Can’t change permissions – “The parameter is incorrect”

Ok guys, we need a specific step by step set of instructions to try and reproduce this, including exactly what OS the domain is running, what OS the client is, and exactly how you're trying to adjust permissions. No matter what I do, works just fine for me, so there's obviously something being missed here.

Grievous,

Some background of my network:
Windows Server 2003 domain.
Windows XP clients.
3 sites in different geographical locations connected by VPN.
3 ReadNAS Pro Business (one in each site). All three affected. All running 4.2.12 firmware.
Tried to upgrade one of the devices to 4.2.13. This didn't fix the issue, but device froze two nights in a row after the upgrade so had to downgrade.

Regarding step by step instructions - I can reproduce this simply following instructions on ReadyNAS website http://www.readynas.com/?p=1987
Level-3 support engineer said he could also recreate this using the same instructions. Check notes of case #12976372.
Critical step here seems to be adding "Domain Users" security group to the share. Even if this succeeds any further attempts to edit permissions on next level folders fail.

I can also recreate this without using Domain Users group is if I allow Active Directory to automatically create user’s profile folders on ReadyNAS. There is no Domain Users group in the permission list, but “parameter incorrect” error appears trying to add any additional security group to newly created profile folder. If profile folder is created manually issue does not occur even when permission list looks exactly the same.

If you still can't reproduce this there seems to be something else involved.

I have an acceptable workaround now, but it would be great if the issue is properly fixed. Especially knowing that this doesn't affect only me and your own engineers can recreate it.

Is there any way to get on a mailing list for when this is corrected? As others have stated, until this is fixed, the NAS is basically useless as the work around listed isn't a work around for us as the "domain users" account isn't involved in this situation for us either.

I've experienced similar quirks in AD administration. My config:

2 ReadyNAS 3200 units, both on the latest firmware 4.2.13
Windows 2000 domain (will soon be moving to Win2008R2)
Win XP clients

My experience:
1. I create a share in NAS per instructions found on this site
2. I use Win2000 Server, logged in as administrator to create directories in NAS-created share
3. If I try to change permissions on NAS folder and propogate down it leads to a world of hurt. Found it best to leave NAS folder "as is" and focus on permissions of directories created in Windows.
4. ReadyNAS automatically adds groups/users, "Domain Users", "Everyone", "root (Unix)", "CREATE GROUP", CREATE USER" (though some of these not immediately visible), and set to "This folder only".
5. Sometimes I want my "Domain Users" to have read-execute permissions on all folders within a share and another group to have full permissions. If I try to change the Domain Users permissions at a higher level and propogate throughout it often errors out with "parameter is incorrect." If I try to remove the "Domain Users" group and then re-add it with the permissions I want I get similar results.

My work-around for "Domain Users" issue:
1. Let ReadyNAS set permssions however it wants on it's "share."
2. Create my folder(s) from within Windows under the ReadyNAS share.
3. If I want all "Domain Users" to have certain permissions I first create a group called something like, "All_Domain_Users" and add the group "Domain Users" as a member of the group. Then I assign the group "All_Domain_Users" to my WIndows folder(s) with the required permissions and for "This folder, subfolders and files."
4. It seems that ReadyNAS will still add the users and groups it wants to add, even when I try to remove them and propogate downward so I gave up trying to change them.

I just figured the problems I was having was because we're still on WIn2000. Hope this helps someone.

I'm on XP, and we've got 2003 and 2008 domain controllers, so I don't think it's a 2000 issue.

Can we get an ETA on the release of the next firmware update that will fix this? This is causing all sorts of problems, especially for our network-based applications.

I have the same problem, on a ReadyNAS 2100 with the latest firmware. WinXP machines, Win2003 server, DHCP.

I am also having this error with a ReadyNAS 2100. I was able to do the workaround to get the permissions set, but I'm not able to reassign an owner with the user created folders.

Conn, which work around worked for you?

I removed Domain Users from the security box of the folder. That allowed me to add a user and give her full control of the folder. The user's account automatically created 2 folders (redirected desktop and my documents via group policy) within the folder I created. Now I can't take ownership of the 2 folders to give domain admins full control of the folders.
