You can modify the retry interval by adding/adjusting the following key using the registry editor on the coordinator server:
Location: Registry
Path: HKEY_LOCAL_MACHINE\SOFTWARE\Quest\ChangeAuditor\Coordinator
Value Name: DatabaseRetryIntervalInSeconds
Value Type: DWORD (32-bits)
Value Base: Decimal
Value Data: 60 (Default)
Restart the Coordinator service to commit changes.
NOTE: Consider increasing if the coordinator is experiencing login failures due to a SQL server restart (e.g., during a patch). 3 attempts are made between each timeout interval to reconnect to the database, and this cannot be changed.
