The vCenter Server Service is unable to start if the files for the ADAM instance VMwareVCMSDS are locked, corrupt, or otherwise unavailable for accessing.

These files can be locked if they are being scanned by realtime virus scanning.


To resolve this issue, either stop scanning all.edb and.chk files or stop scanning on the ADAM instance folder, the default location is C:\Program Files\VMware\Infrastructure\VirtualCenter Server\VMwareVCMSDS.
Insufficient permissions to the C:\Program Files\VMware\Infrastructure\VirtualCenter Server\VMwareVCMSDS folder may also cause this issue. Ensure the users or group has read and write access. NT Authority/Network Service requires read and write access to this folder.

Note: In vCenter Server 5.x, the path to VMwareVCMSDS is C:\ProgramData\VMware\VMware VirtualCenter \ VMwareVCMSDS.
