windows 2012 wlst nmEnroll error while enrolling new domain

command and Windows 2012 server

nmEnroll(domainDir='D:\Oracle\app\domain\iam_domain',nmHome='D:\Oracle\app\Middleware\wlserver_10.3\common\nodemanager')


ERROR
WLSTException: Error occured while performing nmEnroll : Problem enrolling the machine. : D:\Oraclepp\domain\iam_domain\security\SerializedSystemIni.dat (The filename, directory name, or volume label syntax is incorrect)

Solution:
I Have resolved this error after looking into domain configuration file <DOMAIN_HOME>/config/config.xml

i searched my machine name that i was trying to enroll and found the path in "/" slashes instead of "Windows" "\" 
so i ran command at windows with "/" slashes and successfully enroll the domain


nmEnroll(domainDir='D:/Oracle/app/domain/iam_domain',nmHome='D:/Oracle/app/Middleware/wlserver_10.3/common/nodemanager')
