    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...
