There are known issues with SMB signing between Windows 2000 and XP Pro in certain
cases that can cause irregular network connectivity. Assuming that none of your
network computers are configured to require SMB signing with the "always" security
option configured in their effective settings in Local Security Policy you can
configure your Windows 2000 server to not use SMB signing. In Local Security Policy
of the server [or Domain Controller Security Policy for domain controllers] go to
security settings/local policies/security options and disable [not to undefined] the
four security options for "digitally sign communications". Then run secedit
/refreshpolicy machine_policy /enforce on the Windows 2000 server. the link below
explains this some more. --- Steve
