A. By default, the TCP/IP stack in NT 5.0 Beta 2 (and later builds) attempts to register it's Host (A) record with it's DNS server. This makes sense in an all NT (Windows 2000) environment. But if you are using a static, legacy DNS server, the DNS guys might not like all the 'errors' this shows up on their server since the DNS servers will not understand these "updates".
You will get errors such as:
- Failed to register network adapter with settings
- Sent update to server
To make the clients stop attempting to publish their DNS names/addresses to the DNS server perform the following:
- Log on to each client as Administrator
- Start the registry editor (regedit.exe)
- Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
- From the Edit menu select New - DWORD value
- Enter a name of DisableDynamicUpdate and press Enter
- Double click on the new value and set to 1. Click OK
If you have multiple adapters in the machine you may not want to disable for all so instead of setting HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DisableDynamicUpdate to 1, set as 0 and then move to the sub key Interfaces\<interface name> and create the DisableDynamicUpdate value there and set to 1.
If you needed to perform this on a large number of machines you should create a reg script or set from the login script.
