Becoming familiar with the command line tools available in Windows NT/2000 resource kits can greatly reduce administration tasks. The use of tools such as "CACLS," "RMTSHARE" and "CUSRMGR" can be incorporated into batch files or scripts to automate almost any admin task.
A complete list of syntax is available by typing "/?" after the command. An example of the syntax to add a user to a global group would be: CUSRMGR -M PDCNAME -U Username -AGG GobalGroupName.
A simple batch file can be written and put in your path, asking just for username and group name, saving several clicks through the GUI. For example:
IF "%1" == "" GOTO PARMS
IF "%2" == "" GOTO PARMS
CUSRMGR -u %1 -m PDCNAME -agg "DOMAIN USERS"
ECHO USAGE: BATCHNAME [USERNAME] [GROUPNAME]
This simple batch file allows me to type from the command line, "Batchname username groupname" to add a user to a group without having to access User Manager. FYI: Command line administration reduces ACL corruption if you are running W2k for administration of a NT4 environment.
