This isn't my shop internal stuff, but it's a question for a client. They are two CPAs that lease a Remote Desktop Connection to a desktop environment they run their accounting software on.

They straight up hit it via a public IP address on default port with only a user name and password guarding it. the vendor has lied continuously about how "They totally use a VPN to keep customers safe" and my people need to jump ship.

Question: What other vendor can they pay for a more secure connection? My only other awareness if RightNetworks, whom I'm not sure is any better. They'd love what they had at the place they left, which was a nice VPN tunnel that allowed RDC as well as shared drives and such.

Cloudvara is what they want to get off of.

Assuming you need to keep the server-based accounting software solution, there are plenty of MSPs out there more than willing to provide a "private cloud" solution which would provide an SSLVPN connection to them, and they'd connect and then jump into remote desktop or whatever else. Look for MSPs that specialize on the CPA space, local to you in case they need onsite support for something... On the back end it'd probably be AWS or Azure with a VPN appliance and then 1-2 servers. I'd expect such a setup to be about $1k/mo?

Our xerox photocopier seems to be screwing up the dns resolution of the office 365 smtp server about like 5-10% when doing scan to email. We have it set to use google dns (8.8.8.8/8.8.4.4) but when I ping smtp.office365.com on my desktop, it seems to lag to resolve the address. The dns records also seem screwy to me (via dig in google toolbox):

code:
;QUESTION
smtp.office365.com. IN A
;ANSWER
smtp.office365.com. 300 IN CNAME outlook.office365.com.
outlook.office365.com. 300 IN CNAME outlook.ms-acdc.office.com.
outlook.ms-acdc.office.com. 57 IN CNAME LYH-efz.ms-acdc.office.com.
LYH-efz.ms-acdc.office.com. 7 IN A 52.96.119.82
LYH-efz.ms-acdc.office.com. 7 IN A 52.96.97.130
LYH-efz.ms-acdc.office.com. 7 IN A 52.96.183.226
LYH-efz.ms-acdc.office.com. 7 IN A 52.96.182.2
Three CNAMEs and four A records??

Anyway the vendor has suggested to replace smtp.office365.com with a direct IP address - it seems to be working for now - but I hate that solution because the hostname can resolve to several different server IPs and is constantly being updated by MS.

Any of you guys dealt with something like this?

That's just the result of it resolving the CNAME to the A records, it looks the same for me:

Yeah I figured out after I posted that it's a 3 level CNAME chain that ends with four A records, I still don't really know what to do with this photocopier because I've plugged one of those IPs into it instead of the hostname (working fine for now)

It's the size of the DNS packet and the crap resolver in the scanner that bombs out if it's too big a packet. (Often happens when there's additional info tossed into the response). Usually happens when there's authority info added to the packet - which will increase the packet size to >256bytes.

3 level CNAMEs is the proper way of doing things (public name -> service load balance -> cluster loadbalance -> machines), but because of the old 256b limit, many large entities have had to fix their responses to be below it.

The quick fix was to shorten your domain name. (ever wonder why some companies have a weird short domain behind the scenes? Usually this) But these days most combine all the above into a single response (cloudflare/etc) now.

The culprit long time ago wasn't printers, but was actually firewalls that ran DNS filter proxies (no one does that any more) that had the same issue and dropped large packets.

Hi Thread! I recently fell into a position as Technology Director for a small nonprofit, ~60 users. Figured I'd come in and introduce myself and let you know some of the things that are top of mind for me. If you have any thoughts on where I should start or redirect me, I'm all ears!

  • We have no system for making sure that users are keeping their devices up to date. I think I can use our Microsoft licenses to do this with Endpoint Manager?
  • Our current process for issuing new laptops is to buy them, get them into the office, spend hours installing everything and then mailing it to the employee. I'm speaking with Dell but it looks like with Windows Autopilot I can just have Dell send someone an imaged laptop directly?
  • I've heard from a lot of people that our current laptops are crap. They have issues with MS Teams video chat not working well or at all, and some programs running so slow they can't do anything. I suspect at least some of this is due to bad higeine like not rebooting regularly and running old OS versions. but assuming I get everyone's computer up to date and whatnot, does anyone have a recommendation of a Dell laptop that they would issue to 75% of employees who just do the basic collaborating via o365 and web apps? I will have a couple of high performance needs for people running statistical analysis and some design tools but what would you recommend for 75% of generic business use cases?
  • We don't have any SSO. I'm planning on using Azure AD for our SSO needs.
  • Do windows computers need to run antivirus software, or is Windows Defender enough?

I think that's all for now. Any thoughts or reactions from you expert Goons would be greatly appreciated!

Hey! Congrats on the new gig and welcome to the thread.

  • Yes, Microsoft Endpoint Manager is a really great direction to head in.
  • Autopilot is great, but the lynch pin is always Autopilot with Azure AD Hybrid Join. If laptops need to join the domain, they will need line of sight to a domain controller when they go through Autopilot. This isn't always easy and usually involves a VPN, but there's plenty of words out there that talk about it more. Just keep in mind that this is usually what trips people up. If you can get off legacy AD and just use Azure AD (you don't have legacy apps that need access to on-prem resources), then you'd make life much easier in the long run. Just know that this differs from "images." Dell doesn't send an imaged laptop, they send a standard laptop and it gets brought up to your baseline during enrollment.
  • This is an easier question and I'm sure you'll figure it out. Any modern laptop with an SSD is likely to be fine.
  • Again, great direction. Azure AD works very well and is easy to manage.
  • Windows Defender works great. Microsoft has a whole security infrastructure built around Defender and you'll be able to do quite a bit with the entire suite.

If at all possible, I'd try to lock your department's support down two laptop models of your choosing, one for standard users and one for power users who will need more horsepower, then do not deviate from those two models. That will cut your image management down to two images, which will make your life infinitely easier.

The "standard" model should be easy enough to choose. For your power users, I'd recommend speaking to all your power users to make sure whatever upgraded model you choose for standardization will be sufficient for their needs. Then decide how many years you want to go between manual computer refreshes. You will need approval from the brass to do this. For the inevitable presentation you'll need to make to present your case, study up on the statistics regarding how much more expensive old computers are to maintain (including cost of work for lost productivity during outages, which older computers are much more likely to face) than new computers are to cycle through every several years.

Believe me. I've worked at companies that do the onesie-twosie dance with laptops (somebody needs a laptop so you're supposed to hop online, go to any old vendor, including ebay, and just find whatever is cheap that day and buy it, then be expected to support it forever) and it just makes the job excruciating. And as a bonus, you end up with closets upon closets of old PC's that maybe do maybe don't work or maybe are maybe aren't new enough to redeploy. Avoid that at all costs.

Adding to the already great advice you've gotten above, I'd say make sure you standardize on business-line laptops, with good warranties. There's a distinct quality difference between home and commercial laptops, and getting good warranties so you don't have to worry about hardware failures will pay invisible dividends in terms of avoiding lost work and IT reputational damage. Lean on your non-profit status with vendors to get whatever discounts you can. I don't know if TechSoup is still a thing, but look into that (or its successor). And congrats!

I had two users batteries "die" (instant 0%, not charging) at the same time last week, both have been running laptops off the DC power adapter and of course both are fully remote WFH 20+ hours away. It looks like both got pushed a windows update about that time but rolling back didnt help.

...Dell apparently decides to throttle the CPU down as much as possible to 22% max frequency due to that perceived missing battery.

Did this happen to anyone else within the past few months?
Anyone know of a way to force a Dell XPS 15 on Win 10 out of a power/battery saving mode?

EDIT: I was able to force the clock speed to 100% by editing the registry, just need to figure out the battery issue but at least the show stopper is resolved.

Basically you're delivering email directly to ms365's external server like a normal spam message. It'll get scanned like normal mail, so you'll have to do some tweaks in your exchange setup so the external IP it's coming from passes or something.

This way you don't need a license. Also, MS is trying to get rid of normal/plain authentication on pop/imap/smtp eventually so 2FA actually works.

That article has been the gold standard for years, yeah.
It is 100% only useful for mail that stays in your org, and you need to have the locations using it set in your SPF record, as unknown said, but it's amazing at what it does.
Doesn't matter what you put in the reply to address, doesn't even have to be an address that exists, so long as it's in your tenant.
Mostly it's meant for stuff like scan to email, email alerts from legacy systems that stay in org, that kind of thing. It's absolute magic for its use cases.

This isn't 100% true, you absolutely CANNOT use an address that exists as a user.

Office 365 question - I'm implementing Security Defaults for my organization, but after I turned it on I realized that users can't select SMS/phone call as an authentication method.

We like the idea of Security Defaults because it gives users a 14-day grace period to sign up for MFA instead of instantly locking them out until they sign up. However, some users don't have the option of a smartphone app to log in, so they'd need a phone call or SMS code. I know that's not the most secure for those users but, well, here we are.

Is there a way to either use Conditional Access and gives users 14 days to sign up, or turn on SMS along with Security Defaults?

This is probably true, I've never tried to use an existing address as the reply to.
Now I want to, to see exactly how it breaks.

As you said, Yubikey or another passwordless option, hardware TOTP Tokens such as https://www.microcosm.co.uk/order/product.php?ProductID=346, or any authenticator app. SMS is a crutch and we'd probably all be better served if MS just disabled it as an option.
