tunnel though, and then telnetting to that, I see this response: Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. ============== and further still ================== As per kbulgrien's suggestion, here is the output from the client machine with the -v option: ssh -vp 24600 127.0.0.1 OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to 127.0.0.1 [127.0.0.1] port 24600. debug1: Connection established. debug1: identity file /home/jacob/.ssh/id_rsa type -1 debug1: identity file /home/jacob/.ssh/id_rsa-cert type -1 debug1: identity file /home/jacob/.ssh/id_dsa type -1 debug1: identity file /home/jacob/.ssh/id_dsa-cert type -1 debug1: identity file /home/jacob/.ssh/id_ecdsa type -1 debug1: identity file /home/jacob/.ssh/id_ecdsa-cert type -1 ssh_exchange_identification: Connection closed by remote host

  • Need help diagnosing network performance issues

    - by tokes
    I am currently working in a developing country as a system analyst for a government department. My area of expertise is software projects, but I've come across a few issues with the network setup in my office. (Unfortunately, being a developing country, there's not a lot of professional help available for this sort of thing.) Most recently, I am trying to diagnose a problem with slowness on the network. Our office is connected to the internet via an ADSL wireless modem/router (called Router). The modem is connected via ethernet to a switch (called Switch). The modem also acts as a wireless access point (called Wireless1), though because it is in a room at the end of the floor, it's range is limited. There are ethernet ports installed around the office. The cables of these all lead back to the same switch. In closer vicinity to the bulk of the client computers, there is another wireless router that acts as an access point for those clients (called Wireless2). That router is connected via ethernet to a wall port, and therefore to Switch. There is also a Windows server which acts as a DNS server (called DNSBox) which is located in the same room and is connected directly to Switch. ---Internet----------| Router/Wireless1 192.168.10.1 ---------------| |----|=========| DNSBox | |-------------------- 192.168.10.4 --------------------| Switch |---Other clients---- | |-------------------- |----|=========| Wireless2 ------------------| 192.168.10.198 One final thing to mention about the network setup. All clients are configured with manual IP addresses. Their router/gateway is set to the IP address of Router, and their DNS server is set to the IP address of DNSBox (with a secondary IP set to an external IP - that of our ISP's DNS server). Here are the symptoms we are experiencing: Clients connected to Wireless2 AP experience slow and unstable connections to the internet. (Slow here is defined as speeds of ~1KB/s, though ping response times seem to be as normal.) Clients connected via ethernet to Switch also experience the same slowness. Clients connected to Wireless1 AP (i.e. connecting via wireless directly to the ADSL modem) experience normal connections to the internet. Clients connected via ethernet to Router (i.e. connecting via ethernet directly to the ADSL modem) also experience normal connections to the internet. I also tried to gauge the connection performance between two machines on the network via ethernet: A file transfer between two clients who were both directly connected to Switch was the fastest; A file transfer between one client directly connected to Switch, and one client directly connected to Router (which is directly connected to Switch) performed much slower; A file transfer between two clients directly connected to Router also performed slowly. Things I have attempted to diagnose the problem: Restarted Switch -- no change. We tried unplugging ethernet jacks from Switch 4 at a time and testing the internet connection. The thought here was that perhaps a client on the network has contracted a virus, and is possibly spamming the network with traffic? (Not very technical, I know.) Unfortunately we couldn't get any significant increases in performance using this method. There were a couple of times when it seemed to be better, but then the connection speed quickly dropped back to slow/dead pace. I didn't want to unplug all jacks from Switch because I was concerned that users might be affected or that I would re-plug in the jacks incorrectly (should I even be worried about that? a port is a port on a switch, right?) I tried swapping the ethernet cable used to connect Router to Switch -- no change in performance. I tried swapping the port used on Switch for Router -- no change in performance. Anyone got any ideas on what this could be? Should I be mentioning specific brand names/models of the hardware used? Virii outbreaks are common in this country/office -- what could I be doing to figure out if a virus is at fault? If it is a virus, it doesn't seem to be generating a lot of traffic to/from the internet, because a) I can still get a good speed if I am directly connected to Router / Wireless1 and b) our ISP data usage has not risen suspiciously. Thanks for your help! Update #1 Here are the specs of some of the hardware: Switch is an Edimax ES3132RL 32-Port 10/100 Rackmount Switch Router is a D-Link DSL-G604T Update #2 I just tried unplugging everything except a laptop and Router from Switch. Speeds are still slow. I guess that means that Router / Switch are not being flooded? It seems more and more likely that the cause is something to do with the interaction between Router and Switch. However, I still can't find any useful resources on setting the LAN speed for either (and I'm not well-versed in these advanced networking configurations).

  • IPSec VPN's being dropped by router and will not re-establish

    - by David Gard
    We have 3 sites, with our two remote sites connection to head office via LAN-to-LAN VPN's. All 3 sites use DrayTek 2900's with firware version v3.3.1.1_RC2 (this is a release candidate that DrayTek suggested I try, but sadly it made no difference). The only way to re-establish the VPN's once they have been dropped is to restart the router. Head office is set to dial out to both sites, with both the 'Always on' and 'Enable PING to keep alive' (pinging a server in the remote offices) options ticked. However, at random intervals the VPN's drop, logging IKE_RELEASE VPN : Dial-out Profile Index = 7, Name = Shepton (for one connection, and '6' & 'Wincanton' for the other connection). I first tried swapping the router with one at another site, and then had all three replaced, but that failed to solve the problem. Is anyone aware of anything that could cause the VPN's to drop randomly like this? Thanks.

  • Create firewall "profiles" for Windows 7

    - by Samantha
    Is there any way to configure a couple of firewall profiles in Windows 7? As I use mobile broadband on when traveling, I don't want virus scanner/windows updates etc running and chewing up my mobile data allocation. So would love to find a way to block everything except email ports and perhaps http. The kicker though is that when I'm back in the office, I want to just click a button to get my original firewall settings back. In the office I use WiFi and on the road tether to my android phone, also via WiFi, so can't restrict via network interface. Any ideas?
