Can not log on when changed to workgroups

[Phil Campa]

I changed my network settings from DOMAIN to workgroup
and now my user id an dpassword are not recognized.
I welcome your help.

I would like to logon and changed it back to DOMAIN
settings.
Thank you

1. You must connect the PC to the network that contains the domain
controller. (take it back to work)
2. You must login as a local administrator
3. When you rejoin the domain you will have to provide a Domain
administrator account and password to join the domain.

Since most admins will not give you the information for step 2 and step 3
you will most likely have to ask a network admin to come in and rejoin it
for you.

Just a note when you remove a workstation from a domain the domain username
and password will no longer work, as you have noticed.

You will not be able to logon on
Unless you have valid "Local" logon credentials on the
machine that you are sitting at.

Your User account information(ACL,access token)
resides in the SAM on the domain controller back in the
domain you left.

Now when you attempt to logon to the "Local" computer you
are asking the "Local" SAM to authenticate your logon
request using domain credentials. You need a "Local" user
account to logon locally and Administrative credentials in
the Doamin to join a computer to the Domain.

When logging on you are presented with the option to logon
to Domain(s): or logon to computername:

When you choose to logon to the Domain you use its SAM.
When you choose to logon to computername: with the
computer already joined to a domain you are logged on
using Domain credentials that have been cached on
the "Local" computer. This is the only time that you can
use the same username and password for Domain or "Local"
logons. (the reason is that if a domain controller becomes
unavaliable users will still be able to logon to the local
machine using cached credentials.)

Essentailly When you supply a Domain Name in Network
Identification all Domain logon requests are sent to a
domain controller, as stated above you can also logon
locally using cached credential(stores the last 10
successful logons.)

When you supply a Workgroup name in Network Identification
the request looks at the "Local" SAM and never at a domain
controller.
