ECHO List all members of the specified group(s), users as well as nested groups.

:: Pipe symbols cannot be ECHOed in Windows 9x, so in that case

:: we need to use an alternative character (like ASCII 179)

IF     "%OS%"=="Windows_NT" ECHO Usage:  GRMEMBER  group_name  [ /B ^| /G ^| /U ^| /V ]

ECHO Where:  "group_name" is the name of the group to be queried

ECHO         /B           lists both users and groups (default)

ECHO         /V           lists both users and groups, same as /B

```
ECHO.

ECHO Notes:  Nested groups are marked by an asterisk.

ECHO         This batch file uses DSGET and DSQUERY (native in Windows

ECHO         Server 2003, will work in Windows 2000 and XP if available).

ECHO         Increase DSQUERY's "-limit" value for networks where groups

ECHO         may contain over 10000 members.
