windows 2000 - log on screen problem

[Guest]

I have a PC with windows 2000 professional loaded at factory. Went to turn
on and there's a "Log on to Windows" screen. No idea what user name or
password was--- don't even recall setting them.

Anyone know how to get around this security screen?

Thanks

Have you tried administrator with no password? That would be the default if
it was never set.

tried that... did not work. So the log-on must have been set. A username I
can recognize does appear in the "user name" field, but no password I've
tried has worked.

what else can I try?

Hi,
Don't know if you can help but I'll try....
Have desktop that was working fine and now that we've returned from holidays
it won't boot up. Goes to Microsoft Windows 98 Start-up menu. Can't operate
in any of the 6 options it gives me including "Safe Mode". Is telling me
that windows HIMEM.sys, windows DBLBUFF.sys and Windows IFSHLP.sys are
missing or corrupt. Takes me to a "C" prompt and tells me to type the name
of the Command Interpreter with an example but I'm not sure what the Command
Interpreter is. Can someone please help me? I cannot utilize any printers,
or other networked devices until I get this desktop up and running.
Much appreciated
