SUMMARY
To use a Microsoft Windows NT 4.0 WINS database on a Windows 2000 server, you must convert the database.



MORE INFORMATION
Windows 2000 Server may convert the Windows NT 4.0 WINS database automatically. To make sure that Windows 2000 converts the WINS database, follow these steps:
 * 1) On the Windows 2000 Server, open a command prompt, type net stop wins, and then press ENTER.

Repeat this step on the Windows NT 4.0 server.
 * 1) Copy the contents of the %SystemRoot%\System32\Wins folder from the Windows NT 4.0 server to the Windows 2000 server.
 * 2) At the command prompt on both servers, type net start wins, and then press ENTER.

A message appears stating that the conversion process is taking place.

NOTE: This process can take a half hour or more to complete depending on the size of the database. Do not stop the process until it is finished. The conversion process (Jetconv.exe) normally uses a large percentage of CPU time during the conversion.

During the conversion process, you may be prompted for an additional file from the Windows 2000 Server CD-ROM. If this occurs:  Copy the Edb500.dl_ file from the I386 folder on the Windows 2000 CD-ROM to the %SystemRoot%\System32 folder on the Windows 2000 server. On the Windows 2000 server, expand the Edb500.dl_ file. To do this, open a command prompt, type the following line, and then press ENTER:

expand edb500.dl_ edb500.dll.

 At the command prompt, type net start wins to finish the conversion process.

After you restart the WINS service, you receive the following error message:

A system error has occurred.

System error 1 has occurred.

Incorrect function.

When you check the system and application event logs, you see that the database format was invalid and that Windows started the WINS database conversion process.

The conversion process may take up to an hour, depending on the server hardware and the size of the WINS database. You may notice heavy input/output activity during the conversion, and in Task Manager you may notice that the Jetconv.exe process is running.

When the conversion is completed, the WINS service resumes, and the following event appears in the application log:

Event Type: Information

Event Source: JetConv

Event Category: None

Event ID: 1000

Date: 1/17/2002

Time: 9:38:39 AM

User: N/A

Computer: LABBER1

Description:

The Jet Conversion utility has converted the database for the "WINS" service, database file in "c:\winnt\system32\wins\wins.mdb". The backup files of the old (pre-conversion) database have not been removed from "c:\winsbackup". This directory can be cleaned up to free up disk space.
