What key in windows registry disables IE connection parameter "Automatically Detect Settings" ?

Question

I'm trying to set all the connection settings in IE.

I've found how to modify most of them, in the path :

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings

But I can't find the parameter that sets or unsets "Automatically Detect Settings".

Any help ?

Answer 1

I found the solution : it's the 9th bit of this key :

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections] "DefaultConnectionSettings"=hex:3c,00,00,00,1f,00,00,00,05,00,00,00,00,00,00, 00,00,00,00,00,00,00,00,00,01,00,00,00,1f,00,00,00,68,74,74,70,3a,2f,2f,31, 34,34,2e,31,33,31,2e,32,32,32,2e,31,36,37,2f,77,70,61,64,2e,64,61,74,90,0e, 1e,66,d3,88,c5,01,01,00,00,00,8d,a8,4e,9e,00,00,00,00,00,00,00,00

Seems the different possible values are:

01 - neither of those 2 auto config boxes are checked

05 - just the Use automatic configuration script is checked

09 - just the Automatically detect settings is checked

0d - both of them are checked

You can always just export the registry, change the setting, then export the registry again and do a diff.

I can confirm this works. I exported the reg file after I had made the adjustments and then put it in a logon script like this:

REM ------ IE Auto Detect Settings FIX ------------------------------ REG IMPORT \mydomain.local\netlogon\IE-Autofix.reg 2>NUL
