SYMPTOMS
When you log on to the Compass client, you may receive the following error message:

Unable to bind

If you try to stop and start the Zoomit Server service, the following error message occurs:

Dr. Watson : **Essential OID definition missing, failed to lookup user password**.



CAUSE
There is a 2-gigabyte (GB) size limit on the X500.db database file in Metadirectory Services. When this size limit is reached, the error messages listed above occur and the directory is inaccessible.



RESOLUTION
To resolve this issue:
 * 1) Restore from the most recent working backup.
 * 2) Immediately run the Via Compact utility.

Using the Via Compact utility regularly can keep your database compact, reducing the chance that the database will reach the size limit. For more information about the Via Compact utility, please see the following article in the Microsoft Knowledge Base:
