Logon Script not working .. specific failure circumstances

I paired the script down to just creating a test folder ... the %date% has syntactically incorrect punctuation that causes an error on a pure test environment (my own workstation) ... but still not creating the test folder ...

There was another instruction (call it TASK#2), separate from the VB script that was and is running just fine ... ripped out TASK#2 and placed it in a separate GPO ... still works just fine ...

Again, the VB script is just not "stuffing" the SQL database with the logon event ... but it's fine with "stuffing" the logoff event ... here's a copy of the script to help visualize what we're attempting:

=============================================================================
' -- ADODB Locktypes --
Const adLockReadOnly                              = 1               ' Default. Read-only records
Const adLockPessimistic                              = 2            ' Pessimistic locking, record by record. The provider lock records immediately after editing
Const adLockOptimistic                              = 3            ' Optimistic locking, record by record. The provider lock records only when calling update
Const adLockBatchOptimistic                        = 4            ' Optimistic batch updates. Required for batch update mode

' Attach to the database
Set objDBConn = CreateObject("ADODB.Connection")
objDBConn.open "Provider=SQLOLEDB.1;Integrated Security = SSPI;Trusted_Connection=Yes;Security=Persist Security Info=True;Initial Catalog='Audit';Data Source='sqlutil';"

Set objNetwork = CreateObject("WScript.Network")
Set objRS = CreateObject("ADODB.Recordset")

If WScript.Arguments.Count = 1 Then
      objRS.Open "EventLog", objDBConn, adOpenKeyset, adLockOptimistic
      objRS.AddNew
      objRS("EventHost") = UCase(objNetwork.ComputerName)
      objRS("EventUser") = LCase(objNetwork.UserName)
      objRS("EventType") = LCase(WScript.Arguments(0))
      objRS.Update
      objRS.Close
End If

They are Remote Desktop Servers running 2008 R2 ...

Logged on to RDS with Domain Admin rights.  Ran RSOP.MSC and the Logon script is present ... along with your test ... the VB script ran and logged my Logon (event 4624) both in the Security Log of the Event Viewer and stuffed the info in the SQL database ... as expected ... but your test folder did not get created ... logging off also was logged in the Security Log and stuffed into the SQL database.

Logged on as standard domain user and nothing happened.  Logged off and the event appeared in the Security Log and the VB script was able to stuff the event into the SQL database ...

Nothing seems to be able to change these actions ... beginning to redefine "insanity" ... only with different circumstances yielding the same result!!!
