JSI Tip 2450. Reducing the WINS client refresh interval to a Windows NT 4.0 WINS Server.

In an environment were a DOD router is used to contact a Windows NT 4.0 WINS server, it is generally desirable to reduce the frequency of contact.

When a WINS client start it sends a name registration request to the WINS server at 1/8 the InitialRefreshTimeout, which defaults to 960,000 milliseconds (16 minutes), so the initial registration is in 2 minutes.

You can reduce the traffic by adding a static entry for the client in WINS and by setting the InitialRefreshTimeout to a larger value.

For WinNT clients, use Regedt32 to navigate to:


Edit or Add Value name InitialRefreshTimeout, as a REG_DWORD data type. Using the DWORD Editor, set the data value using the proper Radix. The minimum data value is 960,000 milliseconds (Decimal) and the maximum data value is 0xffffffff (Hex), 1/8 of which is ~50 days.

For Win9x clients, set InitialRefreshTimeout at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP.
