Time:

Computer:

Description: The AntigenService service terminated unexpectedly. It has done this 2 time(s). The following corrective action will be taken in 0 milliseconds: No action. 



CAUSE
This problem may occur if objects in the Active Directory directory service have very long names. When the Antigen Service creates an LDAP path, the Antigen Service uses a fixed size buffer to store the path information. If you use long names in Active Directory, the size of the LDAP path that the Antigen Service creates may be larger than can be copied to the buffer successfully. Therefore, the Antigen Service exits.

This is to help reduce the probability that you experience the problem that is described in the &quot;Symptoms&quot; section when you use long names in Active Directory. Also, this hotfix adds validation checks to help make sure that a long LDAP path does cause the Antigen Service to exit. Instead, an error is logged.
