You may want to configure Windows NT unattended Setup so that LMHOSTS lookup is disabled. This article describes how to disable LMHOSTS lookup during a Windows NT 4.0 unattended Setup. MORE INFORMATION ================ To disable LMHOSTS lookup during unattended Setup, follow these steps: 1. Create a new share on a network server and then copy the I386 folder (or appropriate platform folder) from the Windows NT 4.0 CD-ROM to the new share. 2. Using any text editor (such as Notepad), add the following entry to the [Unattended] section of the Unattend.txt file: OEMPreinstall = Yes 3. Save and then close the Unattend.txt file. 4. Create a new folder named $OEM$ in the share you created in step 1. 5. In the $OEM$ folder, create a file with the following entries. Save the file as .reg, where is your choice of names (for example, Mychange.reg): REGEDIT4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters] "EnableLMHOSTS"=dword:00000000 6. In the $OEM$ folder, create a file named Cmdlines.txt. This file should contain the following entries, including the quotation marks surrounding the entry [Commands] "Regedit.exe /s .\.reg" where is the name of the registry file you created in the previous step. 7. Copy the Regedit.exe file from the share you created in step 1 to the $OEM$ folder. 8. Run Windows NT 4.0 Setup in Unattended mode using the Unattend.txt file. For example, use the following command "winnt /u:unattend.txt /s:" (without the quotation marks) where is the location of the shared folder you created in step 1.
