• Why do the IP addresses randomly change?

  - by GiddyUpHorsey

  I have a network with the following: Cable modem with static IP address Router Desktop - Win 7 VM Host - VMware ESXi 4.0 A couple of VM Guests - Windows Every now and then my Win 7 PC is unable to access some of the VMs. When I ping the VMs by their domain name their IP address shows up as the IP address of the cable modem. Sometimes I can fix it by running ipconfig /flushdns. The IP address will reset back to what it was supposed to be, but occasionally it wont work. Why does this happen and how can I fix it?

• Locking down a box on the web

  - by glowcoder

  I'm a Java developer who is looking to put a game on the web. I'm not much of a web or server guy, though, and frankly I seem a little lost at where I should start with putting something on the web. My application works fine on my machine, and I'm sure I can make it work fine on any box I put it on. But the security of that box is pretty important. If I sign up for a standard hosting package (let's say from GoDaddy or something) can I simply tell them "make port 12345 open for communication" and let them handle the rest of the security details? If I can't, what are the things I'm going to need to know to prevent my game server from getting hacked to shreds? (Links to solid resources fine by me!) Thanks!

• Can't figure out how to make Slitaz USB persistent

  - by Dennis Hodapp

  I installed Slitaz on my USB. However I can't figure out how to make it persistent automatically. There are different sources telling me different ways to make it persistent. One told me to add "slitaz home=usb" to the syslinux.cfg file like this: append initrd=/boot/rootfs.gz rw root=/dev/null vga=normal autologin slitaz home=usb but it didn't work for me. http://www.slitaz.org/en/doc/handbook/liveusb.html gave an example of how to do it manually but I didn't try it and I also want it to happen automatically. custompc.co.uk/features/602451/make-any-pc-your-own-with-linux-on-a-usb-key.html is an older article that also explains how to make the USB persistent but I don't want to try it cause it looks outdated (from 2008) does anyone know the best way to make the USB automatically persistent?

• Application Compatibility Clients do not show in MSSQL database, but do show in \AppCompat\

  - by rjt

  Application Compatibility Clients are not denied access to the central MSSQL database, but are able to leave their own files in the \AppCompat\ share. The only computer that shows up in the "Microsoft Application Compatibility Manager" database is the the machine i initially created the .MSI installer from. The MSI successfullly pushed out via GPO and like i said there are tons of file in the \AppCompat\ share from many different computers. But only 1 pc shows up in the "Data Collection Manager" database, so i only have data from one machine. i could manually add all these machines (ADNETBIOSNAME\MACHINENAME221$) to the MSSQL AppCompat db permissions list or use an SQL command to do so in batch, but i suspect i must have missed something. Do you manually edit the MSI to set the credentials?

• Dell XPS 420: Turning computer on, video ports showing static

  - by Roy Rico

  I have a Dell XPS 420 which i recently upgraded with a EVGA GTX 550TI and a 80GB SSD Drive. I converted this machine into a home theater PC. Which I've always had on. The computer wasn't responding, and so i restarted it and when it started, video ports showing static. I was getting static on my TV thru both DVI ports and the mini HDMI port. I assumed my video card had gone bad, but i completely replaced it and still the same behavior is occurring. I do not know how to diagnosis this issue. Any thoughts?

• OpenVPN not with Windows 7 PCs on client Lan

  - by Rohan

  I have a setup with a router running OpenWRT with an openvpn client. Windows 7 pc's cannot access the vpn. They time out trying to access servers on the VPN. The mystery to me is that the setup works fine for my laptop running ubuntu. I can access the VPN without any issues. I previously had a router running Tomato with the same openvpn setup and all the computers could access the VPN. What could account for the difference in behaviour? Is there something I am missing in the OpenWRT setup that is required for windows networking that is on by default with tomato? To clarify the OpenVPN client is on the OpenWRT router. The client connects to the OpenVPN server. But when I try to access the VPN from Windows computers on my network I cannot.

• Ping computername - result format

  - by kamleshrao

  Hi, I am trying PING command on my Windows 7 PC after many months.

  - by user47354

  on win 64, I installed apache, php etc. Everything works fine, except the oracle part. I can connect to oracle from sql developer which means my tnsnames.ora file is correct.

• Identifying the version of ATI Catalyst drivers

  - by snark

  I have bought a new video card based on the ATI Radeon HD 5670 chipset. I couldn't make it work with the latest ATI Catalyst drivers found on their website, only the drivers found on the CD delivered with the card worked. How can I know the version of Catalyst that is installed on my PC (running Windows 7 64-bits)? The ATI Catalyst Control Center returns the following information: Driver Packaging Version 8.673-091110a-092263C Provider ATI Technologies Inc. 2D Driver Version 8.01.01.973 2D Driver File Path /REGISTRY/MACHINE/SYSTEM/ControlSet001/Control/CLASS/{4D36E968-E325-11CE-BFC1-08002BE10318}/0000 Direct3D Version 8.14.10.0708 OpenGL Version 6.14.10.9120 Catalyst™ Control Center Version 2009.1110.2225.40230 I do not recognize anything pointing to a "marketing version". The website says the current version of Catalyst is 10.2.

• DSL connection dropping when starting game

  - by bootoo

  New connection set up last week - have called tech support, signal fine, sending out tech guy tomorrow - however i cant make sense of this using Vista, 2wire connection 6mb ATT conn, wireless, i can browse website, stream video from my PC wirelessly to my xbox, watch Hulu in high res, connection seems fine I load up World of Warcraft, i select Enter World and without fail my 2wire modem 'DSL' light goes red, my internet light goes out, im no longer connected, then after 10 or 15 seconds it works again, but game has kicked me Noticed the same thing on opening or closing Utorrent as well No other phones/devices plugged into the phone jacks in the apartment - why would joining a game cause my DSL to drop? i can only guess it throws a bunch of information to the server when i hit 'enter world' and that causes an issue that shuts my connection down or my router hates me - all help appreciated

• Can I upgrade my Soltek sl-67a-c motherboard from Pentium II to Pentium III?

  - by jedatu

  I have a Pentium III processor and I thought I would replace the Pentium II on my Soltek SL-67A-C. The motherboard has Slot 1 so the PIII fits in fine, however, when I turn on the computer the bios does not come up. Here's the link to some specs on the board: http://stason.org/TULARC/pc/motherboards/F/FLASH-TECH-INC-Pentium-II-Deschutes-SL-67A-C.html I know that I updated the bios at one time. I see references to a "67af3.zip" bios upgrade file out there but can't find any source to download it. I am thinking I may have to adjust the jumpers on the motherboard to match the speed of the processor, but I am not sure how to go about that. Any suggestions?

• What is the best position for power unit?

  - by guest86

  I would like to buy new computer case. Last time I bought a computer was in 2008 and many things have changed up to day. Many new computer cases have power unit placed down, on bottom. I'm thinking about buying some of those cases, but i'm not sure about something - if power unit is placed on the bottom it can't take away hot air from the case and pump it out right? All my PC parts are silent - CPU (E8200, placed below 12cm Nochtua fan of power unit) has heat-pipe cooler with Nochtua fan spinning at only 800rpms, GPU has cooler powered by 7V instead 12 and that's why i don't want to HAVE TO place another fan to pump out hot air instead of PU placed on top. That might make some noise. So i ask someone more experienced: if i buy some computer case with PU placed down, do i HAVE TO place some fan to pump out hot air?

• How to determine source of file corruption for downloaded images?

  - by sunpech

  I've been downloading Visual Studio 2010 off of the Dreamspark.com website using Akamai Downloader. The .img file is 2.2 GB in size. I've downloaded it twice so far, and when I try to mount it using Gizmo, it complains that "the disk structure is corrupted and unreadable". The drive does mount, but it is unreadable. Is there a way to determine where the source of the data corruption is coming from? Is it my computer as it's receiving it? The hosting server(s)? My ISP? My router? My ethernet cable? It's a hefty download to do again and again from home, only to find out once it's fully downloaded that it's unreadable. I think I can almost rule out my PC, router, and ethernet cable, as I've been able to download various other files without corruption. Note: There is no checksum to verify against

• front end to linux std mailbox for development purposes

  - by Fabio

  I am actually a software developer, do have a fair amount of linux experience as a user though since 1997. I am normally on stackoverflow.com, please excuse me if this question isn't appropriate here. I am working on a web project. We send out emails. I work locally on a linux box. When coding I use my local mailboxes to check what's been sent. Emails sent out to valid email addresses are not arriving at my official mailbox; they might be stopped by the provider's mail servers (gmail, yahoo). Now, we are sending out HTML mails too. I need to check how they look like. Is there a GUI frontend to the standard linux BSD mailbox? Or should I install some IMAP/POP server for this? Will such server get the emails sent to username@localhost ? Thanks for any suggestion

• How difficult is it to setup Mac OS X Server?

  - by Anriëtte Combrink

  Hi there We are a small office of about 4 people, and we would like to have a 27-inch iMac (Core 2 Duo) setup as a server and workstation simultaneously, using Mac OS X Server. This might seem like overkill (and stupidity at the same time), but here is the situation: we want to convert our whole office to Mac, only one full-time PC left we will not use it's mail server we might use it's chat server we want it setup to provide VPN we are a small office so I don't see how the server can be overrun with too much traffic. How difficult would it be to set it up in this way? I have a fairly advanced knowledge of Mac OS X but have never encountered Mac OS X Server. I think I would be able to set it up, but what are the probable pitfalls that might come up? Has anyone else been in a similar situation?

• Tunneling traffic through two VPN hops/tunnels.

  - by Roberto Sebestyen

  I am a web developer, and I find myself often working from home. But when I do, I am forced to Remote Desktop to the Office desktop computer and work from there. The reason is because the application I am working on needs to connect to servers at a Data Center via a VPN from the Office Desktop. HomeDesktop (Win7) --- PVN --- OfficeDesktop(WinXP) --- VPN --- Data Center What I would really like to do is, I would like to find a way to be using my Home desktop developing on that, and whenever my computer tries to access servers on the Data Center, I would like to tunnel that traffic through the two VPN tunnels separating me and the Data Center. I have admin privileges on both Office Desktop and Home Desktop, but I do not have any admin privileges in the Data Center. So what kind of tunneling solution could I use here? Is it even possible?

• How to determine if a device is SATA driven and will be affect by the Sandy Bridge Intel Issue?

  - by joelhaus

  Looking to buy a higher-end Windows 7 laptop, but I'm concerned about the issue with the Intel Sandy Bridge chipset. Otherwise, my price range covers laptops within the latest (Sandy Bridge) generation of the Core i7 family. I understand that there is an issue with SATA ports 2-5 and I use a Windows Home Server over a WiFi connection to share files and backup my PC. The other storage devices that I will use (less frequently) are the built-in DVD-RW disc drive and various devices hooked up to the USB ports (i.e. Android devices, iPod, etc.). The question: Will this setup be negatively impacted by the problem Intel reported about Sandy Bridge? Given this information, is it unwise to purchase a laptop that has this flaw? I really don't know how to determine whether a device is SATA driven or not, so hoping someone can shed some light on this too. Thanks!

• PPTP network for server backend LAN?

  - by Sebastian Hoitz

  Here is our problem: We have several webservers, which should be reached from public. The database servers that store the data for the web apps on those webservers though shall not have a public IP. So, since I want to be able to connect to the SQL servers using ssh for example, and those servers need to talk with each other, I had this idea: Internet | ------------------ | | Webserver 1 Webserver 2 Database Server | | | -------------- vLAN -------------- | PPTP | Workstation (my PC) My idea was that I can connect to the vLAN using PPTP so that I have access to all servers in that LAN, but the database server remains unvisible to the public. Is this infrastructure a good idea?

• ADMIN$ and other shares not working remotely on XP machines

  - by makerofthings7

  I'm trying to use ADMT to migrate several XP machines to a new domain and the utility (nor command line) is able to access the admin$ share or any drive share. I've added the required registry key (HKCurrent\Services\LanMan\Param) for both servers and workstation admin sharing, rebooted the PC and still am unable to access it. How can I access the admin share on these PCs? If it helps, this machine used to have McAfee installed, and the Windows firewall enabled. I stoppped both of them and the machine is still not allowing me to access it remotely by a drive$ share.

• Using Performance Monitor To Get IIS7 Response Turnaround Time

  - by alphadogg

  I have a MVC2 web application on W2KR2/IIS7 that I'd like to benchmark/monitor. Some XHR requests by a browser-based client are suddenly taking 8-10 sec when they used to take much less time (as per Chrome Developer Tool timings). The underlying SQL Server queries, using the same params, runs in 1.4s according to total execution time client statistics from SSMS. I'm assuming that there are various counters that can specifically dissect time taken/waiting/processing between IIS7 itself and the web application? For example, can I check how long it takes to get a response from IIS7 app and DB? How about how long it takes to serve IIS7?

• Shut Down took way too long because of "Background Programs"

  - by Christopher Chipps

  I tried shutting my desktop PC (with Windows7) down but after several attempts (like 4 or 5) at Start -- Shut Down, the GUI was still there and it was not shutting down. I didn't think there were any programs running when I pressed Shut Down, so I went into the taskbar (Ctrl + Alt + Del) to check out the processes. Once I did that, a screen appeared with a message stating that there are "background programs" still running and it gave me an option to "Force Shut Down" which I pressed and it shut down normally. Does anyone know why this would happen?

• powerpoint make computer shut down on dell optiplex 760

  - by yael

  At my office we upgraded group of computers to windows 7 + office 2010, few of us have problem that when we work on powerpoint - once in a while the computer suddenly shut down (with out any message). Some of us - has no such problems. We checked and fount that the people who experience problems - use Dell Optiplex 760 PC, and everyone that have no problems use other models. We also found out that the processors of the 760's are not the same - some are Intel E7400 and one is Intel E8400, so I suspect that maybe the mother board is the problem Does any one no this problem? Does any one have an idea about it? Any help will be appreciated. Thanks, Yael

• XP IIS no longer listen to port 80 or 443 after installing Oracle 9i HTTP Server

  - by Nassign

  I have installed Oracle 9i HTTP Server together with the database. After restarting the PC, even though i restarted the IIS and stopped the Oracle HTTP Server. When I go to http://localhost/ The starting page is already the Oracle HTTP Server index page. Also when I look at the port that inetinfo.exe is listening to, it no longer listens to port 80 and the SSL port 443, even if i restart the IIS and World Wide Web Publishing service. Any idea what setting did oracle changed when I installed oracle 9i? The executable associated with the OracleOraHome90HTTPServer is C:\oracle\ora90\Apache\Apache\Apache.exe I already checked the tasklist and Apache is really not running. But there is no process listening to port 80 still even if the IIS restarts successfully. Any ideas how to fix this?

• Installing Win8 from ISO image error

  - by eco_bach

  I installed a new SSD in my PC laptop which came with an OEM version of Windows 8. After trying unsuccesfully to get the OEM version of Windows onto the SSD drive I gave up and purchased and downloaded a NEW copy of Windows 8. After that I created an ISO image on my desktop machine and followed the instructions here to create a bootable USB flash drive. However, after going through the boot install process with the USB flash drive on my laptop I get the following message 'The product key entered does not match any of the Windows images available for installation. Enter a different product key.' But I wasn't asked to enter any key! Is this because the ISO image was created on a different machine? I really don't get why this should be so difficult.
