Microsoft Server serves as DNS & DHCP.along with Windows AD+Windows MS Exchange+Windows MSSQL + Windows IIS
Nxlog Utility needs to be installed on the Server with the required privileges.
The NXLog configuration file is comprised of blocks and directives. Blocks are similar to XML tags containing multiple directives. Directive names are not case-sensitive but arguments sometimes are.
Ref. link: https://docs.nxlog.co/userguide/configure/overview.html
...
This is a sample configuration file. See the nxlog reference manual about
configuration options. It should be installed locally
Please set the ROOT to the folder your nxlog was installed into, otherwise, it will not start. Additionally ensure that some of the place holders are updated for your environment. Examples of a place holders are CCE_IP_ADDRESS, filenames for logfiles to read from.
