Hello @IISNET-0912

try to follow the below steps:

1) open search from your machine and type DCOMCNFG.

2) In the component service window right-click on the My Computer and select properties. Choose the COM Securities tab.

3) In Access Permissions, click Edit Defaults and add Network Service to it and give it Allow local access permission. Do the same for < Machine_name >\Users or iis_iusrs, iusr.

4) In Launch and Activation Permissions, click Edit Defaults and add Network Service to it and give it Local Launch and Local Activation permission. Do the same for < Machine_name >\Users ,iis_iusrs, iusr.

Hope this helps with your query,

Using ServerManager.OpenRemote(<server>) works as expected when I use .NET 5.0, but changing my project over to use .NET 6.0 runtime, I experience this same warning/error. I can't find any documented changes to this API, so any idea why this error occurs using .NET 6.0?

Also, I've seen the above answer posted elsewhere (although for other OpenRemote related issues). Should this be run on the local machine, the remote machine or both?
