Note: All registry entries concerned with the configuration of the WINS
server can be found under the path
HKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services\WINS\Parameters
WINS servers communicate with one another in order to achieve a complete
reproduction of their databases and to ensure that a name registered in one
WINS server will eventually be reproduced in all other WINS servers within
the combined network. All assignment changes will be collected for the
complete WINS system within the so-called reproduction period (maximum
length of time for transmission of changes to all WINS servers). All freed
names will be passed on to all WINS servers as soon as they are obsolete
according to the relevant intervals defined in the WINS-Manager.
Reproduction takes place under a reproduction partner and not between one
server and the other servers. Finally, complete copies are requested from the
other WINS servers within a combined network, but the WINS servers
transmit start signals to draw attention to the fact that a reproduction should be
initiated. For a reproduction to take place, every WINS server must act as the
Push or Pull-Partner for at least one other WINS server.
Note:All registry entries concerned with the WINS reproduction can be found
under the path
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\WINS\Partners.
Static assignments are fixed lists in which IP addresses are assigned to
computer names. These classifications may not be questioned or deleted
unless the administrator removes a particular assignment. Via the command
"Static Assignments" in the WINS-Manager, static assignments can be added,
edited, imported or deleted for clients in the network for whom the WINS
service is not activated.
Note: If DHCP is also in operation on the network, a reserved (or static) IP
address will deactivate all the settings of the WINS server. Static assignments
should not be assigned to a computer if WINS is active on the computer.
The following files are stored in the directory
%SystemRoot%\SYSTEM32\WINS. This directory is automatically created
when configuring a WINS server.
- JET.LOG is the log file for all transactions carried out in the database. If
required, WINS uses this file to recreate data.
- With the help of SYSTEM.MDB, WINS records information concerning the
structure of the database.
- WINS.MDB is the WINS database file.
- WINSTMP.MDB is a temporary file created by WINS. It can remain in the
directory \WINS following a system failure.
Note: The files JET.LOG, SYSTEM.MDB, WINS.MDB and WINSTMP.MDB
should neither be deleted nor changed in any way since this can lead to faulty
functions under WINS. Access to these files may only be granted to the
