If you need this from a local system service then you can call WTSQueryUserToken to get user token from session ID, and then use method similar to this one to retrieve a user SID (or user/domain name) using GetTokenInformation API.

You can use the WTSQuerySessionInformation function to get the Username and Domain (WTSUserName and WTSDomainName from WTS_INFO_CLASS).

This function is available as far back as Windows 2000.
