NET GROUP & DSMOD GROUP commands?

[cpjust]

Hi,
I'm trying to add users to a group using NET GROUP but it keeps telling me the group doesn't exist.
I have a group called "Dom_UNIX" and when I do:

NET GROUP Dom_UNIX

it should print out the users in that group, or when I do:

NET GROUP Dom_UNIX User1 /ADD /DOMAIN

but both say:

The group name could not be found.

I also tried the DSMOD command version with:

dsmod group Dom_UNIX -addmbr User1

but it says:

dsmod failed:Value for `Target object for this command' has incorrect format.

What's going on?

Some more info...
I just realized one thing. When I ran NET GROUP, it displayed some groups but not others. All the groups that were displayed had a type of "Security Group - Global", but my groups are "Security Group - Local Domain".

Can I add members to a "Local Domain" group on the command line?

OK, I found there's also a NET LOCALGROUP command to make that work.
Is there a way to get DSMOD to work with a local group?
