SiteNameTimeout

HKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters

Data type

Range

Default value

REG_DWORD

0x0 | 0x1–0x418937 ( seconds )

Ox12C ( 300 seconds = 5 minutes )

Description

Determines how often Net Logon automatically updates its record of the site in which the computer is located. Net Logon saves the name of the site in the value of the DynamicSiteName entry, and it uses the saved site name for its operations. When the value of SiteNameTimeout expires, Net Logon requests the current site from the domain controller in the computer's primary domain, and it updates DynamicSiteName.

Value

Meaning

0x0

The site name is updated each time it is returned to the caller.

0x1–0x418937 (49 days)

Specifies the time between updates.

The default value is optimal for most installations, but you can add this entry to the registry to change the value. Increasing the value has the effect of updating the site name less frequently and reducing network traffic, but it can result in outdated site names, especially if the site changes frequently.

Note Image Note

When an administrator enters a site name, it is stored in the value of the SiteName entry, and this value is used instead of the value determined automatically and stored in the DynamicSiteName entry. When SiteName is populated, the site name is not updated automatically, and SiteNameTimeout is not used.

This entry is used only on client computers and member servers. Net Logon does not update the site name of domain controllers.

Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
