SYMPTOMS
When you perform an automated export of the Exchange Server directory, the following event ID message may be logged in the Application event log:

Event ID: 179

Source: MSExchangeDSExp

Description: Unable to initialize directory user agent (DUA) workspace.



CAUSE
This issue can occur because there is a resource limitation in Dapi.dll; the maximum number of directory operation sessions is 10.



WORKAROUND
To work around this issue, schedule exports to be run sequentially rather than simultaneously.
