Add Extension - No response

ArcGIS Server:  10.1
Description:  Logged on as ArcGIS Server admin and then tried to add (SOE) extensions in ArcGIS Server Manager in the production server's.
Problem:  After clicking the 'Add Extension' button and then loading the soe file from C:\...\, Clicked the 'Add' button.  Then I got IE warning message (see the image) [ATTACH=CONFIG]31836[/ATTACH].  The message shows the blocked site is about:blank, but actually it is http://localhost that is in the list of my IE's Trusted site zones.
Question:  What security setting should be done to eliminate the blocking?
Thanks if you can help.
