    So, if you ever wondered, there is in fact a rhyme and reason to windows error codes.

    Windows error codes are numbers, they can either be spat out in base10 or hex.
    1. If your number is in base10, convert it to hex, if not, you have saved time and can now move to 2 you lucky duck
    2. take your hex number and cut it in half
    3. Convert the second half of your hex back to base10
    4. Run 
      net helpmsg <number in base10>

    Enjoy your new, human friendly, error message.

    The first half corresponds to the source of the message, the latter the actual error

    Hooray!

    A less involved (and more intuitive) way to decipher windows error codes is to do the following:

    1. Surround the device generating the error in a salt circle of standard dimensions.
    2. Place an offering in the circle and incant the passage listed on page 23a of the install guide. (Contrary to popular belief, a live sacrifice hasn't been required since the 1998 antitrust lawsuit. Popular alternatives are an offering of a choice food item such as a cookie or a shot of whisky, a printed and then scanned and then faxed copy of a complaint from a user, or a piece of broken printer hardware.)
    3. Break the salt circle with a wand of ash.
    4. Burn the offering and breathe in the fumes -- the answers should come as a dream the next time you sleep.

    I'm starting to be at peace with this stuff, because I've come to understand that in a way I AM this thread.

    Remember that one time I banned myself when heartbleed came out because I kept trying to post here over and over and eventually racked up like 8 points and it banned me?

    I thought it was in jobs thread in SE but it might have been in here. Was there someone doing basic user/cybersecurity training for non-IT folk in here a while back? I have some questions for that person.

    Also anyone near Herndon, VA and have some decent computer experience want a job supporting the DoD as Tier 3 support on a network scanning tool? I think the position needs a Secret clearance, but the organization may be willing to sponsor one.
    If you have server/vm experience that'd be a plus, but honestly at this point I think we're a bit desperate. (Though we need someone who is fairly self-sufficient.

    I have enough computer experience to fail my Network+ by 20 points, but I have an active Secret. How much will you pay me?

    @Decomposey Well, you'd need the Sec+ 6 months after hiring(Net+ would be a bonus thing really). Pay seems variable? Not sure what your expectations are.

    "iDRAC8 Enterprise, integrated Dell Remote Access Controller, Enterprise". $300 and fucking worth it. You can connect to the console on your iDRAC if the server is powered off, mount an ISO from your laptop at home, and boot the server from the virtual optical drive you mounted it to. It's fucking amazing.

    It has its own dedicated port for the iDRAC, so you're not eating a QP NIC port for that.

    The single QP is probably enough. You don't need a vMotion dedicated port with a single host, so you designate one port for your ESXi management interface, 3 for VM traffic, and the iDRAC is on dedicated hardware. That's plenty. The other 3 NICs will team through the vswitching so you essentially have a 3 gig nic.

    Remember when you create VMs or P to V your current environment or whatever, to use the VMXNet 3 virtual NICs.

    Yeah, you only need 8 ports if you're doing SAN stuff (and that stuff should be on it's own switch if possible).

    Even if you had a dedicated vMotion port, 4 is probably enough. It takes a *fuckton* of traffic to saturate dual gig NICs.

    EDIT: Plus you can get 10 gig copper now.

    I was playing around with the dell configurator for funsies.

    I'd like to take a moment to appreciate how cool it is that we can get a 1U server with almost 32 TB of SSD storage, 36 cores running 64 threads, a half terrabyte of ram, and quad 10 gig NICs.

    good god. I went to give the weekly backup tape to the accounting person who takes it to the bank every Thursday.

    I was pretty devastated when she told me that Thursday is tomorrow, not today.

    I was planning on maybe going to vmotion one day, but maybe I'll just run everything off local storage 5ever rather than invest another 30k in SAN stuff.

    When you have one server it's doable, but when you get to multple VHosts you really want to have some kind of common/shared storage. It's way more efficent, and makes moving VM's between hosts way easier.

    When you decide to go to two hosts, you'll want three and a SAN. So nice to be able to move everyone, take down a host, patch or fix it or whatever, bring it back up and no one is the wiser.

    From what people have told me, moving VMs is no big deal between hosts. Like a 10-15 minute jobber, that's something I can live with to improve my current problem of me never being able to do server maintenance ever.

    I'd love to be able to do vMotion and seamless takeover but until I can get my boss to okay another 30k dumped into it that's a pipe dream.

    It'd probably be 10-15 minutes *per VM* if you have to move the VHD's. when you get to 10+ VM's that adds up quickly. If the VHD lives on a shared storage medium, then it's seconds per VM.

    again, with one host it's fine. But when you want to expand, you'll find that shared storage is a way better option.

    Our little upgraded webapp I've probably complained on here about once or twice is finally getting its big boy pants on.

    They did a full conversion of test databases and it only took a spritely 12 hours to run through 40 gigabytes of report databases.

    Now it was brought to their attention that there are several clients with half a terabyte of data.

    Also you need to have vCenter and vSphere Standard or higher in order to do Storage vMotion. Just using ESXi to move the VHDs around will be a real pain.

    By the time you get there you may or may not want to look at multiple SANs and/or hyperconverged storage.

    Local storage is fine for small shops.

    you're writing end-user desktop software that is supposedly the highest quality

    you're writing the bit that writes the error logs
    why the fuck does it not check the logfile size?

    most people don't even have a application that could open that file

    why isn't it coded to write a circular log

    Speaking of stupid shit with log files, did you know that if any Windows Component-Based Servicing log file (C:\windows\logs\CBS\) gets over 2 GB, say from a failed windows update, when TrustedInstaller goes to turn it into a .cab file for archiving, that makecab.exe chokes and will leave behind a 100MB cab file in the C:\windows\temp\ directory. And it will keep creating those 100MB files every time it runs until the drive fills up.

    Just remember that half the people you meet are below average intelligence.
