Lotus Notes uses a cache to store last known server address. It is useful to speed up the connection but if the server ip address changes it will still search the old one.

This technque is called "Notes Name Service Cache (NNSC)" and it is used from the server domino and from client notes.

The cache are stored in fields that starting with $savedxxxx.

The server uses the "Server Document" stored in the NAB Name Address Book (Domino Directory).

The client uses the "Location Document" stored in the Client Address Book.

SERVER  FIELDS

$SavedAddresses 
$SavedPorts 
$SavedServers 
$SavedDate 
$SavedTriedDate

CLIENT FIELDS

$SavedAddresses 
$SavedPorts 
$SavedServers 
$SavedDate 
$SavedTriedDate

HOW TO CLEAR THE CACHE

Just deleting the fields as show in the following simple lotus formula agent.

FIELD $SavedAddresses:=@DeleteField; 
FIELD $SavedDate:=@DeleteField; 
FIELD $SavedPorts:=@DeleteField; 
FIELD $SavedTriedDate:=@DeleteField; 
FIELD $SavedServers:=@DeleteField; 
SELECT @All

HOW TO DISABLE THE CACHED ADDRESSES 

If you use a dns failover like DNS Made Easy, the lotus Notes Cache could or better is a problem. Luckily there is a way to disable it.

Add in you notes.ini the following entry

DONT_USE_REMEMBERED_ADDRESSES=1
