• 1080p HD TV + what is minimum spec pc required to stream HD movie files to it?

  - by rutherford

  I want to stream hi-def (non flash-based) movies from my future minimum spec pc to my network-ready HDTV. What I want to know is a) when streaming from a computer (local wifi network), is the computer's cpu/video/ram resources used to the same extent as it would be if playing back on the computers local screen? If not what are the differences? b) So with streaming hd content what is the minimum spec processor I should go for, if i) only one TV is acting as client ii) two TVs are simultaneous clients.

• Does anyone know of a inexpensive NAT router that has the ability to limit access to the Internet to

  - by Corey

  Does anyone know of a inexpensive NAT router that has the ability to limit access to the Internet to a specific MAC address? I know the Linksys routers have a MAC filtering feature, but it is the opposite of what I need. It allows you to block access to a specific MAC address. I need something that will block all, but allow an exception. I'm dealing with some VOIP issues in my company's network, and I think the answer is to have a separate router on the network for my PBX to use. I want to make sure that other nodes are not allowed to access the Internet via this second router.

• "The requested operation could not be completed due to a file system limitation" 3202

  - by user46529

  I backup SQL Server database and it fails BACKUP DATABASE dd TO DISK = '\backupServer\backups\dd.bak' WITH COMPRESSION, CHECKSUM, NOFORMAT, INIT , BlockSize = 65536 , BufferCount = 2200 , MaxTransferSize = 4194304 The backup size is 3TB and I have 6TB free space on bacup server. I am using backup parameters per SQLCAT whitepaper. Everything works ok when I backup to local HDD and it always fails when I backup to network share. After about 6 hours. Can't find why. Thank you. Yes. The backup over the network is fastest and saves me 3Tb of local disk space :) Thanks for pointing to the memory issue. I left 4Gb to OS and it worked!

• I need to make Windows 7 STOP disabling the wifi adapter when the wired LAN is connected

  - by Escobar Ceaser

  This is a Dell Latitude E6430. There is a setting in the bios to control this behavior and I have DISABLED it but it still happens. I am also running the latest bios. When I plug in a network cable the wifi adapter becomes disabled. I need it to stay enabled. What else could be making this happen? EDIT: The reason I need to do this is because with NETSH WLAN commands you can create a wifi hotspot by sharing the internet connection on the wired adapter and broadcasting a ssid on the virtual wifi nic. I do this all the time but it's not working on this laptop. I'm wondering if it's a network security thing where I am. I'm going to try from my hotel tonight and report back.

• IPv6 scope id issue with IE

  - by eych

  I have an ASP.NET website that works with Firefox because FF doesn't need the % in the scope-id to be encoded (%25). The website also works on the same machine using IE because I can leave out the scope-id. However, to access the website from another machine in the network, I need to add the scope-id to the IPv6 address. For some reason, using the scope-id doesn't allow an authentication cookie to be created, and the website keeps going back to the login page. Anyone using IE7+ to access an ASP.NET website on a network using IPv6 with an encoded %?

• have 2 exchange servers to communicate together!

  - by Data-Base

  we have our exchange server 2007 (10.10.2.11) at work with domain "dddddd.com" and ironport and it work just fine! we need to test some thing at work with Exchange 2010 !! so we came up with this idea: we created a locked network and install firewall (10.10.2.88) the locked network has it's own DC and Exchange servers! we used the domain "dddddd.loc" any way it will be deleted! IPs DC 10.0.0.1 EX 10.0.0.11 now the Exchange server up and running in the firewall (10.10.2.88) we opened the ports and forwarded it to the Exchange2010 (10.0.0.11) in our main DC we defined the zone dddddd.loc to the firewall and the MX records as well but when we test we get error now how to make it so that the 2010 will send email directly to the 2007 (we will not use it to more that that)? and the 2007 will send the email to 2010 if the email has the domain dddddd.loc ?

• Set up router to vpn into proxy server

  - by NKimber

  I have a small network with a single LinkSys router connected to broadband in US via Comcast. I have a VPN proxy server account that I can use with a standard Windows connection, allowing me to have a geographic IP fingerprint in Europe, this is useful for a number of purposes. I want to setup a 2nd router that automatically connects via VPN to this proxy service, so any hardware that is connected to router 2 looks as though it is originating network requests in Europe, and any hardware connected to my main router has normal Comcast traffic (all requests are originating from USA). My 2nd router is a LinkSys WRT54G2, I'm having trouble getting this configured. Question, is what I'm trying to do even feasible? Should the WRT54G2 be able to do this with native functionality? Would flashing it with DD-WRT allow me to achieve my objectives?

• New Servers Active Directory and Exchange

  - by user3164638

  I have 3 Dell PowerEdge server, each with 2 quad-core processors. I am going to bring this office out of the stone-age network (P2P, share files on a flash drive, emails through Google, etc) and set up Active Directory and Exchange 2013. Our needs are not that great at the moment - our staff consists of approximately 40 people, and our network may eventually be managed by an external company. We need only one domain for our emails (though we may serve emails for a few other partners domains as well). I was thinking of setting something up like this: Server 1: Primary DC. Active Directory and Exchange on separate virtual machines. Server 2: Redundant of server 1. Server 3: Shared resources, storage, backups, etc. How would you utilize 3 servers for an Active Directory / Exchange setup for a small/medium office? We do have plans to grow, so my solution must be scalable, though I'm not sure that I want to split permissions, though I'd consider it if that was something that could be changed on down the road.

• Mac Snow Leopard Server DNS

  - by panomedia

  I have a Tomcat-driven application on my Windows server that I am planning to move to a MacMiniServer. Before I do this, I want to fully test the transition for licensing purposes. I have a Fire drive setup with Snow Leopard Server and the base app runs just fine BUT I need to be able to resolve the URL to my domain and not localhost. So, I figured I would setup panomedia.net in the DNS Server and also create an A record to my internal network IP so www.panomedia.net would dish out the same thing as localhost. The problem is: The Tomcat web app starts up going through panomedia.local and not through www.panomedia.net and My main network preference panel is still looking at my Comcast DNS search providers even though I put my local IP address as the only DNS Server and Search provider. I need to test this via an actual domain name before I commit to a 400GB data move. Can anyone help?

• How do I know if I need a level 3 switch?

  - by eekmeter

  We currently have a flat network with a bunch of unmanaged switches. I would like to use VLANs to segregate certain users like guests and I would like to use 802.1x. However, I'm not sure if what I need is a level 3 or a level 2 switch. From what I understand a level 3 switch does routing between VLANs. I don't think I need this at the moment but as I said I'm not sure since this is all new to me. What else would a level 3 switch do for me? Our network is relatively small, less than a 100 users. What exactly does a level 3 switch do that I can't get with a level 2 switch? When would I need a level 3?

• Even distribution through a chain of resources

  - by ClosetGeek

  I'm working on an algorithm which routes tasks through a chain of distributed resources based on a hash (or random number). For example, say you have 10 gateways into a service which distribute tasks to 1000 handlers through 100 queues. 10,000 connected clients are expected to be connected to gateways at any given time (numbers are very general to keep it simple). Thats 10,000 clients 10 gateways (producers) 100 queues 1000 workers/handlers (consumers) The flow of each task is client-gateway-queue-worker Each client will have it's own hash/number which is used to route each task from the client to the same worker each time, with each task going through the same gateway and queue each time. Yet the algorithm handles distribution evenly, meaning each gateway, queue, and worker will have an even workload. My question is what exactly would this be called? Does such a thing already exist? This started off as a DHT, but I realized that DHTs can't do exactly what I need, so I started from scratch.

• What is a Dynamic way to Connect to a Virtual Machine's Webserver from its Host Machine? [closed]

  - by Jonnybojangles

  As a Web-Developer what is the most efficient (automated) way to connect to a Virtual Machine (VM) running a development webserver from it’s Host Machine (the machine running the VM) when you do not have control over the networks (home, Startbucks, work, etc) you are connected to? Currently I start my VM (a VirtualBox VM running CentOS), run ifconfig to determine the VM’s current IP. I then take that IP and map it my Host machine’s host file so that I can access the VM’s webserver from the Host. I feel that this is not an efficient way to connect to my VM’s webserver because each time I connect to a new network (a few times a day) I need to repeat the IP look up and host file update, and sometimes restart the VM's network service.

• How setup federated SQL data to display limited information to a Web server in the DMZ?

  - by Pcav

  I have a SQL server behind a firewall. I need to push some limited SQL 2005 information to a Web Server in the DMZ so that I do not have to let database queries come all the way into the database server on our internal network. I want to push a small amount of dynamic data to a Web server in the DMZ and lock it down so that our hosted website does not need to come into the internal network for information; I want to put a server in the DMZ that will be the only connection allowed to the SQL database. This DMZ server will be the only server that can have any sort of connection to the back-end database so the hosting provider just pull the data from our server in the DMZ...

• Snow Leopard Windows 7 File sharing issue

  - by nsiggel

  Hello, wondering if anyone might have any suggestions on how to fix this issue in file sharing between Snow Leopard and Windows 7. On my home network, I have a system running windows 7 which acts as a file server: \WINDOWS7-A\SHARE I also have an IMac which can access the file share most of the time.... however now comes the problem, as soon as I introduce my Windows 7 Laptop and copy files over from it onto the file server (\Windows7-A), the file server become no longer accessible from the Snow Leopard machine... I assume this somehow has to do with elevated security on the network share having been negotiated between the 2 Windows 7 machines which is no longer allowing the Mac to see the Windows machines... but not sure how to disable this, as the only way I can restore communication between the mac and the Windows 7 machine is to restart it... less than ideal... Any suggestions would be welcome.

• Macbook not connecting to WIFI

  - by Model Reject

  I have been having this problem all week. My Macbook aluminium can't see my wifi network.

• Template loading slowness on VPN

  - by Mesut

  Hi All We have got lots of Word templates on our network. They are perfectly working on local area network. However, if users try to create a new word document from a template when they are connected to VPN outside of the office, it takes nearly 20 minutes to create a word file which is not reasonable at all. Have you guys ever come across with this type of issue? if yes, any suggestion or help would be appreciated. Many Thanks from now on. Best Regards Mesut

• pfSense router gives DNS rebinding warning when accessing subdomains

  - by Richard Maddis

  I have just set up a router running pfSense on our network and forwarded the appropriate ports. I have a small web server running in my network, and a domain name pointing to our (WAN) IP. When accessing that domain name, everything works fine. However, when accessing a subdomain of the domain name, pfSense will give a DNS rebinding warning. This did not happen back when I used a DD-WRT router. What is the proper way to fix this? The DNS records for the subdomain also point to the same address (I use a virtual server to differentiate the subdomains.)

• ADF Hands on Training &ndash; Prerequisites for 22nd March 2011

  - by Grant Ronald

  For those of you coming to the ADF Hands on training on the 22nd March in London, there was a link to the prerequisites.  Unfortunately, in a reshuffle of content on OTN, this page was removed.  So, over the next day or so I’m hoping to the pull together the relevant information into this blog post.  So keep checking back! Firstly, you need to being your laptop with you to do the hands on exercises.  No laptop, no hands on. Recommended 2GB RAM running Microsoft Windows XP SP2, 2003 Server SP2, Vista (32 bit only), Windows 7 or Linux or Mac 2GHz Processor (less will be acceptable but slower) Mozilla Firefox 2.0 or higher, Internet Explorer 7 or higher, Safari 3.0 and higher, Google Chrome 1.0 or higher Winzip or other extracting software Adobe Acrobat reader Flash (if you want to see dynamic graphs in your application) As for software, you will need have installed JDeveloper 11g.  The hands on instructions are based on 11.1.1.2 (or is it 11.1.1.3)! anyway, either of those or 11.1.1.4 would be required. You also need an Oracle database on your machine and access to the HR schema (which should be unlocked).  Don’t expect to have access to a network and VPN to a database. A simple test, unplug your laptop from your corporate network, run up JDev  and select File –> New –> Database connection and make sure you can connect to HR database and see the Emp/Dept etc tables.  If you can do that, you should be good to go. I would strongly recommend ensuring you have this in place before you arrive on Tuesday. Look forward to seeing you there.

• what do you use for storage discovery / storage management?

  - by lysdexic

  I am looking for some ideas on what would be the best way to discover and manage network storage. Discovery: Any good tools that will scan hosts and storage devices and report back their findings? Maybe using SNMP or WMI? Management: I'm currently looking at Storage Manager by Solar Winds, but it is a bit pricey. Any good open source projects like this? Just looking for ideas of how to get better visibility into the storage infrastructure on this network. It includes a HP Lefthand Iscsi san and EC VNX san. As well as individual hosts with local storage. Thanks for reading and thanks for any input.

• Updating shared files across computers

  - by murgatroid99

  I have a file server running Windows Server 2008 and a couple of laptops running Windows 7 on a network. There are a large number of files that all users will need access to. My plan is to have the files on both the server and the laptops because the users will need to access the files in places with no Internet access. I also want any changes made to the files on any of the laptops to propagate to the server and then propagate to the other laptops whenever they connect to the network. Should I do this with a scheduled batch script with a few xcopy commands or is there a better way to do it?

• Cross-platform centralized desktop password manager

  - by Dave

  I have been using KeePass as a desktop password manager on Windows for many years. Love it! However, I am now needing to work on different platforms much of my day (Windows 7, Windows XP, Mac OS X, Ubuntu, and OpenSUSE.) I'm looking for a password manager I can share across all these platforms. My ideal solution would: Run natively (not in a virtual machine) on all platforms. Store the "official" copy of the password data on a local network so I can get to it from any and all machines. It is OK if it locks (or becomes read-only) when one client is accessing it. Keep a local cached copy (read-only is fine) so I can still get to my passwords when disconnected from the network. Does any such beast exist?

• Port forwarding using IP Tables

  - by Darider

  I have a server with a LAN facing address of 192.168.5.100 (eth0) and another LAN facing address of 192.168.6.6 (eth1). On this server I have a Virtualbox instance of fedora running an apache webserver (on port 8080) with a bridged interface to eth1 on the host server with address of 192.168.6.7 Users on the 192.168.6.x network can access the Webserver on the Vbox instance (192.168.6.7) with no problems. My question is what kind of iptables entries or commands should be made/executed so as to allow for users on the 192.168.5.x network to access the webserver on the vbox instance. (I'm hoping their url can be something like: http://192.168.5.100:8080)

• Multi-machine backup solutions

  - by Paul

  I have a growing number of PCs and laptops in my home that need a backup solution. My question is 2 fold: Most commercial backup vendors appear to license by the machine, are there any products that give a license that can be used on all your machines, without a per machine cost? An alternative is to have a centrally controlled back up strategy controlled from a single PC with an attached hard drive that can back up other machines on the network. What backup software is suitable for this approach? Will this software be windows/Linux interoperable? I've searched for duplicate questions but don't see anything that addresses the multi machine/cost issue. OSs in network will be Windows (XP, Vista, 7) and Linux variants. Not pattern to when machines will be switched on.
