I just got my new Dell running Vista. I got it all set up and the last thing I set up was my backup routine. I have another desktop running and store all my information (music, pictures, TiVo and backups). I have struggled to get this to work. I continue to get "No mapping between account names and security ID's was done". I have searched and set up everything I know, but I can not get pass this point. I gotta believe that it is on the Vista side as I have add no problem with XP Home or XP Premium... Any ideas? Thanks, Mark

I get that error or that I'm using the wrong logon id and password which I'm not. It can browse to my share yet when I try to setup VIsta backup there it says invalid id or password. Also, when I try to image my machine using Vista I can't do so to a network share. This version of backup is actually worse than previous versions. I would have been happy with what came with Server 2003 Small Business Edition.

Here is the exact error message that I get when I point the Vista Backup Files to a network location that Vista see's fine UNTIL it goes to test the location. The network share could not be accessed for the following reason: Logon failure: unknown user name or bad password. (0x8007052E) Please ensure that the network location is valid. So, something that is already authenticated wants to be authenticated again, using the logon id and password for the device gives this error even though Vista see's it just fine. I tried setting up Windows Live OneCare's backup to this location, it mapped and tested fine. So, OneCare has better support for this than Vista itself??? UGH!!!!! I have signed up for the Windows Home Server beta, I'm hoping my Buffalo Terraserver works better with that than it does with Windows Vista Ultimate.

I have the same error with WD netcentre. I pluged in my printer too so my Daughter can use it. The back up does not work at all. If I install Windows one care live the back up in that soft ware finds the drive just fine, but its far to buggy to rely on full time. I spoke to a Microsoft rep on the phone and he could not sort out this problem. Seriously considering going back to XPpro.

New HP vista machine won't play nice with existing 2000/Linux network. I can see the Vista Machine from both the Linux and 2000 machines and I can see the networked machines from Vista. I've setup identical accounts on the target machines and the Vista machine. I can navigate through the Vista backup process but when I attempt to logon to the destination machine I get the error.Definitely not impressed with Vista and Vista Help.

I also am experiencing the same problem. I tried setting up a backup over my home network to an XP PC. I can access the PC files just fine using Windows Explorer. But when I try to select a path on the PC using Backup, it keeps asking for a username and password. But I don't have a passwords setup. It looks like a bug in the backup program that it doesn't work unless the share is password protected. How can we alert Microsoft to this issue so we can get it fixed? To work around this, I setup a user with a password on my XP PC. But then I get the following error: You need Full Control permission for the network share. Make the user a co-owner of the share, with Full Control. The network share cannot be on a computer running Windows XP Home (0x8100002A) My XP PC is the Home version. Why would this not work from an XP Home machine? It's just a file server. So what's the deal here?

I have exactly the same message with XP Professional as the target for the backup. On top of this, my tape backup cannot be seen by Vista backup, so both parts of the D2D2T fail under Vista. Very disappointed.

Same problem here with Dell also. Any chance this will help. http://www.pcreview.co.uk/forums/thread-307444.phpI know its for XP but it seems similar. HELP...FRUSTRATED!

I've been in contact with Buffalo Tech Support, but they could only suggest the registry fix (see Buffalo site) and that did not help resolve the problem. I plan on contacting Dell next week and letting them know they should not sell this product with Vista based machines since Buffalo Tech seems unwilling or lacks the knowledge to fix the problem.Yes, a USB device would have much better than a NAS device running an old version of SAMBA. - Greg

Greg - I've been working with the help desk at Dell; most of last week... They tried and tried and finally escalated up to their tier one group. Anyway, the bottom line is that, at least what they told me, was that this version of backup and only backup to another Vista machine. Okay, Ill buy that; at least until I can test it against another Vista machine. Ironically, I can pull the backup from my XP machine, but I can not push the data from my Vista to XP. Im okay with it for now. I just VPN into my XP and launch the backup application and it is done Mark

Bump any more info on this please.

I've been struggling with these same issues myself. It's extremely frustrating and irritating that MS not only dumbed down the backup tools but then as a real slap in the face they broke it to the point that it's not even functional for anyone who wants to back up to anything other than a hard drive that is always in an "on" state. I have had the backups fail to both a Samba share that works flawlessly for everything else, as well as failing to an ESATA hard disk. I suspect that the ESATA failures are being caused by the drive going to sleep or a low power state but I'm not really sure (haven't had time to check it out). With Samba I am really at a loss. I suspect it just doesn't work properly. I have the Samba share mapped, but the only way to specify the backup in Vista is to put in the netbios path. After doing this successfully the Backup Wizard re-prompts for the login/password to the Samba share and even though the login given has full permissions on that share in Samba, the Backup wizard comes up with a complaint about the user not being an owner, or it complains that the "path specified" is invalid, or several other things. I have one user that (for whatever reason) the backup Wizard accepts, but when the backup runs, it gets through making some of the directories and then fails. It's really irritating. Additionally the backups are done using "backup" permissions, but there's no way tomanage the backup files (such as simply copying them to a network share a la Robocopy)because in Vista Premium there is no group control so you can't add your userid to the Backup group to copy/move the files at will. The more I have used Vista and the Backup software the more I realize that MSFT thinks we are idiots. You have to turn off UAC or buy the Premium version (extra $150) just to get features present in XP Pro. It's rather disgusting actually.

I was finally told by the Dell Help Desk, after they escalated this up the ladder that the Vista backup will only work with another Vista machine... That said, I found a work-around that works for me. I VPN, using TightVNC (works great) to my XP Pro and launch the Backup application and backup my Vista Documents Mark

Hi every one. Well I am at least now sorted. Solution. Changed my user name to Wd-netcenter\Guest and I used my indevidual pass word saved in the config. If I use a different log in name it reverts back to not working again. Now I can use the system back up util in Windows Vista Home Premium. Hard drive WD Netcentre Network Drive I hope this may help some one else.

Thanks Colin, I followed your advise RE: username (Wd-netcenter\Guest ) for backing up my email, since Vista backup uses shadowcopy. And it worked, I am very grateful to you sir. Regards, Robert

Could you help me out with more of a guide to doing this? I'm a system installer and great with XP, but a client wants to backup to a Buffalo Terastation NAS using Vista, and I don't know Vista very well at all. Or at least point me in a direction.Thanks so much,Bryan

Bryan - here is what I learned and what I did to make it work for me... I found out that you can only use Vista's backup with another Vista machine. I have a XP box that I use to backup my laptops here at home and it has worked great for me. I purchased a new laptop with Vista and could not backup to the box. I finally figured out that I can pull the data, instead of pushing it. So, I set up the XP box to pull my Vista data over to backup my machine. Works for me, no problems.

Ok. Here's what you need to do.1. Enable the Guess account on your target PC (XP)2. Enable password protection for the Guess account. This is done by running the command "Net user guest password" in command window (cmd.exe)3. Create a password for the Guess account. This is done in the user account panel.4. Log on as Guest.5. Create a folder that you want to backup to.6. Log off and log on as Administrator or user with administration privilege.7. Share the folder.8. Add Guest to the sharing list and give Guest complete control.Now you can backup to that folder with username Guest and the password you set up.

My system is still not allowing me to backup on the WD-Netcenter after this trick. Has anyone found another solution? It there any chance that Microsoft now has a fix that I can find?

I'm using (or trying to use) a WD MyBook World Edition drive attached to my network server. Absolutely no problem using the Windows XP backup utility.... And, absolutely no way I can get the Vista backup utility to access the drive. I'm getting the same error messages others have noted above. I've tried the password tricks noted above, without success. Either I'm not smart enough to set things up properly (the most likely cause) or it just doesn't work for this set up. Just FYI, I tried using the EMC Retrospect Express Backup Software that came with the drive. It did work, but took nearly 24 hours to backup just 70 gigs of data. That's not a viable option. I'd definitely appreciate any info anyone has on solving this glitch. I'm definitely not a techie, so novice step-by-step instructions are best.

Hello,I hope this helps. It's not great news, but at least it's an answer.I found this on the technet blogs.This is an excerpt of a chat with the Windows Vista Backup Team:"Backup Team [MSFT] (Expert):Q: Is there a possiboility that a complete PC backup can be done to a network drive?A: Backing up to a network was on our plans, but due to time limit we coudl not finish it for Vista. It will be considered for future releases."from: http://blogs.technet.com/filecab/pages/452232.aspxAccording to this, there is no way to backup Vista over a network using the current built-in backup software. So, I would consider using a 3rd party backup system like Norton 360 or something equivalent.You have to set the security settings in a specific way as well:http://technet.microsoft.com/en-us/library/bb727037.aspx#EEAA

So this is what worked for me...Set up an admin user name on the host computer (the one connected to the hard drive where your backup will be)Set up a password for the admin user on the host computerUse this as the user name/password for all your other vista computers you are going to be backing up to the host computer's hard drive.It seems vista will not allow a backup if the host computer's admin user ID doesn't have a password.Good Luck - hope this helps... it worked for me.

Ok just readyour forms. I have got a bit further than you guys but not fully solved.When set up the network drive through Vista backup and it asks your for your username and password, I figured out this works:Username: EveryonePassword: adminHope this helpsbeauty in the air

N Cohen : you are a god... it workedUsername: EveryonePassword: admini have been looking for this answer for months. thank you so much

Just try Magic Backup.It Is a service that uses our high-speed Internet connection and our Windows® PC to make backup copies of all our important files to a remote location that we provide. They install a small program on our computer that locates and makes secure copies of our pictures, movies, music, documents and other important data silently and automatically. Magic Backup keeps track of new files and changes to existing files so it always knows what needs to be backed up. It performs what they call "Automatic Continuous Backup" in the background without interfering with the normal use of our computer. Magic Backup is the only backup service we know of that will allow you to access all of your backed up files from any computer anywhere with an Internet connection and a Web browser. No need to install any software! Magic Backup

Wow, how did you figure that out? This worked for me too! thanks

Had a similar problem recently - couldn't backup from Vista to a home NAS device on any NAS share with a password associated with it. Works fine on XP or Windows 7. Everytime I entered a username and password it would fail with an error about deleting files. Answer appears to be: a) Create a user on the NAS called "Everyone" with any password. b) Use this username and password from your Vista PC. By magic it works! ------------
