Windows

The first box that pops up is the Welcome To Windows box. It says requiring this key combination at startup..........

First, it must be a local user account, try a blank password if it just set it up, or try an administrator password.

You do realize though, that now it will need to be re-added to the work domain! Right? The printer could have been accessed along with other home network resources without removing it from the domain. You might have some tech's at work get upset. Anyway, try a system restore and see if you can restore it back to the domain config.

Toms Networking web site has almost the exact same question posted there. Check out their answer at http://www.tomsnetworking.com

To avoid joining to a workgroup and then again to domain, you can use a batch file to logon to the home network.
-----
@echo off
NET USE H: /delete /y

echo *** Enter the domain:
SET /p domain=

echo *** Enter the username:
@echo off
SET /P user=
echo *

echo *** Enter the password:
@echo off
SET /P something=

REM ***ShareResources (drive, folder)
NET USE H: \\HomeComputerName\HomeShare/U:%domain%\%user% %something%
if errorlevel 1 goto wrong

REM *** SharePrinter
NET USE \\HomeComputerName\SharePrinterName /U:%domain%\%user% %something%

goto end

:wrong
echo *
echo *
echo ****************************************************
echo ****Check the UserName, Domain/Workgroup & Password !
echo ****************************************************

:end
echo *
echo *
pause
exit

The "domain", "user" and "password" are HomeWorkgroup, an existing HomeUser account and his password.
If you don?t want to enter every time the "domain", "user" and "password" you can put them all in this batch and remove the lines with the "SET /P ?"
The home network must be set to use the same IP class with the domain network.
The notebook user must have a local profile, he can use the domain account to "log on" on to notebook and then he must run this batch to access resources from home network.

None of the answers thus far help me get into the notebook. That is the first issue.

I used an offline password and registry editor to blank the password for the guest account. On reboot I tried to log on and received this error. The local policy does not permit you to log on interactively. The network admin from his company has set up several local accounts. If I blank the admin account will it give me access to the notebook. I know you admin guys are going to be upset, however this is what my client asked me to do.

I was able to blank out the admin password and it logged on locally. System properties under computer name shows as the computer name and the workgroup is listed. Now when I click on the change button and try to join the domain I get this error. A domain controller for the domain could not be contacted.
Ensure that the doamin is typed correctly. I have entered the correct doamin name.
