“Safety settings on this machine prohibit accessing a data source on another domain.” – solution

I have been building a new HTA fronted deploy ISO for multiple domains (in combination with SCCM as used on a client site) and kept coming across the error message:

“Safety settings on this machine prohibit accessing a data source on another domain.”
Stupidly, I initially assumed that this had something to do with the HTA being run from a WinPE environent – well this is partially true – but the fix applies to machines that are in workgroups / domains and even running WinPE.

It is a simple secuity tweak by Microsoft to prevent access across domains (thgouh of course when running WinPE you are not a domain member)

The fix is simple   – you simply need a regkey to define the policy setting.

the key is as follows:

head to :

 

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3

 

and create a REG_DWORD key 1406 and set it to 0

Of course if you need it for all users / default user – set it at those hives.

Simple
