    Locked out of XP Home (XP Home SP1)

    My wife's XP Home machine has two user accounts - hers and mine - both set up without passwords. Thursday, the last time the system was used, I downloaded a few updates for Symantec Norton Anti-Virus and for Ad-Aware, after which I performed a check with the latter, (finding nothing significant). My wife finished what she had to do and tells me the system closed down as normal.

    Friday, when she tried to start the machine up again and log in, it presented her with a password prompt. As explained, none has been set but, what ever we do, whether there's text in the password box or not, we get the message "The System could not log you on. The server authenticating you reported an error (0xc00000BB) " and goes on to suggest I might get more information by looking at the system log (if only...!). When I set the machine up, I gave the administrator accound my default administrator password, (which I've used successfully before on this box), but this failed with the same error message.

    Googling on the error suggests it's a problem related to logging on using a smart card system, which we don't do, (and, frankly, I wouldn't know how to sety up without research). All of the suggested solutions revolve around logging on conventionally and doind some fiddling with the User accounts.

    The machine connects to the main machine in the house, (along with printers, the internet connection etc. etc.) via a Belkin wireless network card, which has functioned faultlessly in the nine months or so since it was installed. It's one machine in a basic, no-frills, peer-to-peer network and the other two machines are fine, (one XP Pro, one Windows 2000). Thinking that the PC may be trying to authenticate somehow to my machine (XP-Pro, which is almost always on), or, (worse) some Internet-based resource, I powered off the wireless router and tried a reboot. This time the error was "The system could not log you on due to the following error: Invalid access to memory location". When the router was powered up again, the first message returned. If I turn off the cable modem and leave the router on, the first message is shown.

    I'm not sure whether that tells me something or not, although it sounds like the machine is depending on something it reaches through the network, (but not the cable modem) to log in. I'm about to try booting from the XP Home installation CD and running a repair install but I thought I'd try my luck here before I take this final step.

    Has anyone heard of a similar error and (fingers crossed!) a solution?

    Thanks for reading this far.
    Regards,

    Steve

    Have you tried booting into Safe Mode to see if it will let you in that way ??

    "In Windows XP Home, the built-in 'administrator' account is only available in safe mode and is the default account for that mode. The password for the administrator account is blank, since it is not accessible except in safe mode. It's recommended that you log in as this account to make changes in safe mode."

    Thanks for your response, Doc. I tried logging into Safe Mode, both as Users and as Administrator - all failed the same way. Incidentally, Pressing Ctrl-Alt-Del at the normal XP login screen brings up a more traditional NT-style login box, at which you can (attempt to) log in as Administrator whether in Real Mode or having let the machine boot normally.

    Interesting. The Ctrl-Alt-Del trick is a standard workaround to get to a password login box. Have you attempted to use System Restore to go back before you noticed the problem ??

    Sorry for the delayed reply - I've been tied up on other things for a while. I've not tried System Restore because you have to be logged in for it to work, don't you? Or is it an option on the Recovery Console? (I've not really played with that in anger yet, so to speak)

    I must admit to terminal frustration with this one. I think I'm probably going to rebuild Windows on another HDD over the weekend and recover what data I can from the original disk after that. I've been meaning to rebuild anyway, (to incorporate SP2 if nothing else), but I get bloody-minded when Windows forces me into it by behaving in this manner .

    I'm still curious as to how the situation arose in the first place however. If I uncover anything more I'll post it back here.
    Regards,

    Steve

    Please pardon my brain-dead response. System restore is only available if you are logged on and as that is your problem (not being able to log on) you would not be able to access that utility. <img src=/S/bingo.gif border=0 alt=bingo width=15 height=22>

    You did say that this machine is part of a peer-to-peer network. Have you tried disconnecting it from the network and then booting it up ?? Since the error you are getting mentions that the "Server authenticating you reported an error", maybe removing the network connection (even if it is peer-to-peer) will get you past that error. Just a shot in the dark. <img src=/S/crossfingers.gif border=0 alt=crossfingers width=17 height=16>
