Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Microsoft Windows 2000 running the Terminal Server 90-day trial version, and possibly other versions, does not apply group policies to incoming users when the number of connections to the SYSVOL share exceeds the maximum, e.g. with a maximum number of licenses, which can allow remote authenticated users to bypass group policies.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

In Windows 2000 Terminal Server (90-day trial and possibly other versions), when the number of connections to the SYSVOL share exceeds the maximum (e.g., due to license limits), group policies are not applied to incoming users. This allows remote authenticated users to bypass security group policies.

MitigationSince this affects deprecated Windows 2000, the primary remediation is migrating to a supported Windows Server version. Ensure proper Terminal Server licensing is in place and apply any relevant Microsoft patches for group policy handling.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the operating system version
    Run 'winver' from command prompt or check System Properties - the OS must be Windows 2000 for this CVE to apply
    Affected if The system is running Windows 2000 Server or Windows 2000 Professional with Terminal Services enabled
  2. Confirm Terminal Services is installed
    Check Services list for 'Terminal Services' service or run 'query termserver' from command line
    Affected if Terminal Services is installed and running on Windows 2000
  3. Verify Terminal Services licensing mode
    Check Terminal Services Configuration - Licensing tab or registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\TerminalServer\LicenseServer
    Affected if Licensing is set to 'Per Seat' or license server is unavailable/unreachable, causing connection limits to be enforced
  4. Check SYSVOL share accessibility
    Run 'net view \\servername' or 'net share' to verify SYSVOL share exists and is accessible from the terminal server
    Affected if SYSVOL share is not accessible or connections to it would be rejected due to license/connection limits
  5. Verify group policy application
    Run 'gpresult /r' from a terminal services session or check Event Viewer Application log for Group Policy errors
    Affected if Group policies are not being applied to incoming terminal services users, or Event ID 1000 or 1030 errors related to Group Policy appear

A user is affected if they are running Windows 2000 with Terminal Services enabled and the SYSVOL connection limit is being reached or licensing constraints prevent proper group policy application to new sessions.
