Reverse DNS records on the public DNS need to be added by your ISP that owns the IP address. PTR records added to your windows DNS server are typically not accessible on the public internet. Windows DNS is not typically your authoritative DNS server for your domain or PTR records. Windows DNS is usually used to host internal (to your LAN) DNS records and ...

Try CTRL-SHIFT-ESC instead of ALT. That directly opens Task Manager instead of going through the CTRL-ALT-DEL screen first. Works for me on a nested core RDP session as long as both sessions are configured to send Win key combos to the remote session.

Okay, finally we found the reason: After we hired an external specialist we found out that the on-board NICs are physical broken. After installing a PCI network card we were able to get network access back. We updated the BIOS, all drivers, used an usb-boot-stick - none of them were able to reactivate the NICs... Fortunately the mainboard has a guarantee ...

Because it's just the index, you can repair this by performing an offline defragmentation of the Active Directory database. This will drop and recreate the index. Only cost me a 3 minute outage. Clone and test if you can. https://asknicks.blogspot.com/2013/05/active-directory-database-corruption.html See MS article KB232122

you need to browse to the AAD Connect folder in program files in powershell and run Import-Module .\AzureADSSO.psd1 then run update-AzureADSSOForest enter your domain credentials. Once this is done then launch AAD Connect and you will be able to enable. This happens because the server was already associated with SSO

It depends on the storage array you've got in mind. A passive SAS enclosure (usually with an integrated expander) requires a SAS RAID controller. A SAS array requires a SAS HBA (it uses the RAID functionality inside the applicance). Both are Direct Attached Storage/DAS, but can potenially be shared across hosts when they feature multiple host ports or ...

We solved it by performing a full restore to a 20-day old Acronis backup, then restoring AD to a current backup. As commenters noted, having a single DC is risky. We will be converting the server to VMware ESXi and running 2 VM DCs, as well as other VMs to run other non-AD services, to reduce these risks. Thanks all.

After wasting a week and loosing lots of money, stumbled upon this tutorial which dates back to 2012. https://github.com/SignalR/SignalR/wiki/Performance Apparently there's a ridiculous 5,000 limit on max concurrent requests per application that IIS handles. So I ran the command below at %windir%\System32\inetsrv\ changing it to 50,000. appcmd.exe set ...

This is your problem: Remove access to use all Windows Update features **Disabled** Contrary to all common sense, this setting disables access to Windows Update if it is configured, regardless of whether it is set to Enabled or to Disabled. Set it to Not Configured and your problem should go away. On Windows Server 2016, you can make the change ...

You tagged your question credentials, so if you need to supply a SecureString as a parameter somewhere, you should use the Get-Cred command. To get just a simple string, use Read-Host. However, I personally find scripts that use Read-Host and Write-Host (and even Get-Cred) to be painful to use. You SHOULD be writing scripts to accept parameters. Then your ...

I only have access to one Windows Server, but managed to rehearse the 'server won't boot but can only fully read user files from Server Backup via 'Windows Backup tool' on a server' conundrum by downloading an evaluation copy of Server 2019 Essentials from the Microsoft Evaluation Center and spinning up that 6-month trial copy in a Virtual Machine (in my ...

Merging a delta disk like this is I/O intensive. Read source volumes, read checkpoint, write to target volume. I don't know the exact block size, but it could easily be doing a thousand random I/Os and taking seconds on that storage. Experiment on faster storage that does many more IOPS. Also store checkpoint and replication target disks to be on a storage ...

This issue happen when the winlogon service can’t handle gracefully the user login. Check list to check: GPO that utilize a lot of the server CPU. A good exemple is printer mapping if you don’t use by default the Easy Print driver, as the spooler will take huge chunk of CPU to connect the user. Clogged profile; make sure the user profile is not locked up ...

This is how I've done this in the past. I have had a lot of success with this with no issues in Windows, but please note YMMV: Boot the computer with a Windows Installation CD. Choose "Repair my Installation" and then choose "Command Prompt" Navigate to different drive letters (e.g. c:, d:, e:, f:, etc) to figure out where your current Users directory is ...

The above answer usually works, I'm leaving this here in case you can't access the Lifecycle Controller for whatever reason. You can download the driver from Dell's website, in your case: PowerEdge T640 In the case of Windows Server 2016 the package would be: Windows Server 2016 64bit driver for PERC S140 Controller Also, make sure the drive has been ...

Use the Lifecycle Controller to install the operating system. It will inject the drivers that Windows needs to find the hard drive.
