For those seeing this post and having a similar issue. I had to add in a search domain to the DNS entry under [Interface] on the client or client config file before sending it out So instead of: DNS = ADDNSIP, 1.1.1.1 I made it this edit : DNS = ADDNSIP, 1.1.1.1, localdomain.tld *ADDNS = Put in your internal dns server ipaddress*localdomain.tld = Put in your local domain name
Windows Server 2019 warns No Internet Access after AD, DNS and DHCP setup
Use the bellow command to fix this isue sc config nlasvc depend= DNS It overwrites all dependencies the service currently has. So if you want to add and not overwrite the service’s dependencies list, a solution would be first to get the dependencies list, running this command: sc qc nlasvc That outputs this: SERVICE_NAME: nlasvc TYPE : 20 WIN32_SHARE_PROCESS START_TYPE : 2 AUTO_START ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : C:\Windows\System32\svchost.exe -k NetworkService -p LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : Network Location Awareness DEPENDENCIES : NSI : RpcSs : TcpIp : Dhcp : Eventlog SERVICE_START_NAME : NT AUTHORITY\NetworkService Then run this command to add DNS: sc config nlasvc depend= NSI/RpcSs/TcpIp/Dhcp/Eventlog/DNS
Autodiscover, Office 365 and root domain hosted on Bluehost or other cpanel hosts.
The temporary workaround for windows and Outlook was to use the registry hack bellow, but I had Mac clients in the same office Outlook 2016: Exclude the root domain from Autodiscover lookup in Outlook Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur. To prevent Outlook 2016 from using the root domain of the user’s SMTP address to locate the Autodiscover service, set the ExcludeHttpsRootDomain registry subkey to a value of 1. To do this, follow these steps: Open Registry Editor. Locate and then click the following registry subkey:HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Autodiscover On the Edit menu, point to New, and then click DWORD Value. Type ExcludeHttpsRootDomain, and then press Enter. On the Edit menu, click Modify, type 1 in the Value data box, and then click OK. Exit Registry Editor. What I had to do on Bluehost was go into cpanel, to mail routing and change the setting to remote mail exchanger, then I had to open a terminal and add the snippet bellow to the top .htaccess file under the www/public html directory RewriteEngine OnRewriteRule ^autodiscover/autodiscover.xml$ – [forbidden,last] This seemed to fix the issues for both the Macs and PC’s grabbing on to the wrong autodiscover.xml under the root domain instead of from Microsoft 365
Yes! Macs Have Fewer Viruses. Here’s Why.
Apple Macintosh computers are well-known for having fewer viruses and malware than their Windows counterparts. Partly this is due to the inherent security of the Macintosh OSX operating system. And, partly it is due to the much larger size of the Windows market. Like legitimate software companies, virus creators want to reach as many “customers” as possible, and they find it more efficient to target Windows users. There ARE three other reasons Macs get far fewer viruses and other forms of malware: passwords, sandboxing, and the app store. Mac users are asked to enter their passwords to change operating system functions. It’s more difficult for bad actors to get in the machine and affect system functionality. The Mac also is designed so that applications are “sandboxed.” Sandboxing means that applications run in such a way that they are isolated from operating system resources. This makes it difficult for a virus to affect other parts of your computer system, limiting its ability to spread. And, last but not least, many of the apps on a Mac come from the app store, where they undergo company inspection and automated malware scanners. By contrast, Google Play, the Android store, has been plagued by applications that contain adware and viruses and have been downloaded millions of times. Additional SecurityRecent iMacs and Macbooks include the Apple T2 chip. This custom chip makes possible Touch ID, secure boot, and encrypted storage capabilities. So, when an Apple user uses Apple Pay, or uses her finger as a passcode, the information is safe from prying eyes. In addition, all Apple models include Keychain (found in your Utilities folder) for storing passwords and secure notes. This information is protected by 256-bit AES encryption. That means that unless you give someone your computer password it would be very difficult for the passwords that you save when using Safari, for instance, are extremely secure. Software UpdatesFor all computer equipment, including Mac and Windows software, updates are crucial. When you receive a software update notification, we generally recommnd that you accept the update with a click and it will download automatically, Mac OS checks for updates daily. You should also keep all Windows updates current Mail and DownloadsInnocent-looking files downloaded over the Internet may contain dangerous malware in disguise. Files that arrive using Safari, Mail, and Messages are screened by Apple to see if they contain certain dangerous applications. They alert you with those popups you see sometimes that will ask if you really want to open the file in question. Google Mail, Outlook, and Office 365 take similar precautions.

What To Do When Your Internet Fails
There are many reasons you can lose internet access. But only one right response: Don’t Panic. Ninety-nine times out of a hundred there is a simple quick fix. You can always call your friendly KlearLogic tech support, but the following steps may solve the problem quickly. The first step is to check if internet is working on other devices in your office or home. If it’s just your device then the problem has nothing to do with your service provider or your modem. That is often a good thing, so don’t despair. If your computer or device is the only one that is having problems you can try two things. Assuming you are using a wireless (Wi-Fi) connection, try toggling your Wi-Fi on and off. On a Mac computer you can do this by going to Status Menu Bar in the upper right of your Mac desktop. If you don’t see the Wi-Fi icon there, you must open System Preference/Networks and choose the option to display your Wi-Fi status in the menu bar. It’s toward the bottom of the Networks screen. This is a good idea anyway. If your Wi-Fi is having problems the status menu will display a grayed-out or flashing icon. On A Windows Device Locate your Wi-Fi icon in the System Tray of your windows device, located in the lower right of the screen. Today this is called the “Notification Area.” Poetic, right? Right-click it to see if you are connected to the proper Wi-Fi device. If All Devices Are Down What about the case where none of the devices in your office or home can reach the internet? If that is the case, then you will need to reboot your modem and router. If you are in a small office it is smart (and courteous) to ask any users of services or other networked data to log off or stop work because you are shutting down Wi-Fi. Turn the modem and router off for at least ten seconds. You should also unplug them from power for ten seconds. This forces your devices to make a new connection to your internet service provider. You should reboot your computer at this time, too. Give your modem 30 seconds to two minutes to finish rebooting and reconnect the devices in your home or small office. Is everything working fine? Great. If not, then there are at least two options: your connection settings are somehow really screwed up, or there is possibly an outage with your service provider If you’re in an office building one low-tech way to check is to go to the office next door and see if nearby offices are also experiencing issues. That would definitely indicate a problem with your internet service provider or some local issue like electrical problems in the building (rare, but it happens). You also should bookmark software tools that detect outages, including service notification pages for your internet service provider. Use your phone to access them when your computer can’t connect. Here are some typical ones for southern California. Spectrum Xfinity ATT Frontier Internet Settings If that’s not the problem you’ll need to double check your internet settings. But before you try that, make sure you’ve installed all available upgrades for your operating system from Microsoft or Apple. And, install software upgrades for your modem and router. Often, this will take care of the problem. Updates will get rid of bugs and security vulnerabilities that have emerged since the last time you checked, so they’re worth installing regularly. Overheating If none of that works you should also check for overheating. Overheating can cause any computer to fail and your router is a computer, too. Your router and other devices often have vents that need to be unobstructed for maximum airflow. Make sure they are clean. Distance It’s possible that your Wi-Fi network just isn’t carrying far enough—which will be obvious if you suddenly lose signal as you walk from one room into another. Try repositioning your router in the house if you find your connection is often dropping randomly. Keep any other wireless devices in the home such as baby monitors and microwaves, or office devices far away from the router if you can. The use of Wi-Fi repeaters, wireline ethernet adapters, and other solutions will be addressed in another article.
