NoteHKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters
| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0x0 | 0x1 - 0x418937 seconds | Ox12C (300 seconds = 5 minutes) |
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 DynamicSiteName and uses the saved site name for its operations. When the value of this entry expires, Net Logon requests the current site from the domain controller in the computer's primary domain and 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 it. Increasing this value (updating less frequently) reduces network traffic, but can result in outdated site names, especially if the site changes frequently.
Note
When an administrator enters a site name, it is stored in the value of SiteName and is used instead of the value determined automatically and stored in DynamicSiteName. 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.
