Using Windows Registry – Creating a .reg file
a. Create a text file.
b. Copy the following entries (in bold) and paste in the text file (it is very important to keep these entries as it is with the blank spaces and line breaks):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
“lmcompatibilitylevel”=dword:00000000
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]
“ntlmminclientsec”=dword:00000000
“ntlmminserversec”=dword:00000000
c. Save the file as ntlm.reg.
d. Double click on ntlm.reg and click “Yes” in the dialog box that appears next asking you whether you want to save the changes in the registry.
Note: Please ensure that the first line of your .reg file reads “Windows Registry Editor Version 5.00” for Windows 2000, Windows XP and Windows Server 2003 based machines or “REGEDIT4” for Windows 98 and Windows NT 4.0 based computers.
