Server Manager problem: Online - Data retrieval failures occurred

Question

Hello,

I'm using Windows Server 2022 and I have this problem: data retrieval on Server Manager.
Is there a fix for this issue?

Obs:

• this is a test lab
• all servers are domain members
• I'm connecting on all servers with the domain Administrator account.
• tested with both Firewall on and off
• do NOT recommend this workaround: delete/rename the registry keys HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Channels\xxx

Thank you.

In my case (2 x Windows Server 2022 as Cluster) the issue for "Online - data retreival failure" was due to "Microsoft-Windows-Kernel-IoTrace/Diagnostic" missing or corrupt. I was unable to open said event log in event viewer. A little bit of googling around lead me to a knowledge article from Dell: https://www.dell.com/support/kbdoc/de-de/000209937/pro-ax-650-online-data-retrieval-failures-occurred-due-to-microsoft-windows-kernel-iotrace-diagnostic-missing-or-corrupted

I followed their instructions - well almost - and issue fixed. As always: be sure to have working backups!

Solution as per Dell KB article (I changed a thing because DumpPolicy is for the cluster and thus needs to be changed only on ONE node):

Steps to disable the event log Microsoft-Windows-Kernel-IoTrace/Diagnostic:

Perform Steps 1 through 8 on ONE node of your cluster only:

1. Log on to the target server as a user with administrator privileges.
2. Start Windows PowerShell with administrator privileges.
3. Execute the following command to check the current value of DumpPolicy.
   Command: (Get-Cluster).DumpPolicy Example execution result in my environment: PS C:\Users\Administrator> (Get-Cluster).DumpPolicy
   1376850201
4. Convert the decimal value to binary. (converter tools: https://www.binaryhexconverter.com/decimal-to-binary-converter) *The following are the values ​​in my verification environment, so please use the actual values. Decimal: 1376850201 => Binary: 01010010000100010001000100011001
5. Change the 21st value count from the right to 0 in the above binary number. *The following are the values ​​in our verification environment, so please use the actual values. Current value: 01010010000100010001000100011001 After change: 01010010000000010001000100011001
6. Convert the above "after change" binary value to decimal. *The following are the values ​​in my environment, so please use the actual values. Binary number after change: 01010010000000010001000100011001 Modified decimal number: 1375801625
7. Execute the following command in Windows PowerShell started with administrator privileges. Command: (Get-Cluster).DumpPolicy= <your modified decimal number> Example execution result: PS C:\Users\Administrator> (get-cluster).DumpPolicy=1375801625 (Nothing is displayed if successful.)
8. Confirm that the changed value is output by executing the following command again. Command: (Get-Cluster).DumpPolicy Example execution result: PS C:\Users\Administrator> (Get-Cluster).DumpPolicy 1375801625
   All nodes in the cluster should now give this number on (Get-Cluster).DumpPolicy

The following is to be performed on ALL nodes in the cluster:

1. In Registry Editor, change the following registry data to 0 (disabled). Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Channels\Microsoft-Windows-Kernel-IoTrace/Diagnostic Name : Enabled Type: REG_DWORD data : 0
2. Restart the OS, Make sure the event log Microsoft-Windows-Kernel-IoTrace/Diagnostic is disabled.
