Is that NT4 server a DC?  If so, try if `mkgroup -d' returns
the "Domaenenbenutzer" ("Domain Users") group.

I just tried `mkgroup -l' on a german NT4 Wkst and I got the group 513:

$ mkgroup -l
Jeder:S-1-1-0:0:
SYSTEM:S-1-5-18:18:
Kein:S-1-5-21-2046982008-79955350-526660263-513:513:
[...]

So it doesn't depend on the NT version.  As I already wrote, this
group exists always on all NT versions.  It's just renamed to
"Domain Users" if a system is configured as PDC.

For those who are interested.  It's a piece of code in mkgroup which
always tries to figure out the name of the 513 group when the -l option
is given.  It's different in each language and isn't returned by the
Windows local group enumerator NetLocalGroupEnum(), unfortunately:

================== SNIP =================
if (print_local)
  {
    /*
     * Get `None' group
    */
    len = 256;
    GetComputerName (name, &len);
    csid = (PSID) malloc (1024);
    len = 1024;
    len2 = 256;
    LookupAccountName (NULL, name,
		       csid, &len,
		       dom, &len,
		       &use);
    print_special (print_sids, GetSidIdentifierAuthority (csid), 5,
			       *GetSidSubAuthority (csid, 0),
			       *GetSidSubAuthority (csid, 1),
			       *GetSidSubAuthority (csid, 2),
			       *GetSidSubAuthority (csid, 3),
			       513,
			       0,
			       0,
			       0);
    free (csid);
  }
