Re: Computer Won't Start, Returns To Logon Screen

Thanks for this Mark.

I'm having problems with replacing winlogon.exe. I've booted in to Recovery
Console from a Win XP CD, when prompted for a windows installation to log in
to I've chosen C:\Windows, entered the Admin password and I'm in Recovery
Console. When I enter the command syntax you've given below I get "The
command is not recognised..."

Am I doing something wrong?

Another file in the process that can be replaced in winlogon.exe

run from a boot to CD and Recovery Console (press 'r' for Repair), the
command:

(cd drive letter here):/i386/expand.exe (cd drive letter
here):/i386/winlogon.ex_ %windir%/system32/winlogon.exe

The registry entry for wsaupdater should be:
expand
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
.
3. In the right pane, right-click userinit, and then click Modify.
4. Replace wsaupdater.exe (or perhaps something else) with userinit.exe

The way to access the registry from recovery console is a bit different from
the normal windows interface, using REG.EXE

How to edit the registry offline using BartPE boot CD:

Mark,

Thanks for your reply.

I successfully carried out step 1 in KB892893, i.e. Use Recovery Console
to
copy Userinit.exe to Wsaupdater.exe, but the machine still cannot get past
the logon screen.

I think that the problem is probably that described in KB892893 as the
user
ran Ad-Aware immediately prior to the problem occurring.

I guess System Restore might be an option but the user isn't sure when he
became infected and the last time he scanned the computer was around March
this year.

Any advice you can give would be greatly appreciated,
Malcolm

I'm an IT Technician and I support small businesses and home users.

I've got a call from a business user regarding a PC with Win XP Pro
plus
latest updates. He has done some maintenance work on the computer
defragging,
spyware scan and removal, etc and now the PC won't start beyond the
user
style (as opposed to CTRL-ALT-DEL) logon screen.

When the computer starts it stops at the logon screen displaying an
icon
for
his user account. When he clicks this icon the computer tries to get to
the
desktop but comes right back to the logon screen with no error message
displayed. He reports that the machine did not display the logon
screen,
i.e. went straight through to the desktop, until this problem occurred.

The user doesn't think the machine will boot in to safe mode but he's
not
sure.

The user will not be back in the office for 48hrs which is when I have
an
appointment to examine the machine. If I can boot in to safe mode I
will
try
running system restore from the command prompt but wondered if anyone
else
had any other ideas for resolving this?
