Hi,
Can you access \\chs-s1dfscg-001\dfsmev folder with Explorer?
Also I would like to know if all folders are created before trying to create the namespace server.
Please delete any created folders when you creating the namespace server. Let's start from begining and try to use Powershell to do these steps.
mkdir X:\dfsroots\dfsmev
new-smbshare -name files -path X:\dfsroots\dfsmev
new-dfsnroot -path \\domain.com\dfsmev -type domainv2 -targetpath \\chs-s1dfscg-001\dfsmev
