    How to ensure that users are migrated from expired Office licenses to active ones?

    It seems Microsoft just adds all purchased licenses to a total count without distinguishing between resellers. Then users just use a license from the total count. I recently quit using a reseller for my 'Microsoft 365 Business Standard' licenses and instead directly ordered the same amount of...

    Grounding network gear inside of cabinet

    I think if any of your equipment is small enough to be powered by a seperate powerblock with 2 pin connector, it likely is not grounded. So you probably should connect these steel cabinets to ground seperately (most likely already done by mounting them in the rack). Bigger equipment with a...

    making a very narrow slot with a desktop CNC machine

    As a rough guide : Sic marking lasers (or competative brands) probably are in the range of 15.000 -20.000 dollar or more. For 1500 euro there probably are some systems on alibaba, but most likely without any protection or cabinets. Although some searching might surprise you. These lasers...

    making a very narrow slot with a desktop CNC machine

    I think this can be done with a marking laser (if you can find one in your area). Fiber or YAG laser that is. CO2 lasers will probably not work on raw aluminum (the light has no effect on raw aluminum, only on anodised topcoatings). Depending on the type of lense used 30 um is achievable...

    Washing machine trip the breaker. RCD i guess. Basic questions.

    Frankly I disagree that no current can flow through the waterlines. It should not, but it can. Waterlines are connected to the same chassis and thus ground as the rest of the machine. That is why (in the Netherlands, don't know US laws) waterlines need to be grounded to earth. In the old days of...

    Drive displays in BIOS, but not in DevMgr or Disk Management

    Apparently Windows is using a disk ID identifier to identify a disk. That ID should be visible with for instance diskpart. I noticed that Windows will complain if an identical identifier is used for another disk and Windows will then not allow you to use the second disk. I saw this situation...

    Drive displays in BIOS, but not in DevMgr or Disk Management

    Could this drive be a full clone from another disk in this PC ? I recently cloned a disk to a bigger SSD. Then I booted into Windows with both disks still attached. I found that because the new disk received an identical identification code as the old disk, then Windows would not show both...

    Jet 4.0 OLE DB driver problem with Excel

    As I understand, this driver is not changed since 2002. And for sure, this change broke it. While Microsoft does consider it deprecated since 2002, I also found comments that modern features in MS Word are still using this to import data. Also, I think MDB files (access) are not affected, only...

    Jet 4.0 OLE DB driver problem with Excel

    Just in case anyone else got hit by this; The october 10 Windows updates broke the JET OLE DB 4 drivers, causing some applications to be unable to connect to XLS (Excel) files anymore. The error you see is "Unexpected error from external database driver (1)." I used this driver (years ago) to...

    Dedicated label printer?

    Industrial labelprinters are very good at what they do; printing labels from a continuous roll of material (either sticky back labels, or plain paper tape or even plastic tape. They come in many brands and variants, from light to heavy duty, from table top systems to built-in systems for print...

    USB > RS232 adapter

    I use these: http://www.manhattan-products.com/usb-t ... -converter . Works on windows 10. Interestingly these converters work better than the native serialport that is built into my new HP ProBook 650G2 laptop (which seems to have a problem at higher baudrates like 115200) !

    Outlook problem adding 2 Exchange accounts from different domains

    Hi Cazman007, Basically I never fixed this, for this specific user. Sorry. The user (a remote user who is in our office maybe once a month or less) decided she did not care and now uses a different way to work (uses remote desktop for the second domain, so now she only has my domain in...

    Three-Phase Electric Railways

    w00key (and others), the reason you end up with a shortcircuit, is because on normal domestic (or Industrial) power the ground is already connected in the centre point in the generator of the powercompany. That is what they always do in normal generators / powerplants . They also always do that...

    Three-Phase Electric Railways

    In a 3 phase system there is a centre point. (like the optional neutral in the Wikipedia image). In domestic power this neutral point is normally grounded to earth, giving 3 phases with equal voltage to ground. (and 120 degrees of phase shift between the phases so there is voltage between phases...

    Outlook problem adding 2 Exchange accounts from different domains

    Hi all, I seem to have run into a problem with Outlook 2013 yesterday, when adding two exchange accounts into a single Outlook profile. That seems to mess up Outlook. I only see one accountname in Outlook in the folderlist, of which the inbox folder however contains the mail of the other...

    PSA : Don't install the following windows updates this month

    I think WSUS lists both versions of the update and then should indicate the old update as replaced. So when the new update is there, it should be OK. However: on my server the old version was dated nov.11 and the new one nov.12th. Not Nov.11 But that may also be timedifference (I'm in GMT+1) or...

    PSA : Don't install the following windows updates this month

    So far the re-release seems to be OK. Maybe the best bet is to delay updates slighty longer than 1 or 2 days, to avoid these problems. I recall reading that with Windows 10 normal (home-)users get updates immediately and business users get them delayed ?

    Mini metal foundry - melting aluminum at home

    Just a safety reminder on throwing cans in the furnace; make sure there is no water in these cans. That might cause an 'explosion' resulting in splashes of aluminum coming in your direction. (Courtesy of a local aluminum smelting plant I visited a few weeks ago, they made a big issue of this...

    PSA : Don't install the following windows updates this month

    Old topic, but OK; This weeks Windows update that might not work so well is KB3097877 Security update for Windows. I had this automatically installed by WSUS on my PC's. All Windows 7 with Office 2010. On several PC's Outlook crashed instantly when opening some e-mails in HTML and with...

    Variac - Do they only allow you to modify output voltage?

    As stated a Variac can only change voltage, not frequency. I don't know if a double conversion UPS will accept a different input frequency without shutting down with an errormessage ? You might want to try to rent a diesel generator and have that set for a different frequency than normal...
