On Windows 7, you can use this key to enable/disable DST settings in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation Value Name: DynamicDaylightTimeDisabled Value Type: REG_DWORD

I am looking specifically for Windows 2003 DST settings in the registry. Basically I want to "enable" DST settings on a a large group of computers through the registry. Let me know if you guys know where this key is located.

You're looking for:

A key in Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation named DisableAutoDaylightTimeSet. It's a REG_DWORD type with a value of 0x1 [hex] or 1 [decimal]. If present, your computer clock will not update with DST.

If that key is absent, it means your computer will update its clock with Daylight Savings. So, you'd basically be looking to find that key (and remove it, if present) for your large number of servers.
