See here for a good answer:

The best way to resolve display username by SID?

The gist of it is this bit:

string sid="S-1-5-21-789336058-507921405-854245398-9938";
string account = new System.Security.Principal.SecurityIdentifier(sid).Translate(typeof(System.Security.Principal.NTAccount)).ToString();

This approach works for me for non-local SID's over the active directory.
