Can't logon to windows

[Guest]

I changed some network settings from a domain network for at the office to a
workgroup for a travel network between two laptops using a wirless router.
After i did this the laptops then required windows logon. I don't know the
username and password to get into windows to change it back so i can actually
use the laptop. Any help would be great!!!

You could try Administrator and no password, but I doubt
that will work. Certainly you had a user name and
password when it was on the domain? Wouldn't it be the
same?

I just created the same problem last night. Tried to make changes to old
corporate network domain to use at home as well on wireless network and upon
restart my old username and password do not work. Anyway of bypassing this
and setting system restore to point before I made the cnhanges?
