Migrate On/Off Does Not Allow Overwriting Static <1Ch> Mappings

ID: Q171794

The information in this article applies to:

Microsoft Windows NT Server versions 3.51, 4.0

SYMPTOMS

The static <1Ch> entries in your Windows Internet Name Service (WINS) servers are not being overwritten by dynamic entries, even though you have Migrate on/off enabled.

RESOLUTION

To resolve this problem, you will need to manually delete the static mappings using one of the following methods:

To delete the static mapping entries, use WINS Manager and perform the following steps:

From the Mappings menu, click Static Mappings.

Select the desired mapping, and then click Delete Mapping.

Click Yes to confirm the deletion.

Use the Winscl utility, available from the "Windows NT Resource Kit." Refer to the online help for Winscl, by typing winscl.exe /? at a command prompt.

After you have removed the static entries, the domain controllers for that domain will need to be restarted or the entries will not be refreshed until half of the domain controllers' renewal interval with WINS.

NOTE: This is especially important in the case of <1Ch> entries, because these are queried by clients requesting domain controllers for domain logon validation. If clients are unable to get a list of domain controllers from WINS they may get a Domain Controller not found error message and in many cases lose access to domain resources.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0 We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
