Editing remote registry

A while back we're able to edit the registry file and now it seems like we're not able to edit the reg file. We have a bunch of server's we need to change the DynamicDaylightTimeDisable from 1 oto 0.

If I'm on the remote server and run

Get-ItemProperty -Path HKLM:\system\CurrentControlSet\Control\TimeZoneInformation -Name DynamicDaylightTimeDisable

I see

PSPath                      : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\system\CurrentControlSet\Control\
                              imeZoneInformation
PSParentPath                : Microsoft.PowerShell.Core\Registry::HKEY_LOCAL_MACHINE\system\CurrentControlSet\Control
PSChildName                 : TimeZoneInformation
PSDrive                     : HKLM
PSProvider                  : Microsoft.PowerShell.Core\Registry
Bias                        : 360
DaylightBias                : -60
DaylightName                : @tzres.dll,-161
DaylightStart               : {0, 0, 3, 0...}
StandardBias                : 0
StandardName                : @tzres.dll,-162
StandardStart               : {0, 0, 11, 0...}
TimeZoneKeyName             : Central Standard Time
DynamicDaylightTimeDisabled : 1
ActiveTimeBias              : 300

So if I run

Set-ItemProperty -Path HKLM:\system\CurrentControlSet\Control\TimeZoneInformation -Name DynamicDaylightTimeDisabled -Value 0 -Type DWord

It will edit DynamicDaylightTimeDisabled from 1 to 0.

Any ideals why we're not able to edit the registry file remotely?
