Set SmbServerConfiguration The specified service does not exist

After I graduated with a masters in computer networking 3 years ago and I started working as a software developer for a storage solutions company where I gained experience in developing drivers for iSCSI, FC, SAS, NVMe and testing them as well. Now I want to work towards becoming pre-sales engineer for storage/cloud solutions. First off is this a good move ? What will it take for me to get there ? How can I go about adding those additional skills to my pocket?

Not sure if you guys knew but Microsoft dropped support for SMBv1 in Windows 10 1709 update. Is there a way to re-enable it? Some googling pointed me at the powershell command

"Set-SmbServerConfiguration - Enable SMB1Protocol $True"

But this is not working git tells me the specified service does not exist. Does anyone have a solution / workaround for this?

Hello.

Situation looks like this:

BRAS ----------- SWITCH ------------- PC (Windows)

BRAS is set to send an LCP echo request every 5 seconds. If 20 LCP echo requests get no reply the PPPoE connection of a client is terminated.

The PC is running Windows 7/8/10, has a PPPoE broadband connection added and is running.

Scenario 1) I drop all frames with an ACL rule on the switch port facing the Windows PC to simulate a connection failure (without the ethernet ports going down).

After 100 seconds the BRAS terminates the PPPoE connection on its end.

While looking on the PC's Wireshark traffic it seems that the Windows PPPoE driver does not send any LCP echo requests right away on its own so it doesn't detect that the link is down in a reasonable timeframe.

After 4-5 minutes since the ACL rule is in place on the switch Windows sends an LCP echo request every minute 3 times - then it terminates the connection. Good, but this is WAY, WAY too long.

Is there any way to configure it?

In the meantime the connection on the Windows' side remains active until it gets terminated after (8 or so minutes) which is misleading and untrue.

If I could get the LCP mechanism to be more aggressive I could script it with a Task Scheduler based on the disconnected event to try to reconnect automatically.

Of course I realize I can take just about any consumer grade router and set the PPPoE connection there and it would work as expected, but this is a situation where I cannot plug anything else.

Thanks.

I have a task to visually map a domain, which contains over 170 groups some of which are nested. There is no previous documentation, don't ask why.

Is there any kind of software or script which could do that? Output could for e.g. be for Visio or something similar.

A lot of our Amazon EC2 instances do not have Elastic IP's, which causes issues for external vulnerability scanning, as the IP addresses are dissociated with the instances whenever stopped, terminated or restarted.

I'm curious how other organizations deal with this issue? I'm thinking about requesting/suggesting that an Elastic IP is associated with every externally facing host in our Amazon environment but i'm not sure if that's a reasonable recommendation?

I'm having an issue that I'm looking for some ideas on. I have multiple offices with brand new CradlePoint 2100s with Verizon modems. I'm getting random router reboots (once a day or so) from a few of the offices. It used to be much worse when the LAN/WAN ports on the 2100 were auto detect. since changing to 100FD the frequency of reboots, especially at one office, have drastically gone down but yet still happen. These routers are all running the current OS just released (6.4.2). We certainly aren't overwhelming the routers with crazy packet counts or anything. CPU throughout the day is under 10%. We are running ECM with the overlay only for device administration. We also run DM VPN between multiple offices.

CP support has been pretty good so far but they are saying the next step is turning off the LAN to see if it reboots but the reboots are random enough that it isn't going to tell me anything if it doesn't reboot. also logging to USB sticks doesn't tell what service is causing the watchdog to reboot the device. If I disable watchdog reboot, I've had hung routers as whatever is causing the device to reboot is hanging the router. I have RMA'ed and rebuilt configs from scratch with CP Support multiple times.

Any thoughts? Any help would be beyond appreciated.

Does anyone know if a microsoft RDS license is required to run a persistent VMware Horizon desktop?

I know its required for citrix xen desktop because that utilizes terminal server however vmware horizon runs over PCoIP which is independent of that so i dont know if RDS license is required.

My organization has been running Sage 100 ERP for nearly 7 years (currently on the 2017 release), and by and large it's been good and suites our needs. But still, there are some quirks and things about it that just make me scratch my head. The latest thing: printers.

Side note: I hate printers.

I recently moved us from a single 2008 R2 RDS server to a load balanced 2 machine Server 2016 RDS farm. Each printer has its own Security Group and people are added to the groups as they need access, and then the printers are deployed from Print Management via Group Policy from a Server 2012 R2 print server with all drivers coming from a central repository. Permissions to the printers are set from the print server. Printers are a combo of Ricoh multi function, HP LaserJet desktop, and Zebra thermal label printers all running a consistent array of drivers. Printer redirection is disabled.

When employees' log in to the RDS farm, their printers are all installed right away and they can print from Word, Excel, BarTender, etc. without any issues. The printers all show up properly within Devices and Printers as well as the new Windows 10/2016 Printers menu. Their Default Printer is set properly. Still, sometimes when they log in to Sage 100 they will either have no printers, all printers, or a random assortment of the printers they should have. Log out of Sage 100 and back in, and sometimes you get the same results, sometimes you don't.

WHY!? I do not know. I am determined to figure it out, but the fact that every other application works fine other than Sage 100 makes me angry.

Cheers!

At our place, we haven't reinstalled the operating system of the workstations for a good while, unless there is a specific reason for it, like virus infections. After a suspected virus infection on a workstation and a precautionary reinstall yesterday, our CEO asked if we have a plan for regular reinstall of the machines. As we currently don't have such a plan, I was wondering what sort of policies you have on this?

A complete reinstall would last year be a nightmare, with a windows cd/usb stick, and many days of walking from machine to machine to install OS, install update, install programs, join AD etc. You know the drill... Luckily, we now got WDS/MDT, and it works great, but we haven't tried a massive reinstall yet.

So how often do you reinstall?

EDIT: The consensus is no periodic re-install of the OS. Re-install on virus infections, non-recoverable errors, changing owners, switching roles, et cetera is on the other hand expected.

So we have a hybrid server for 365 on prem. We use it primary as a relay for internal stuff. I notice in log parser odd emails or people sending emails from "not our domain". I'm posting a snippet. Does this mean external folks are actually using our hybrid as a relay? I thought we had it locked down, but maybe I missed something.

I just wanna nip this in the butt soon if thats the case. Our hybrid is open from the outside obviously, so I guess its possible. The crossed out emails are just the ones that initiated from internally.

Facebook is my place for social commentary. I rant about the daily happenings of my I.T. position and people generally find them entertaining.

Today, I posted a small rant about going out of your way to say "hello".

This is exactly what I typed, "Why do people go out of their way to say hello? I'm not talking about just saying hi in passing, but literally going out of their way. I'm here. Working. Alone. In the dark. And someone who works on the other side of the floor comes to my desk. "Goooood mooooorrrning". '...... Hi.' "I thought I heard someone over here. Just wanted to say good morning". Yeah, you did hear someone over here. Because there IS someone over here. I'm typing. My music is on. Yep. Definitely someone here. JFC, go away."

I got a LOT of shit from this - surprisingly. A few asking me if I was really serious. A few calling me a miserable fuck (well, I am). The only ones who understood what I was saying were those also in the I.T. field. Am I alone here? Anyone else feel that when someone pulls this crap they're trying to buddy-up so they can get special treatment later? Anyone else come in really early just to get shit done without being bothered by users?

This is probably more relevant for helpdesk than for sysadmins but I thought I'd share for those who haven't seen it yet.

  If you have any of the orange logo "Unify" Logitech devices you can reprogram them to work with any Unify keyboard and mouse, up to 6 devices can share one dongle. Using this point and click Unifying software

  So now whenever I get a PC back with a dongle and no keyboard/mouse, it goes in a bucket to be reprogrammed later. I'm also contemplating pairing a spare keyboard with a colleagues dongle for some shenanigans.

Long story short. I work as sys admin and also happen to be a HP certified repair technician. I've probably deployed close to 50,000 Chromebooks in the last 4 years and repaired close to 2,000 of them. The majority Samsung and HP with a handful of Acer and Asus here and there. Just finished deploying a batch of 4000 HP Chromebook 11 G4s. Ordered over a 5 month time frame in batches of 1000. I've found HP Chromebook 11 G4s have been the absolute worst in quality control I've ever seen in my career out of any hardware. Here is a breakdown of the issues I've found out of these 4,000. I'm only reporting below issues that are manufacturing flaws.

• 4 have caught fire after being plugged in for 15 seconds or less. Charred the port and the power adapter. Faulty part was the charge port had an excess amount of solder on the wires casing 2 red, 2 black and 1 brown all to connect to each other. All 4 serial numbers were exactly the same up to the last 2 digits. I'm assuming this was a batch issue.

• 383 with bad track pads. Most of them were fine at first but they dropped like flies. Most failed within the first 2 weeks of use. Probably only a dozen were bad out of the box. This number is increasing an average of 2 per day. That's 10 a week. HP refuses to recognize a manufacturing flaw, I keep demanding they ship me a box of 50 trackpads at a time instead of ordering 1 at a time. Still a work in progress.

• 100+ with serial/product numbers printed so poorly they can't be read. Literally just looks like a stamped white blotch.

• 74 had bad ribbon cables. After removing the shielding wrap, most cables just got twisted causing them to pull al the ends out of the connectors. Only 2 were bad out of the box, the other 16 failed within 2 months.

• 15 with static speakers. The speakers worked but there was a loud static to them. This is out of the box.

• 7 had broken displays out of the box. Not cracked, just either solid black or solid white. Replacing ribbon cable did not resolve the issue.

• 3 had bad keyboards out of the box. Not sure what causes this though. This actually is a pretty average number for a batch this size.

• 1 with bad network interface card.

• 1 with bad camera

• 0 bad chargers. Every single charger worked out of the box. So at least I have that going for me. HP G1 and G2s had failing chargers like it was the black plague. HP was nice enough to replace them even out of warranty for awhile.

This has easily been the worst quality device I've ever worked on. HP G2 and G3s probably had 1/5 the failure rate of these. In all seriousness though, I would have killed myself by now if it was more than 14 screws and 2 minutes to disassemble them completely. I have started drinking heavily though, that seems to help.

Can anyone attest to any of these? The latest posts are 6+ months old and little about Crowd Strike and ATP (new product). The posts also talk about lack of a lot of features that have since been integrated into these products

Mainly we want to know about overhead. Which of these products is the best at low overhead (small security team) but still is a good product? If it takes a small project to setup, that is fine. But overall day-to-day management, what is it like for those that do it? Is it 10% of an engineer's day, 25%? Need 1 FTE just to own the tool?

We're an enterprise of 5,000 endpoints that are highly mobile and international. We're going to come down to 2 of them and do PoC's, but are wanting to get real life opinions on which ones we should actually move forward with testing.

Please disclose the type of environment you're working in as well if you feel comfortable doing so.

God fucking dammit Microsoft, I don't want to login to view your fucking technet forums! Every time I want to follow any google link to your fucking forums at https://social.technet.microsoft.com, you ask me to login.

I just want to read, for fucks sake!

I don't want to having to clean my cookies beforehand everytime, to read your fucking forums.

Wrote an article on finding malicious chrome browser extensions as well as preventing them from being installed in the first place through a chrome GPO. Hope you find it useful as it can be a pain in the butt trying to figure out strange outbound connections sometimes.

Hi, I'm not sure if this is the correct place to be asking this, but here it goes.

I am planning to install Xen on a server we just got, it will function as a storage server and host a small website locally. It has the processing power and memory for all of that, but my question was will installing Ubuntu and FreeNAS on that cause any issues?

I just started a new company and walked into a mess. I have tried so many different ways to google this situation but I am not having any luck finding help with this same or similar setup. We have one Domain/network call it @theone.com that is the "parent" company. Then they started another company called theonefs.com. The people that work for theonefs.com logs into their computer with a AD account. The deal is they have a email address in 365. @theone.com also has a 365 tenant account. They want to merge these two tenant accounts into one. I have not found anything useful on how to merge two tenant accounts that are actually tied into the same domain. Hell I'm not even sure I am explaining it right this is so messed up.
