IE.navigate not working on VPN

[30knotwind]

My code has been working for a full year on XP, MSIE8, Cisco AnyConnect (VPN). We recently migrated to Win7 and did not have trouble to begin with, but after a couple months it now never works on the VPN. It is giving me this error:

"The Object Invoked has disconnected from its clients" when it reaches the Do loop.

If I take out the Do loop, it gives me the same error when it gets to the next line of code, which inserts data into a form on the webpage.

The code always works without issues when I am off the VPN.

I have tried everything from lowering security settings to saving passwords, etc.

Any help appreciated!

Code:

Dim IE As Object
Set IE = CreateObject("InternetExplorer.Application")

'webpage to be edited
comment_url = ActiveWorkbook.Sheets("Comment").Range("M24").Value

IE.Navigate comment_url  'load web page

Do
DoEvents
Loop Until IE.readyState = 4

'    READYSTATE_UNINITIALIZED = 0
'    READYSTATE_LOADING = 1
'    READYSTATE_LOADED = 2
'    READYSTATE_INTERACTIVE = 3
'    READYSTATE_COMPLETE = 4

Call IE.Document.getElementById("edit-field-trader-open-0-value-datepicker-popup-0").SetAttribute("value", pos_date)

try making the IE object visible, so you can see what is going on in the browser

Trial going to your internet options setting (security) and disabling the protected mode. You also may have a registry problem that needs fixing. HTH. Dave
