    Hey Valnar, just curious where you were laid off from? I'm in the Cleveland area too... Wish I had something to offer you, but we just went through layoffs here in November. (I know you didn't work where I do. :) The one employee I had to lay off in November started a new job near Akron...

    UPS recommendation for server rack? (both 220v/110v; mostly needed for 1-2s outages)

    Honestly, it's been awhile since I've looked in any depth, but I think you're going to have some trouble finding a UPS with both 120v and 208/220/230v outputs in the same device. If you've got devices absolutely need 120v, you might need two UPS's to handle the power requirements. I know a...

    5PX2200 UPS cooling & noise management

    Sorry to ressurect an old thread... I too was wondering if the OP ever replaced the fans in this UPS. I have a similar model (5PX1000rt) and have at least one fan that's rattling and probably about to fail. (The UPS is in a somewhat dusty environment, and I have to blow the dust out of the...

    The shady world of AV

    I agree that the people discussed in the article are scumbags, but honestly, they're not A/V vendors. (Hence the title of the post if a bit misleading.) While I'm not a huge fan of real A/V vendors, real and reputable A/V vendors don't pop up random web pages meant to look like legit warning...

    How do you label small cables?

    I've had good luck with Panduit self laminating labels. I print up enough sheets for whatever project I'm working on, and a couple extras. I also keep some blanks in my bag for random cables, and just write on the white part with a good ol' Sharpie...

    Domain controller specs

    You really don't need much horsepower to run a domain controller with DHCP and DNS... A 5 year old consumer PC with 4GB RAM has more then enough horsepower to run those services (assuming a modest number of GPOs, etc). However, remember that a DC does become a critical component of an...

    View files a program is accessing in Windows

    The sysinternals tools are the best, but also remember in a pinch the perfmon app in Windows 7 & 8 will show this info too... Run: perfmon /res to run perfmon in Resourse Monitor mode. Then look at the Disk tab to see current activity on files in the system. Check the boxes in the...

    Testing an RJ45 Cat5 wire?

    Just to be clear: A simple cable tester like the OP described won't tell you anything about the quality of the connection... A professional (AKA expensive) tester will tell you all kinds of info about the quality of the connection (various types of cross-talk, noise, reflections, etc)... That...

    Testing an RJ45 Cat5 wire?

    While it's true that wires 4-5 aren't used in 10/100-base-T, they would be used in a gigabit connection, so depending on what hardware you have at each end, they could cause trouble...... Even so, most gigabit gear will fall back to 100 fairly gracefully if the gigabit connection can't be...

    is windows 8 a network hog?

    No need to download a third party app just to get basic stats on network utilization... Hit Start, then type perfmon.exe /res to open Performance Monitor in Resource Monitor mode.. From there you can hit the Network tab to see Send and Receive bytes by application. this will show you what, if...

    Failed - Network error - Help?

    It sounds like you've covered the bases pretty well in your own network... Steam game downloads might appear OK because the Steam client will automatically retry and resume dropped connections... One step up from a simple ping is something like WinMTR ... If you are dropping packets to the...

    MS dumps 7 support?

    Here's a +1 for WDS + image updating combined with WSUS... Worked wonderfully for my org for many years before we finally put in SCCM (which works well too, especially since so many of the components from WDS are really just taken from the deployment components of SCCM)... On the other hand...

    Front end for AD Attribute management

    Are your user accounts synced with AD to O365 (DirSync / FIM), or are the user accounts hosted on O365 itself? If the user accounts are hosted in an internal AD and synced, then any of the methods for allowing users to update their own internal info are still applicable. The changes will...

    Discover IP/MAC address w/ Crossover?

    Does the device have a serial interface? You may be able to manage and perform some low level config through that... Have you cracked open the case? what type of system board is in the machine? Have you tried looking up the board online to see if there's any documentation?

    Discover IP/MAC address w/ Crossover?

    Yeah, run wireshark on the one XP machine while you apply power and boot the headless device... Watch to see if the headless device sends out DHCP requests. The DHCP request will have the MAC address of the device requesting an address. If you do have to resort to nmap... Use -T5 to set...

    Exchange: shared calendars?

    I'm not sure there's any hard or fast rule that can be applied to choose between a shared mailbox or a Sharepoint Calender in the scenario you've laid out... I think it will just depend on where you and your users are most comfortable. If your users are very "Outlook centric" then the shared...

    New to Networking

    Not affiliated with these guys in any way, but it might be worth a look. Full access to the site will cost you about as much as a couple courses at a community college. (They run commercials on the TWIT network, with ads to give you 50% off a year's subscription.)...

    100+ Connections. netstat -a Normal?

    What you're seeing might not be unusual for your system, depending on what' background services are running on it... Instead of netstat -a, run netstat -ban to see what process is creating the connections. What's listening on those high level ports? (49xxx) What process is making those...

    NSA Patented The Secure Manhole

    If the NSA wants to patent this kind of stuff, fine... But since this was paid for with taxpayer money, then it should at least be freely licensed to all US based companies who want to manufacture a device based on the patent.....

    New home, PoE info

    The point isn't whether some other device or interface can saturate the connection today, the point is whether there are going to be applications which requirements drive more bandwidth to the edge? You're right, we didn't have 100Mbit Ethernet 20 years ago... It's 18 years old now...

    New home, PoE info

    Cat6 will run 10GbE over 40-50 meters under optimal conditions (single wire, direct device to device; computer to switch, computer to computer, whatever). Once you start adding patch panels or wall jacks, that drops off really quickly as cross talk and reflections become real problems. Add...

    Tracing RTP packets using RTCP??

    You really haven't provided enough info to work with. I assume, first, that you can't replicate this in a network you control? It only happens on the Internet? (just to be sure there's not something in your app that's introducing delay in delivering the media stream to whatever libraries...

    Server 2012 VM License Usage

    bigdogchris: great explanation, however I think this point needs more clarification. IIRC, the Windows Server Standard license requires that both VMs offered by the license must be installed on the same physical host (server, blade, whatever)... You can't put a "single license" with the two...

    600 ft wifi range...

    You can try. Yes, You can make due with a directional antenna on only one side of the link. I've successfully used a "can-tenna" to allow a friend to connect a laptop to his house's WiFi on from his barn, over 500ft away. I could induce packet loss simply by shaking the rod the can's...

    Transformers Fall Of Cybertron $11.99

    Picked it up last night. Played the first game on the Xbox, but at that time I didn't have a decent gaming PC. The first game was fun enough, but a bit short. If this game is similar, I won't complain if it's a bit short at this price! Thanks.

    wake on lan question for home network

    Generally, most people on SOHO networks (those with single subnets or VLANs) simply broadcast the magic packet. Certainly in a home environment, this is what I'd do. Now, to the original question on whether to let a PC sleep or keep it on all the time... This is one of those questions you can...

    NMI Parity Check - Memory Parity Error

    Exchange Email Export (when domain is fubar)

    You said the domain died, but then you said it was running on SBS? Normally Exchange is running on the SBS server, which is also a domain controller. Therefore you should just be able to fire up that server and still have access to exchange and the old domain in that single server. Then...

    End of mainstream Windows 7 support

    I guess I just don't understand what the big deal is for most consumers? Microsoft is only stopping standard support in 2015. This includes improvements, and hotfixes... How many consumers, or businesses even, are asking for improvements or hotfixes to a fairly stable OS after 5 years? Sure...

    Do you have multiple sites that are reachable across the WAN? If no, then it doesn't matter.....

    58 XBox One Systems Stolen

    Sure, why not? I use ebay prices all the time to figure out what old gear might be worth to someone else. If someone's willing to pay $1000 to have it before launch day, than the system was "worth" $1000 to that person. Remember, retail cost <> worth... Most new blu-ray discs cost $20 or...

    HyperV Windows Back and Exchange 2013

    What version of Hyper-V (Windows Server)? Are there any errors on the Hyper-V host's event logs after the guest goes offline? We had a similar problem with Hyper-V guests and Windows Backup under certain circumstances, on Windows Server 2012. The issue was related to heavy guest...

    ISP limiting number of connected devices

    OT: It's not just the "small ISPs" that are doing this. Big ISPs are starting to put their consumer grade customers behind "carrier grade" NAT devices too. Most consumers never know the difference. Verizon is just one example...

    Network crazyness

    +1 to what notarat said. Learn to at least split your thoughts into segments (paragraphs). :) jjandrob has a good thought. If you don't want to power down everything first, at least disconnect the links to the other switches and re-test. I've seen similar problems when someone creates...

    ISP limiting number of connected devices

    +1 to what Mopower said. It's more likely they're talking about 3 direct connected devices, not 3 devices total. (If they are really talking 3 devices total, let us know which ISP so we can stay far, far away from them.) Get yourself a NAT router (any home / SOHO router is a NAT router)...

    Scriptable VOIP Softphone?

    Macco: sipcli looks interesting, but the licensing model is a little unclear. I'll have to look at that one a bit more. I was looking at pjsua, but it doesn't appear to support auto play of recorded files on outbound calls (only inbound calls), unless I missed something? dizzy: Not...
