ERROR: same Excel file opens twice

I had a user with an excel file that when you click it to open, it opens twice:
myfile:1 and myfile:2

If you have the same file open in 2 windows, close one window (Ctrl + W) and save the remaining workbook. Reopening the saved file you should have only one instance.

Problem: orphaned OneNote Notebook still listed in OneNote Online/App

I deleted a OneNote Notebook from OneDrive and despite the file is no more there, on OneNote App and on OneNote via Web it’s still there as Notebook that I can open (and if I try to open it, I receive and error).

I fixed it by opening OneNote desktop version and going to File > Open.

Delete the notebook from the list under “Recent Notebook” (Right click the notebook and select “Remove from List” to remove it).

Now when I go to OneNote online and click Notebooks, I only see the notebooks that were left in the Recent Notebook list.

Problem: VMware Tools on Windows Server 2016

Checking on vSphere my new Windows Server 2016 VM, I noticed that there was a warning regarding VMware Tools not installed. This was not true because VMware Tools was installed on vm but checking the services, only “VMware Alias Manager and Ticket Service” was there!.

I uninstalled VMware Tools, restarted the VM and reinstalled VMware Tools right-clicking “Setup64.exe” and selecting “Run as Admin”.

Now I have all the VMware services installed and the warning is gone on vSphere.

ERROR: Task scheduler service is not available

On Windows Server 2016 creating a new task on scheduler I stumbled on this strange error: “Task scheduler service is not available. Task scheduler will try to reconnect to it.”

Task scheduler service seemed running fine (at least for other tasks :-)). After some troubleshooting I discovered that the problem was the Network condition Setting:

SchedulerTask_Network

If I define this condition, the task stop running with the error above.

Error: DCDIAG report “Invalid service startup type: NtFrs”

On a new Windows 2012 R2 Domain Controller on a 2008 forest level with SYSVOL already migrated to DFS, I had this error running DCDIAG:

Starting test: Services
Invalid service startup type: NtFrs on DCO01, current value
DISABLED, expected value AUTO_START
NtFrs Service is stopped on [DCO01]

Starting test: VerifyReferences
Some objects relating to the DC DCO01 have problems:
[1] Problem: Missing Expected Value
Base Object:
CN=DCO01,OU=Domain Controllers,DC=mydomain,DC=local
Base Object Description: “DC Account Object”
Value Object Attribute Name: frsComputerReferenceBL
Value Object Description: “SYSVOL FRS Member Object”
Recommended Action: See Knowledge Base Article: Q312862
……………………. DCO01 failed test VerifyReferences

Every thing is working fine (at least on my DC), it’s only an incorrect error detection from DCDIAG: https://support.microsoft.com/en-us/help/3110032/dcdiag-verifyreferences-test-fails-when-you-use-dfsr-to-replicate-sysvol

On the DC with this issue I had DCDIAG.EXE version 6.3.9600.16384
Updating it with KB2919355 the DCDIAG version jumped to 6.3.9600.17031

How to Disable Network Card from CMD

If you need to disable a NIC from command line on windows this is the path:

WMI:

wmic nic get name, index

Check then index of the NIC you want to disable and run:

wmic path win32_networkadapter where index=[NIC number] call disable

…change the [NIC Number] with the index of the wanted network card.

Now in the control panel, you should see that the desired network connection is now disabled.

To enable it again:

wmic path win32_networkadapter where index=[NIC number] call enable

If you what to disable some type of devices (like WiFi), type this command to check the NetConnectionID attribute:

wmic nic get name, index, NetConnectionID

WMI_NIC

and disable it selecting by NetConnectionID:

wmic path win32_networkadapter where 'NetConnectionID like "%Wi-Fi%" ' call disable

or

wmic path win32_networkadapter where NetConnectionID="Wi-Fi" call disable

All these tasks can be done with netsh or powershell.

Netsh:

netsh interface show interface
netsh interface set interface "Wi-Fi" disabled

Powershell:

Get-NetAdapter
Get-NetAdapter -Name wi-fi | Disable-NetAdapter -Confirm:$false
