Hello Vinod,

You can try to make an installation from the command line, you only have to indicate the website, the port, the path where the installers are located and the Web Adaptor name.
Example.
CDM <path>
setup.exe /qb VDIRNAME=arcgis WEBSITE_ID=1 PORT=443

Is the machine in question a domain controller by chance?
