  • Is it possible to "virtualize" an existing PC?

    - by pnongrata
    I'm running Ubuntu Desktop 12.04, and I was wondering if it was possible to somehow take my whole filesystem (everything under /) and create an ISO from it. Then, perhaps, use that ISO as the file system of a VBox VM (obviously, it would have to be Ubuntu, and probably 12.04). Basically, I've spent a lot of time configuring my development machine, but need to be able to work on it from whatever computer I happen to be at. VMs seem like the perfect solution. Thanks in advance!

  • How to find out where or if MYSQL5 logs are stored on a machine WHM/Cpanel

    - by moi
    I have a WHM/Cpanel re-seller hosting account on a virtual private server (Linux). I have root access to the machine via SSH I am trying to locate a file that contains information that will help me to determine which users have accessed what db and from which hosts. I would imagine this kind of data is stored in a log file somewhere. The MySQL page says: The general query log - Established client connections and statements received from clients See: http://dev.mysql.com/doc/refman/5.0/en/server-logs.html It also says: By default, all log files are created in the mysqld data directory. So, I am am NOT asking where are the general query log logs stored, (cos I expect I will get answers saying "it depends") Please help me work out: "How can go about finding out where MySQL general query log logs are stored on a linux machine" Couple of things i've already tried: I looked at /etc/my.cnf it was a tiny file that only contained the following info: [mysqld] skip-bdb skip-innodb set-variable = max_connections=500 safe-show-database ~ ~ I have looked in: /var/lib/mysql/ But I could not see any log-like file names in that directory. Any clues on this would be most welcome.

  • wget not working with domain on local machine

    - by user568829
    Basically - I have some PHP scripts that need to be run as cron jobs. Lets say the script needing to be run is: http://admin.somedomain.com/cron_jobs/get_stats If I run the script from the local machine it gives me a 404 Not Found error. So I entered the following into /etc/hosts XX.XX.XX.45 admin.somedomain.com Now wget works fine from the local machine to that domain. However when I restart Apache that domain no longer works. Here is the config for that site in /etc/apache2/sites-available NameVirtualHost XX.XX.XX.45:80 <VirtualHost XX.XX.XX.45:80> ServerName admin.somedomain.com DocumentRoot /var/www/admin.somedomain.com/ <Directory "/var/www/admin.somedomain.com"> allowoverride all Options Indexes order deny,allow allow from all </Directory> ErrorLog /var/log/apache2/admin.somedomain.com-error_log CustomLog /var/log/apache2/admin.somedomain.com-access_log combined </VirtualHost> It just goes to the default site config showing "It Works". If I take out that setting in /etc/hosts and restart apache the website at that domain works fine again. Can anyone point me in the right direction here? Thanks

  • access an IP restricted service from a dynamic IP (Broadband modem) on a windows machine

    - by Joel Alenchery
    Hi, I dont know if this is the correct place to ask this question but here goes .. (please note that I am pretty much a newbie in terms of networking and I work primarily on the windows platform) I have been working on accessing and consuming some web services in C#/ASP.Net, these web services that I consume are IP restricted. Currently they allow access only from my work network (we have a static ip set up through which all our internet requests are routed). Every now and then we have people who go out and about and are stuck with using a usb dongle based internet connection and hence are not able to now access these web services that they are working on. What I would like to do is to provide some way for these remote workers to access the IP restricted web services using the static ip at our office. For example when the remote worker tries to access a service say http://exampleService.com .. the request gets routed to some box at our office and then out to the actual service. That way the service always sees the static ip of the office and not the dynamic ip that the remote user is actually using. I have done a fair bit of googling and its difficult to search for it as most of the results come back for dynamic DNS which is not really what I am looking for. I have also looked at a couple of posts on here namely Accessing IP restricted server from dynamic IP which does provide some insight but the fellow seems to have access to the source that does the ip restriction and is able to change the restrictions. In my case i dont have that access. another one that looked interesting was Static IP for dynamic IP the first answer seems exactly what I need but I dont know how I would go about doing the same on a windows machine. any help would be really appreciated. (am sorry about being soo noob-ish) PS: Right now everyone is using RDC/LogMeIn to access an internet connected machine in the office to manually check the webservice and getting work done. Which is a very tedious process.

  • Connecting to server from remote machine

    - by Jannat Arora
    I wish to connect my machine to a server in some other city. For doing the same I am using the following command: mstsc -v ip_address_of_server remote desktop can't connect to remote computer for one of these reasons: 1) Remote access to server is not enabled. 2) Remote computer is turned off 3) Remote computer is not available on network. Make sure remote computer is turned on and connected to the network, and that remote access is enabled. As per previous posts I need to turn off my client computers firewall..which I have...but still it gives me the same message. Can someone please please help me out...so as to how i may resolve this?? I am really new to networking, etc. Also when i am pinging: ping ip_address_of server I am getting the following response: Reply from ip_address_of_server: destination host unreachable Also I did try on ubuntu with rdesktop...still its not been able to connect with it. Also i know there are other people who are able to connect their machines with the server remotely. So i guess its not working for me only. Also when I accessed the same machine through LAN I was able to do so.

  • can not connect to SQL running on amazon ec2 machine

    - by njj56
    I am using SQL managment studio 2008 running on an Amazon EC2 machine. I am unable to connect to the database in my asp.net application. The EC2 instance has been set to accept connections over the SQL port. I am also able to remote the machine as well as view websites hosted on the server. Listed below is part of the connection string relating to this instance. When the program is ran and this connection string is called, it returns tcp error 0 - no return response. it just times out. <add name="ProjectServer" connectionString="Data Source=*IP ADDRESS HERE*,1433;Initial Catalog=*Catalog Name*;User ID=IP-0A6ED514\Administrator;"/> I removed the ip and the catalog name for the example, but I am sure they are correct. The only thing that I could think may cause an error, is the differences in names between the user id and the server name - the server name is ip-0A6ED514\sharepoint but the user name is ip-0A6ED514\administrator when I log into the sql server manager on the EC2 instance. A password is not used. Not sure if I would need to leave in a blank string for password - also not sure if the difference between server name and user id to log in makes a difference. Any help is appreciated. Thank you. update - when this connection string is used with out the port, i get tcp provider error 40 - when the port is in there, i get error 0 edit- the sql server is using windows authentication - does this make a difference? Usually I always use SQL server authentication

  • Limiting bandwith on an Windows 7 machine

    - by Mihai Damian
    I need to limit the bandwidth on my Windows 7 x64 machine. In the past (on XP) I've been able to use NetLimiter for similar tasks. However for some reason I can't get it to work anymore. For lower limits the bandwidth tests are able to exceed the limit by 10-50%; higher limits seem to be ignored completely and the bandwidth tests report download speeds of over 10 times the speed I set. I'm using speedtest.net and some similar service from my ISP for these tests. Anyway, I don't necessarily need a program as complex as NetLimiter since I only need to throttle my machine's bandwidth, not a specific program's. In case you are wondering why in the world I'd want to cripple my Internet speed, there is a funny story behind this. Long story short, my modem gets random disconnects. Tech support comes in, says my Internet speed is abnormally high and I must be using some tools to somehow make it go faster than it's supposed to and this messes up my modem. I check the connection with another computer and it seems that my PC is the only one in my network that gets abnormal speeds. I reinstall my OS, speed looks normal at first, after I install the batch of 50 or so updates, it goes back to abnormally high speeds and the disconnect problems are not solved. Now I don't have a clue if the explanation the tech team gave me was just a strategy to lay the blame on someone else, but I was trying to give them the benefit of the doubt and see what happens if I really reduce my speed to their specification. Any help appreciated.

  • iis7 large worker process request queue creating process blocking aspnet.config & machine.config amended (bottleneck)

    - by scott_lotus
    ASP.net 2.0 app .net 2.0 framework IIS7 I am seeing a large queue of "requests" appear under the "worker process" option. State recorded appear to be Authenticate Request and Execute Request Handles more than anything else. I have amended aspnet.config in C:\Windows\Microsoft.NET\Framework64\v2.0.50727 (32 bit path and 64 bit path) to include: maxConcurrentRequestsPerCPU="50000" maxConcurrentThreadsPerCPU="0" requestQueueLimit="50000" I have amended machine.config in C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG (32 bit and 64 bit path) to include: autoConfig="true" maxIoThreads="100" maxWorkerThreads="100" minIoThreads="50" minWorkerThreads="50" minFreeThreads="176" minLocalRequestFreeThreads="152" Still i get the issue. The issue manifestes itself as a large number of processes in the Worker Process queue. Number of current connections to the website display 500 when this issue occurs. I dont think i have seen concurrent connections over 500 without this issue occurring. Web application slows as the request block. Refreshing the app pool resolves for a while (as expected) as the load is spread between the two pools. Application pool in question FIXED REQUEST have been set to refresh on 50000. Thank you for any help. Scott quick edit to say hmm, my develeopers are telling me the project was built with .net 3.5 framework. Looking at C:\Windows\Microsoft.NET\Framework64\v3.5 there does not appear to be a ASPNET.CONFIG or a MACHINE.CONFIG .... is there a 3.5 equivalent ? after a little searching apparenetly 3.5 uses the 2.0 framework files that 3.5 is missing. So back to the original question , where is my bottleneck ?

  • Thin client - cloud machine - to run via iPad, iPhone, most Androids etc

    - by Carl Lindberg
    I'm tired of having a laptop macbook that breaks down or having files that I need to sync via dropbox etc all the time via the machines to different OS installations. It sucks. I want a thin client where I can login on any machine - my iPhone, PC desktop, iPad etc to one running machine. I would like to replace a modernly powerful desktop iMac with a thin client running via my iPad. I will connect the iPad with a keyboard/mouse too so you get the idea. But I want to be able to use some of the Android phones as well (I guess most Android phones today has a good enough performance/resolution etc to run a thin client). Of course it has to be able to have input/output in sound. Printing can be solved by PDF/emailing etc - so no direct communication to the printer ports to USB etc is necessary. Is there such a service today? It should cost somewhere under something like $40/ month. I will run stuff like CPU heavy duty ableton for music production, xCode for making iOS apps, some games etc. And on the thin client also run virtual machines. VM of Ubuntu and Windows.

  • Long access time for static web page on virtual machine

    - by Karol
    My setup Windows 7 on workstation that I use at work (with domain) and home (no domain) Virtual machine (VMWare) that runs Arch Linux (I will call it just "Linux") with network interface in bridged mode. Linux serves web pages with Nginx. IP address of Linux machine is 192.168.0.16 and is added to C:\windows\system32\drivers\etc\hosts: 192.168.0.16 bridged bri IP address of Windows workstation is added to /etc/hosts: 192.168.0.10 workstation I can add more details to my setup description (I am not sure what is relevant). The question Often (but not always) it takes long time for a web browser (Firefox) to open static web page served by Linux. I am sure it is not a performance issue. To be more specific: it takes about ~20 seconds to resolve(?) the address http://bridged for a web browser. Additionally I have just installed samba service and noticed similar problem, so it is not specific to browser & http. Initial access for samba shares also takes long time.

  • Dell XPS 17 Laptop USB SS Ports don't work until machine rebooted

    - by Matt
    I have a new Dell XPS 17 laptop and have an issue that the two USB SS ports on the rear of the machine are not recognising anything when I start-up. Have tried mouse, keyboard, headset, USB display. If I plug a USB hub in the power light on the hub lights (presume this is hard-wired) but a mouse plugged into the hub does not light up. If I restart the pc the ports work fine. Also the other two USB ports work fine all the time. I have switched off the power saving setting on the device manager (Power managementAllow the computer to turn off this device to save power) and also in the advanced power settings (USB Settings USB Selective suspend setting:disabled) I have also disabled USB powershare in the BIOS (not sure what this actually does!) This is becoming very annoying having to restart the machine every day before I can start work Running Win 7 Pro x64 EDIT: I have found that setting USB Emulation to Disabled has helped the devices to be recognised during start up but they keep dropping out completely when in use EDIT 2: I contacted Dell about this issue who told me to update the BIOS driver, when I asked if I should downgrade from the factory installed A13 to the A12 posted on the dell website they said no. However there is now an A14 available on the website has anyone tried this?

  • Attempting to set up xampp and zend server on the same machine

    - by umbregachoong
    I am attempting to set up the zend server and xampp on the same machine but I am running into problems. I came across documentation on the zend site that said you cannot do this. However the folks over at apachefriends said you can. I have since discovered that I can run some of the zendframework examples within xampp by downloading the zendframework2 library and the skeleton app from git and I am doing this right now. However, I would like to know how to set them both up without having any conflicts both for the apache2 server and phpmyadmin. (One of the frustrating things is trying to load phpmyadmin in the deployment dialog by using the zpk tool in Zend). What I did in trying to set up both servers on windows 7 is as follows: First I have tried to set up the httpd conf files separately for each server, xampp running on port 8082 , and zend running on port 8088. At the time xampp would work, but zend server would not. This is after setting up the virtual host files separately for each server. Question 1: Where are the zend server error logs? Earlier, I was able to get both of them running configuring the xampp server httpd-conf file alone, however, I experienced problems with phpmyadmin even after configuring phpmyadmin on xampp to work on a different port other than 3306. Second question here: how to set up the two mysql phpmyadmin instances so they do not conflict with each other? Here is the xampp virtual host section: ##ServerAdmin [email protected] DocumentRoot "C:/xampp/htdocs/" ServerName localhost 8082 ##ServerAlias www.dummy-host.example.com ##ErrorLog "logs/dummy-host.example.com-error.log" ##CustomLog "logs/dummy-host.example.com-access.log" common Here is the zend virtual host section: DocumentRoot "C:\Program Files (x86)\Zend\Apache2/htdocs" ServerName localhost:8088 </VirtualHost> I have looked at this httpd.apache.org/docs/2.2/vhosts/ and this http://survivethedeepend.com/zendframeworkbook/en/1.0/creating.a.local.domain.using.apache.virtual.hosts but I am obviously doing something wrong here. I also have the java sdk running on this machine with tomcat and apache and I have no conflicts- too bad this is not the case for zend server and xampp Thanks umbre gachoong

  • Automating first time login process in Windows Server 2008 R2 SP1 virtual machine

    - by George Durzi
    I have a set of Windows 2008 Server R2 SP1 Enterprise Edition virtual machines running in Hyper-V. The host server has 64GB of RAM and two SSD drives (one drive for the host OS, and the second one for the VMs). The virtual machines are as follows: Domain Controller: 4GB RAM Exchange Server: 4GB RAM Terminal Services: 50GB RAM We use this setup for a travelling training class where users remote desktop to one of the VMs - let's call it the Terminal Services or "TS" VM - where tools such as Visual Studio are installed. The students go through some labs on the TS VMs in Visual Studio. Overall, this setup works great. However, when users are collectively logging in for the first time, the VM really struggles to keep up while all the user profiles are created. It can take some users up to 10 minutes to login. The number varies from 30 to 40 students. A workaround to this would be to manually remote desktop to the TS virtual machine using all the accounts to ensure that the local profile is created in advance. I'm looking for a way to automate the first time login process on the TS virtual machine. I am envisioning iterating through the accounts in a certain Active Directory OU, and then somehow initiating a remote desktop session to the TS VM to log them in for the first time. Are there ways to do this? Thanks

  • Tunneling a public IP to a remote machine

    - by Jim Paris
    I have a Linux server A with a block of 5 public IP addresses, 8.8.8.122/29. Currently, 8.8.8.122 is assigned to eth0, and 8.8.8.123 is assigned to eth0:1. I have another Linux machine B in a remote location, behind NAT. I would like to set up an tunnel between the two so that B can use the IP address 8.8.8.123 as its primary IP address. OpenVPN is probably the answer, but I can't quite figure out how to set things up (topology subnet or topology p2p might be appropriate. Or should I be using Ethernet bridging?). Security and encryption is not a big concern at this point, so GRE would be fine too -- machine B will be coming from a known IP address and can be authenticated based on that. How can I do this? Can anyone suggest an OpenVPN config, or some other approach, that could work in this situation? Ideally, it would also be able to handle multiple clients (e.g. share all four of spare IPs with other machines), without letting those clients use IPs to which they are not entitled.

  • OS X can connect to Windows machine, but can't access shared folders

    - by Bonnie
    I can create new folders on my Windows XP machine, set them to "shared". On my Mac, I pick Finder → Go → Connect to Server → smb://192.168.1.4 → Connect → Name / Password. It even shows me all the names of the newly created shared-folders on my PC, but when I try to actually connect to any of them I get connection failed, there was an error connecting Any idea on what would cause that? The fact that it successfully gets so far—to actually showing me my PC share-names—must mean I have 99% of this working correctly, i.e. the physical connection, the IP address, the user name, the password, etc. Still, I can't seem to access the folders themselves. I've tried this with my Windows XP firewall on/off, and Norton AntiVirus on/off. Same problem. Everything did work fine, 4 months ago. Were there any odd OS X or Windows updates released recently? I always apply them all. smbclient on the Mac does correctly find the XP machine, my XP user name, and accepts my XP password. I get the following from that smbclient command: Doing spnego session setup (blob length=16) server didn't supply a full spnego negprot Got challenge flags: ... Got NTLMSSP flags: ... Got NTLMSP flags: ... Domain=[XPMACHINE] OS=[Windows 5.1] Server=[Windows 2000 LAN Manager] tree connect failed: NT_STATUS_INSUFF_SERVER_RESOURCES I'm not sure why a standard XP box can't "supply a full spnego negprot". Whatever that means. Using XP's RegEdit to change my IRPStackSize from 11... to 13, 15, 20, 22... still gives that "NT_STATUS_INSUFF_SERVER_RESOURCES" error on the Mac.

  • Virtual Machine Network Services causes networking problems in Vista Enterprise 64 bit install

    - by Bill
    I have a Quad-core/8GB Vista Enterprise 64-bit (SP2) installation on which I installed Virtual PC 2007. I have a problem that is opposite of all that I found searching around the Internet--everybody has problems making network connections from their guest VM. When Virtual Machine Network Services is enabled in the protocol stack for my network card across a reboot, it causes access problems to the network. The amount of time to login in using a domain credentialed account is upwards of 3 minutes, then after reaching the desktop the network and sharing center shows that my connection to the domain is unauthenticated. Disabling and re-enabling the Virtual Machine Network Services (uncheck in network properties/apply/recheck/apply) fixes the problem. And as long as I have the VMNS disabled when I shutdown the restart runs smoothly. I just have to remember to enable after login and disable before shutdown. I have un-installed and re-installed Virtual PC 2007 multiple times with restarts between. The install consists of the SP1 + a KB patch for guest resolution fix. Any help would be greatly appreciated. Some additional information... At one point during my hairpulling and teethgnashing with this, I tried to ping my primary DC and observed some weird responses: (Our DC is 10.10.10.25, my dynamic IP was 10.10.10.203) Reply from 10.10.10.203, Destination host unreachable. Request timed out. Reply from 10.10.10.25: ... This is not consistently repeatable, but thought it might strike a chord with someone.

  • Process PHP files from a network share in a vmware virtual machine

    - by nhinkle
    As a testing environment, I have set up a vmware virtual machine running Windows Server 2008 R2. I have Apache and PHP installed (as part of the xampp package). I am doing the development outside of the VM, and so want Apache to serve PHP files from a VM shared folder (which appears as a network share in the VM). I have done this by creating an NTFS symbolic link in Apache's htdocs directory. I can access this directory from the browser, and plain-text files are readable. However, PHP fails to process files, instead returning the following error: Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'C:/xampplite/htdocs/path/to/file.php' (include_path='.;C:\xampplite\php\PEAR') in Unknown on line 0 It appears to be a permissions issue — PHP doesn't seem to be allowed to read the file to process it. However, Apache has no problem opening files in the directory. I cannot figure out how to give PHP the necessary permissions to process the file. Does anybody know of a way to make this work, or else another solution for getting the files into the VM automatically while I develop on the host machine?

  • Can I boot up a virtual machine natively?

    - by Anshul
    My question is: Is is possible to run a virtual machine natively on your hardware if you have installed the proper drivers etc? In other words, can I use a VHD as a regular hard drive to boot from? The reason I want to do this is that I do both graphics-intensive and audio-intensive work, but my computer is not powerful enough to handle both at the same time and many times I install a bunch of audio programs that I don't want affecting the stability of my graphics programs. Basically I wanted to have sandboxing between the two sets of applications. So I tried running the graphics-intensive programs in a VirtualBox VM and the audio-intensive work natively (simply because it's a pain to route ASIO audio devices in/out of VirtualBox). This kind-of works - the graphics-intensive stuff is tolerable, but still relatively slow, because it's running inside a VM. So my next idea was to just dual-boot and install the graphics and audio programs in separate partitions but I frequently use them in tandem, so it wouldn't be practical to reboot my machine every time I need to use the other set of programs. But I could live with this scenario: If I need to do more audio-intensive stuff, I'll just boot up to the audio partition and run the graphics programs in a VM, and then when I'm working heavily on the graphics part, I'll just boot the graphics partition as a regular OS directly on the hardware. Is this possible? For example by booting up a VHD as a regular hard drive? Or by setting up dual-boot, and every time the audio partition is shut down, synchronize the graphics VM VHD with the native graphics partition? Is it practical, given the above scenario? And if it's not possible, barring buying another computer, can anyone suggest a best-of-all-worlds setup (the two worlds being performance, sandboxing, and running in parallel) for the above scenario? Thanks in advance.

  • Deploying multiple identical copies of a virtual machine for compute tasks

    - by Reid
    I have a compute task which has a large number of library dependencies. I would like to deploy it on some of my company's large Linux clusters, where I do not have root. I could probably track down, compile, and install the right versions of all the libraries, but this looks to be quite tedious and would have to be repeated if I deployed it again somewhere else. On the other hand, it's pretty easy to install on current Ubuntu. This led me to wonder about a virtual machine approach. Could I put together a virtual machine which booted up, ran the computation (with parameters from and results to the host), and then shut down? In other words, I'd like a command like this that I could run on the host: $ ./run-vm --ram N --task /path/on/host/foo.sh --results /another/host/dir/ This would boot the VM, run foo.sh, and put the (relatively small) results of the computation in /another/host/dir/. It's important to start up many instances of the VM simultaneously, both on a single node and multiple nodes of the cluster. So it would be nice if I didn't have to make many copies of the VM virtual disk and metadata. As the task instances are completely independent, the VMs would not need any network support once deployed, or any outside communications beyond reading and writing the host filesystem. Is this possible, and if so, how might I go about doing it? Are there assumptions I've made above which are bogus?

  • KVM virtual machine unable to access internet

    - by peachykeen
    I have KVM set up to run a virtual machine (Windows Home Server 2011 acting as a build agent) on a dedicated server (CentOS 6.3). Recently, I ran updates on the host, and the virtual machine is now unable to connect to the internet. The virtual network is running through NAT, the host has an interface (eth0:0) set up with a static IP (virt-manager shows the network and its IP correctly), and all connections to that IP should be sent to the guest. The host and guest can ping one another, but the guest cannot ping anything above the host, nor can I ping the guest from anywhere else (I can ping the host). Results from the guest to another server under my control and from an external system to the guest both return "Destination port unreachable". Running tcpdump on the host and destination shows the host replying to the ping, but the destination never sees it (it doesn't even look like the host is bothering to send it on at all, which leads me to suspect iptables). The ping output matches that, listing replies from 192.168.100.1. The guest can resolve DNS, however, which I find rather odd. The guest's network settings (connection TCP/IPv4 properties) are set up with a static local IP (192.168.100.128), mask of 255.255.255.0, and gateway and DNS at 192.168.100.1. When originally setting up the vm/net, I had set up some iptables rules to enable bridging, but after my hosting company complained about the bridge, I set up a new virtual net using NAT and believe I removed all the rules. The VM's network was working perfectly fine for the last few months, until yesterday. I haven't heard anything from the hosting company, didn't change anything on the guest, so as far as I know, nothing else has changed (unfortunately the list of packages updated has since fallen off scrollback and I didn't note it down).

  • Windows Server 2003 (w/Exchange) move to new machine

    - by James Booker
    I have an ageing domain controller (the only one on a 10-pc network) which needs rebooting often. I have a Dell Poweredge 2850 server doing nothing, so I'd like to move the DC to that, but here's the catch - I don't have Win2k Server Std install media any more as it's been lost. I purchased "Easus Todo Backup Advanced Server" which claims to be able to recover to dissimilar metal, but it's not quite working (although I don't think it's the product's fault) I know the server and PERC RAID card are good because I installed Ubuntu on the logical drive (4 x 72GB disks RAID 5) no problems. I've booted frmo the Easus Todo backup CD (which is WinPE based) and recovered to the logical disk on the RAID (after installing driver inside the WinPE environment from a NAS drive) The problem is when I boot the server, I can get the OS selection menu, but any option results in a blank screen, with no errors. I figure this is probably because the driver wasn't installed on the old machine (which is IDE-based (i know, i know!) and doesn;t have a RAID controller) I've booted from the CD and copied the mraid35x.sys file to the c:\windows\system32\drivers folder on the recovered system, but it makes no difference. I made a boot.ini with rdisks 0-10 defined, and booting from each of these resulted in a file error (i.e. 'this isn't a real disk') - the only disk that gets any response (the blank screen) is multi(0)disk(0)rdisk(0)partition(1) which just gives me the blank black screen and no disk activity. Is there any way I can force the drvier to be installed on the source system (so i can do a full backup again), i've tried right-clicking the oemsetup.inf and clicking install, but it didn't actually do anything. I attempted to force it with the 'Add new hardware' wizard and forcing with the 'have disk' option but it still gave me no hardware to select. Also I've got an identical machine running WinXP which uses the PERC driver successfully (which was obviously done at install time) and the boot.ini settings are the same : multi(0)disk(0)rdisk(0)partition(1) Any ideas would be appreciated.

  • Intranet machines refuse to talk anymore

    - by ashes999
    I have two machines on the local intranet. They used to be able to talk to each other (ping, share files, etc.). Both are not successfully connected to the internet. The problem machine (lets call it test machine) can't talk to my main machine. The test machine can ping other machines on the intranet (at least one of my coworkers), but not mine. Odd. When I try to ping it from my machine, by machine name, I get Destination host unreachable. Both machines are on the intranet, with the network configured as Work Both machines have Windows Firewall disabled temporarily Both machines can talk to the internet (Google, SO, etc.) Neither machine can ping the other I need help resolving this. What I really want to achieve, is to remote into the test machine from my main machine, like I used to be able to do a few weeks ago. Some notes: Tried arp -a on both machines. I don't see the other machine's IP listed. Both machines have stable IPs; neither seems to have an IP conflict The configuration under ipconfig /all on my main machine mathces my coworker's machine. The test machine can ping his machine, but not my machine. The target machine times out trying to ping the main machine; the main machine gives me Destination host unreachable. I have rebooted both machines (several times) to no avail I have /release and /renewed both machines several times
