Warning event log - Resolving the identity of the domain

I believe this is related to M-Files Server trying to contact domains in the AD forest that is visible to the server. You can try if setting the following in the server registry would help.

Registry Key: HKEY_LOCAL_MACHINE\SOFTWARE\Motive\M-Files\<version>\Server\MFServer
Value name: BlackListedDomains
Value type: REG_MULTI_SZ (Multi-String Value)
Value data: List of distinguished domain names, i.e. the domain you see in the warning message

Thanks a lot Joonas it worked !

Hi Joonas, may I know what is the purpose of this setting ? What does it do actually ?

Currently, I am having the same issue as posted here - community.m-files.com/.../server-error-in-application

What if the IT team had already changed to a new domain for instance newdomain.net. Is this setting still applicable or there is something need to change from the server level which is not related to M-Files ?

It stops M-Files Server from trying to contact certain domains in the AD forest. You could add this registry setting to get rid of the errors in the logs but I don't think that's the cause for your web app problems. These errors should not prevent M-Files from working.
