LAN "logon" failure

[Rizzzo]

I have two computers that are networked through a router.
Until recently I was able to share files between both
computers. But for some reason now I can only access and
share files between Computer 1 and Computer 2, but not
between Computer 2 and Computer 1.

When attempting to access Computer 1 files from Computer
2, the following error message appears on Computer 2:

"\\Computer 1 is not accessible.

Logon failure: the user has not been granted the requested
logon type at this computer."

I've searched through the Microsoft knowledge base and
have only found information about this error message
pertaining to Windows 2000 Server, 2000 Workstation, and
NT, but not for plain ol' Windows 2000 Professional. Even
if the information in the above referenced articles were
to apply to Windows 2000, the information is way too
technical for me to understand, so I would need some help
following the resolution instructions for this error
message. Of course, we'd have to determine which
resolution instruction applies to my problem.

I do not recall making any changes to the existing network
configuration when this started happening, unless
downloading a Windows 2000 updaten modified the network
configuration automatically.

I've read all I can find about networking and file sharing
through LANs and have tried everything I can think of to
allow Computer 2 access to Computer 1 files, but still get
the same error message.

Some background information: Both computers run on Windows
2000 Professional, both have been upgraded to SP3 with all
critical updates (I'll download SP4 once I've resolved
this problem as I usually backup one computer to the
other, which I cannot do right now), all drives are FAT 32
formatted, no virus scan (Norton AV Professional) shows
any viruses on either system.

Any help, suggestions, or reference to web pages is
appreciated

Make sure that on Computer 1 you have a user account that is identical to
the user account used to logon to Computer 2 (same name and password).
Give that account appropriate access rights to the folders you are trying
to share on Computer 1.

Hello rizzzzo,
logon two computer with same user name and password. If
two systems are windows xp check network settings. On
properties tab you find authentication tab, remove the
check mark and try. If you have win98 or win95 check file
and print sharing for microsoft networks options nad try.
