Management servers or assigned agents unexpectedly appear as unavailable in the Operations Manager console in Windows Server 2003 or Windows Server 2008

Consider the following scenario:

• You install a Microsoft System Center Operations Manager root management server or a Microsoft System Center Operations Manager management server on a computer that is running Windows Server 2003 or Windows Server 2008.
• You open the System Center Operations Manager console to view management servers and assigned agents.

In this scenario, either management servers or the assigned agents may be displayed as unavailable even though the health state of the management servers is displayed as healthy.

This issue occurs because the database that is used by the health state is corrupted. This database corruption is caused by an issue in the storage engine of the jet database that is hosted on Windows.

Windows Server 2008 file information notes

Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

• The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

  Version	Product	SR_Level	Service branch
  6.0.600 1 . 22xxx	Windows Server 2008	SP1	LDR
  6.0.600 2 . 22xxx	Windows Server 2008	SP2	LDR

• Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.
• The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. MUM files and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
