GetCurrentUserName() is causing crash in MS Access 2010 - ms-access-2010

Question

I am running Windows 7 Professional. I have an MS Access frontend to an MS Access backend. The form that opens at the start of opening the frontend causes the app to crash.
Here is the code:
Private Sub Form_Open(Cancel As Integer)
Dim strMyDir As String
Dim intPos As Integer
Dim rst As dao.Recordset
Dim strSQL As String
Dim rstWhatsNew As dao.Recordset
DoCmd.ShowToolbar "Database", acToolbarNo
DoCmd.ShowToolbar "Toolbox", acToolbarNo
DoCmd.ShowToolbar "Form View", acToolbarNo
If Application.GetOption("ShowWindowsInTaskbar") = -1 Then
Application.SetOption "ShowWindowsInTaskbar", 0
End If
If DLookup("Locked", "luLockOut") <> 0 Then
MsgBox "Database is being worked on. Please try back in a couple minutes.", vbInformation, " "
DoCmd.Quit
Else
strSQL = "Select * From tblLastLogins Where UserName = '" & GetCurrentUserName() & "'"
This is where I have traced the error to: GetCurrentUserName()
Set rst = CurrentDb.OpenRecordset(strSQL)
With rst
If Not .EOF Then
.Edit
strSQL = "Select WhatsNewID From tblWhatsNew Where DateAdded >= #" & !LastLoginDate & "#"
Set rstWhatsNew = CurrentDb.OpenRecordset(strSQL)
While Not rstWhatsNew.EOF
DoCmd.OpenForm "frmWhatsNew", , , , , acDialog, rstWhatsNew!WhatsNewID
rstWhatsNew.MoveNext
Wend
rstWhatsNew.Close
Set rstWhatsNew = Nothing
Else
.AddNew
!UserName = GetCurrentUserName()
End If
!LastLoginDate = Now()
!IsLoggedIn = -1
Me.txtLastLoginID = !LastLoginID
.Update
.Close
End With
Set rst = Nothing
DoCmd.OpenForm "frmPrivacyNote"
Debug.Print Me.txtLastLoginID
End If
I need to track the username, so if GetCurrentUserName() is outdated, what is the current syntax?
Further follow up. I could not find data on Bing for GetCurrentUserName(), for good reason. It is a function within a MOD, so I need to figure out why the MOD is not getting called, or is malfunctioning.
After further delving, I found a Referenced MDB that has another function created by one of our users that is the cause of this error.
This is currently not an issue of MS Access working incorrectly. It is an issue with user created code.

Answer 1

GetCurrentUserName() is not defined by Access, so you should have looked at (and posted) its code.
If you are looking for the Windows user name, use this function:
Public Function GetUserName() As String
' GetUserName = Environ("USERNAME")
' Environ("USERNAME") is easily spoofed, see comment by HansUp
GetUserName = CreateObject("WScript.Network").UserName
End Function

Answer 2

The link below would suggest that
CurrentUser()
is the function
CurrentUser()

Andre, thank you very much for the insight! I found this link:

Dim objNet
On Error Resume Next
'In case we fail to create object then display our custom error
Set objNet = CreateObject("WScript.NetWork")
If Err.Number <> 0 Then 'If error occured then display notice
MsgBox "Don't be Shy." & vbCRLF &_
"Do not press ""No"" If your browser warns you."
Document.Location = "UserInfo.html"
'Place the Name of the document.
'It will display again
End If
Dim strInfo
strInfo = "User Name is " & objNet.UserName & vbCrLf & _
"Computer Name is " & objNet.ComputerName & vbCrLf & _
"Domain Name is " & objNet.UserDomain
MsgBox strInfo
Set objNet = Nothing 'Destroy the Object to free the Memory
