Question

Karel Grulich 20

I have two brand new servers running version 2025 std.

On server DCB01 I cannot retrieve the data from DCB02 in Server Manager

and

On server DCB02 I cannot retrieve the data from DCB01.

Any thoughts on how to fix this?

All other servers I have running on the network, I can retrieve the data just fine

I found a solution to this. The value under this registry key has to be increased:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WSMAN\Client

Reg DWORD maxEnvelopeSize, increased to 8192. If the entry does not exist, create it.

(I guess increasing to 600 from the default 500 would also work but I have not tested it)

to check the updated setting run power shell:

Get-Item -Path WSMan:\localhost\MaxEnvelopeSizekb

as soon as I did this, all servers started coming online

Instead of editing the registry, you can also just use the PowerShell command (running as administrator).

Set-WSManInstance -ResourceURI winrm/config -ValueSet @{MaxEnvelopeSizekb = “8192”}

Folks should also note this command needs to be run on the target server, not the machine you are running Server Manager on.

Ending curly bracket is missing (}) in example. Add one and it works

This worked for me.

The key didn't exhist on the target server or Server Manger Machine.

I added the Key to the target server.

The PS command didn't work to check but the reg key fixed.
