I'm trying to run the script below to check for a registry value and if it exists to run the registry imports and exports.  It runs regardless of whether the value exists in the registry or not.  This is probably only the second VBScript I've written, so I am quite new to this.  I'm using a function I found on the internet to check for the value existence, but I've got something awry.

Option Explicit
On Error Resume Next
dim objShell,objFSO, objFolder, regRDP, regTDP, RDP, TDP, strRegKey
Err.Clear
Set objShell = CreateObject("WScript.Shell")

 Function RegEntryExists(theEntry)
   On error resume next
   set shell = CreateObject("WScript.Shell")
   x = shell.RegRead(theEntry)
   WScript.Echo Err.Number
   If Err.Number <> 0 then
      RegEntryExists = 1
   else
      RegEntryExists = 0
   end if
End Function

If RegEntryExists = 1 Then
  WScript.Echo("It exists.")
else
  WScript.Echo("It doesn't exist.")
end if

If RegEntryExists("HKLM\System\CurrentControlSet\Enum\Root\LEGACY_RDPWD\0000", "Class") = 0 Then
      'Create folder C:\regbkup
      Set objFSO = CreateObject("Scripting.FileSystemObject")
      Set objFolder = objFSO.CreateFolder("C:\regbkup")
      'Make backups of the registry keys under C:\regbkup
      WScript.Echo ("Beginning Export " & Now)
      objShell.Exec "%comspec% /k reg.exe EXPORT HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\Root\LEGACY_TDTCP C:\regbkup\tdpenum.reg"
      objShell.Exec "%comspec% /k reg.exe EXPORT HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\Root\LEGACY_RDPWD C:\regbkup\rdpenum.reg"
      objShell.Exec "%comspec% /k reg.exe EXPORT HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TDTCP C:\regbkup\tdpserv.reg"
      objShell.Exec "%comspec% /k reg.exe EXPORT HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RDPWD C:\regbkup\rdpserv.reg"
      WScript.Echo ("Completed Export " & Now)

      'Import registry keys
      WScript.Echo ("Beginning Import " & Now)
      objShell.Exec "%comspec% /k reg.exe IMPORT C:\fix.reg"
      WScript.Echo ("Completed Import " & Now)
End If
