mike888,
I'm sorry you're experiencing issues. If you're still experiencing issues
accessing a shared folder from Vista to W98, 95, ME), then it may be a
mismatch with the version of NTLM. By default, Windows Vista uses NTLM 2.
As the article
http://www.microsoft.com/technet/network/evaluate/vista_fp.mspx recommends,
To resolve this issue, you can do one of the following:
• Enable NTLM 2 support on the computer or device to which the Windows
Vista-based computer is attempting to connect. For computers running versions
of Windows prior to Windows XP, see How to enable NTLM 2 authentication. For
computers running operating systems other than Windows, see the operating
system's product documentation for information about how to enable NTLM 2
support. For network devices, see the device's product documentation or Web
site for information about how to enable NTLM 2 support or download a
firmware update that supports NTLM 2. This is the preferred solution.
• If you cannot update the computers running operating systems other than
Windows or your network devices to support NTLM 2, change the
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\LMCompatibilityLevel
registry value on the computer running Windows Vista to 1. This solution is
not recommended.
