strURL = alink.Address
If Left(strURL, 4) <> "http" Then
strURL = ThisWorkbook.BuiltinDocumentProperties("Hyperlink Base") & strURL
End If
Application.StatusBar = "Testing Link: " & strURL
Set objhttp = CreateObject("MSXML2.XMLHTTP")
objhttp.Open "HEAD", strURL, False
objhttp.Send
If objhttp.statustext <> "OK" Then
alink.Parent.Interior.Color = 255

Next alink
Application.StatusBar = False
On Error GoTo 0
MsgBox ("Checking Complete!" & vbCrLf & vbCrLf & "Cells With Broken or Suspect Links are Highlighted in RED.")

Edit: I changed your macro to declare variables properly and release objects upon macro completion; this should address any potential memory issues. Please try this code and let me know if it works.
Sub Audit_WorkSheet_For_Broken_Links()
If MsgBox("Is the Active Sheet a Sheet with Hyperlinks You Would Like to Check?", vbOKCancel) = vbCancel Then
Exit Sub
End If
Dim alink As Hyperlink
Dim strURL As String
Dim objhttp As Object
On Error Resume Next
For Each alink In Cells.Hyperlinks
strURL = alink.Address
If Left(strURL, 4) <> "http" Then
strURL = ThisWorkbook.BuiltinDocumentProperties("Hyperlink Base") & strURL
End If
Application.StatusBar = "Testing Link: " & strURL
Set objhttp = CreateObject("MSXML2.XMLHTTP")
objhttp.Open "HEAD", strURL, False
objhttp.Send
If objhttp.statustext <> "OK" Then
alink.Parent.Interior.Color = 255
End If
Next alink
Application.StatusBar = False
'Release objects to prevent memory issues
Set alink = Nothing
Set objhttp = Nothing
On Error GoTo 0
MsgBox ("Checking Complete!" & vbCrLf & vbCrLf & "Cells With Broken or Suspect Links are Highlighted in RED.")
End Sub
Old Answer Below
Combining your macro (which seems to be from here) with an alternative found on excelforum yields the below code. Give it a try and let me know if it works for you.
Sub TestHLinkValidity()
Dim rRng As Range
Dim fsoFSO As Object
Dim strPath As String
Dim cCell As Range
If MsgBox("Is the Active Sheet a Sheet with Hyperlinks You Would Like to Check?", vbOKCancel) = vbCancel Then
Exit Sub
End If
Set fsoFSO = CreateObject("Scripting.FileSystemObject")
Set rRng = ActiveSheet.UsedRange.Cells
For Each cCell In rRng.Cells
If cCell.Hyperlinks.Count > 0 Then
strPath = GetHlinkAddr(cCell)
If fsoFSO.FileExists(strPath) = False Then cCell.Interior.Color = 65535
End If
Next cCell
End Sub
Function GetHlinkAddr(rngHlinkCell As Range)
GetHlinkAddr = rngHlinkCell.Hyperlinks(1).Address
End Function
