Property Value
Type: PISystemsAFDirectoryOptionsReturns the directory options used when looking up a PISystem in the collection.
Remarks
The collection methods used to look up a PISystem in the collection use the value of this property to control their behavior. When the CheckIP directory option is enabled and a host address cannot be resolved, the PISystem is added to a bad address list. The MinCheckIPTimeout and MaxCheckIPTimeout settings determine the minimum and maximum timeouts before an invalid PISystem address is checked again.
The default value for this property is read from the SDK's configuration file in the OSI directory under the CommonApplicationData directory. This default value will be the default for all clients executed on the computer. If this property is modified in the client, then it will only affect the current client and the modified value will not be persisted.
