Microsoft Hotfix KB2577795

If you have enabled WebUI on an BigFix server running Windows Server 2008 R2, you must patch that computer with Microsoft Hotfix KB2577795.

Windows Server 2008 R2 contains a bug related to kernel socket leaks. If your primary server is on this operating system, the bug must be patched to avoid long-term issues related to WebUI. This hotfix must be applied to Windows Server 2008 R2 or the WebUI cannot be enabled. The only way to apply this Microsoft Hotfix is through direct download from Microsoft. To read more about the hotfix and download it, see https://support.microsoft.com/en-us/kb/2577795.

If KB2577795 is not applied you might see socket errors after some time has passed.

After the WebUI has been enabled, you can quickly check your server's compliance:

  1. From the BigFix console, navigate to BigFix Management > BES Component Management > WebUI, or locate Fixlet 2251 by your preferred means.
  2. If Fixlet 2251 is relevant, you have a computer that matches all of these criteria:
    • WebUI is enabled,
    • The operating system is Windows Server 2008 R2, and
    • KB2577795 is NOT applied.
  3. If Fixlet 2251 is relevant, the issue is not resolved. If Fixlet 2251 is not relevant, your WebUI deployment is properly patched.
Note: Because the WebUI enablement Fixlet requires the hotfix to be applied to relevant servers, it is unlikely that the hotfix Fixlet will be relevant. This can occur, however, if the WebUI was manually enabled, which is not recommended.
