we need to specify NTLM Authentication in our domain, as we need to configure an external host with Kerberos and want to avoid NTLM Traffic to that host. My planned way was to activate Network Security: Restrict NTLM: NTLM authentication in this domain is set to Deny. On my way to that i found, that PRTG uses NTLM to authenticate with WMI.
Is there any way to use Kerberos instead?
As read in this https://technet.microsoft.com/en-us/library/ee156574.aspx it is possible to set WMI to Kerberos login only, but i do not want to test this scenario as my PRTG connection would brake. In my case i wanted to only set the exception list to active and used Servers, which need NTLM for Userlogin. WMI is not on my roadmap, as this would complicate my configuration.
The manual also only points to NTLM: https://owimonitor/help/group_settings.htm#windowsconnection
Thanks in advance =)
