windows - Folder ACLs lockdown. Unable to take ownership

this should be a trivial issue, except this time it isn't.



I have a folder on a non-boot drive in a Windows Server 2008 R2 machine which is completely stuck. Using the domain administrator account, I'm unable to:




  • delete it

  • take ownership of it (takeown gives ERROR: Access denied!!)

  • change the permissions on it (access denied)




When checking the effective permissions it shows that:




  • Administrator (Domain Admin) has FULL permissions on the folder

  • The Domain Admins group also has FULL permissions



But in the security tab it shows that the Domain Admins group lacks the Special Permissions.




The folder does not inherit its ACLs from the parent, while its children inherit its ACLs.



The owner (which is not the domain admin but a random domain user) has the following rights on it:




  • read permissions

  • change permissions



Except that not even logging onto the server with the owner credentials will allow me to change the permissions or the owner. I always get ACCESS DENIED when using icacls or takeown.

And this really doesn't seem to make much sense to me!



Chckdsk found no issues of course.
There are no open sessions locking this folder. I tried using RUNAS, booting to safe mode, logging in as the owner.. nothing has worked so far.



Is there a way to forcefully strip away any ACL from a NTFS folder?
The content has been copied, so I'm also happy to just nuke it. But it's over 8gb of data and I'd like to get rid of it.



Thank you for your help




SOLVED!! I should have said that this folder was previously a member of a DFS replication group which went rogue. The replication group had been replaced. It left behind some leftovers in the LDAP structure which I cleaned up. But unfortunately for some reason the new replication group (which bore the same names of the old one and the same targets of the old one except for the folder in question), ketp this folder as its target instead of the new one which I assigned to it.
When I realized this I removed the server on which this folder resides from the replication group and the folder from the namespace. After doing this I was able to delete it.



Thank you all

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits,

apache 2.2 - Server Potentially Compromised -- c99madshell

So, low and behold, a legacy site we've been hosting for a client had a version of FCKEditor that allowed someone to upload the dreaded c99madshell exploit onto our web host. I'm not a big security buff -- frankly I'm just a dev currently responsible for S/A duties due to a loss of personnel. Accordingly, I'd love any help you server-faulters could provide in assessing the damage from the exploit. To give you a bit of information: The file was uploaded into a directory within the webroot, "/_img/fck_uploads/File/". The Apache user and group are restricted such that they can't log in and don't have permissions outside of the directory from which we serve sites. All the files had 770 permissions (user rwx, group rwx, other none) -- something I wanted to fix but was told to hold off on as it wasn't "high priority" (hopefully this changes that). So it seems the hackers could've easily executed the script. Now I wasn't able
