Hi, When i click on "Search PI Data" button to look for a PI Server and add a tag, it fails and shows just like a aspx page failure asking me to change the secuirty mode etc. It fails with any web part i try to add. I can not add a tag. It used to work before and i can see older pages perfectly ok. The PI server has trust and is good.
PI Web Part 2010, Share Point 2010 and Windows 2008
