Sometimes, when you tried to open PST from Outlook, it can occur that PST is corrupted. Outlook will get restarted and it will try to repair PST, but it is not always successful and some PST can remain corrupted. At this point Outlook will try to repair PST always on start, but if the first attempt failed, it will fail also the second, third, … Outlook will try to repair this PST even in case you delete PST from disk. The reason is in registry key where Outlook record action to take and the last corrupted PST. Now that you know this, it’s very simple to solve this problem: open regedit.exe, navigate to HKCU\Software\Microsoft\Office\16.0\Outlook\PST and change the value of the key PromptRepair to 0. Start Outlook and it will open normally – without trying to repair the corrupted PST. If you still need to repair PST, you have to find software like Stellar Repair Tool for Outlook or something similar on internet.
Yes, in some cases this can be a problem. As is true, that if you are connected in remote to a computer, you can just press CTRL + ALT + END and start a new window in Task Manager, this becomes more difficult if you are remote connected in remote session. In This case this shortcut will not work. Well, the problem is pretty easy to solve: Run PowerShell as Administrator on some other computer and find the session ID with command: QUSER /Server:ServerName You will see all active connections and here you will find also a SessionID for the connection that you want to kill. Now you know your SessionID and finaly you can kill the connection. This can be done in two ways: – As command in CMD: logoff Your_SessionID /server:ServerName – In PowerShell: Invoke-RDUserLogoff -HostServer ServerName -UnifiedSessionId SessionID Well, now you lose your session and if you will connect to that server, you will have a new session with your CMD window opened.
If someone has a problem with activation of Windows server 2019 Standard Evaluation edition, maybe I can help someone with my post. When I tried to activate the server, I received the error code 0xC004F069. Searching for this code on internet, I received many explanations like problems with KMS server, not accessible thru internet and so one. Of course, no one of this errors was the right error and I had to do my research. The problem in this case is Evaluation edition and you have to solve this issue as first. To do this you have to change the scope of server using DISM command: DISM /online /set-edition:serverstandard /productkey: N69G4-B89J2-4G8F4-WWYCC-J464C /accepteula – this key is GVLK Key! This example is for Standard edition. Be aware that as product key you must use GVLK Keys! If you need to know to which edition you can change, use the command Dism /Online /Get-TargetEditions before you specify eddition in previous command After this (you will see a progress bar with installation) you need to reboot the server. When the server will come back, you can activate it with your key: Slmgr -ipk:YOUR-KEY Slmgr -ato Hope that I helped someone. Let me know.
If you are using HTML5 web site for remote apps and you have to change a certificate, you may expect some problems. This technology is pretty new and there are not so many posts on internet, so troubleshooting could be difficult. In addition, you have more technologies and this means more problems. I adopted HTML5 long time ago and everything worked fine for a long time. I have to say, that it was better that I expected. But now I have to change the certificate. Well, this is not a complicated job… or it is? The answer is yes, it is. I have changed my certificate as usual, form server manager. I tried to connect to website and everything was OK. Then I tried to launch an application and I got this error:
Wow, what to do now?! I remember that when I setup web client framework, I had to run PowerShell cmdlet to register the certificate. So, if I had changed the certificate, I have to register a new one – rerun PowerShell cmdlet —— . This apparently didn’t solve my issue because from my computer it seems the situation haven’t change. But then a customer tried to work from a new computer and it worked! Why??? The reason was in cookies and cache files on the computer browser! Yes, you have to delete all cookies and cache files and (at least in my case) the webpage will work again.
In past I already wrote about resetting Administrator password in this post. That was perfect for Windows 10 (till 1903) and Servers 2012 and 2016. Probably Microsoft was not really satisfied that users were able to “recover” lost passwords in such an easy way (this is my opinion). It is OK if these steps are used to reset your lost password, but not if you use them to reset a password from a stolen computer.
I think that this is the reason that you cannot rename cmd.exe in other executables and run it before you log in – for example to change the password. It makes sense, it is perfect for me as it is more secure. But someone forgot something: it is not a requirement to open CMD to use NET USER command, you can do it from PowerShell as well – and it’s working also in Server 2019!
Here are the steps (they are very similar as previous steps):
Boot from DVD – you need to access to Windows system drive offline – installation DVD has all tools that you need.
From menu select Repair your computer. This will give you the ability to change some files.
In the next menu select Troubleshot.
Select Command prompt. This is what we need – we want to modify some files.
Now you need to replace the file:
Go to C: (supposing that C: is your system drive)
Type cd \Windows\System32 – to enter into the folder
Type ren osk.exe osk.old – be smart, you need to preserve the original file and put it back at the end of the process! If you don’t replace it again it means that you leave open a surface attack!!!
Replace the file with a copy C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe osk.exe
Reboot the server in normal mode.
From the logon screen choose Onscreen keyboard (as in picture).
PowerShell window will be opened – and you are a local system user!!! You can do a lot of things.
Change the password with command Net user Administrator Password – where Administrator is the username of local or domain administrator and Password is the password that you want to set.
Login to server with the new password – just to test that it is working.
Reboot the server and redo all the steps from 1 to 5, but in the way to put back all things in the original state. You need to replace original onscreen keyboard:
Go to C:
Type cd \Windows\System32
Type del osk.exe
Replace a file with ren osk.old osk.exe
Reboot the server.
That’s all. I recommend you to disconnect the server from the internet in the time you are doing these steps. In the same way you can access to the PowerShell window, it can be accessed by anyone who can see logon screen!
