Why I don't follow 'sponsored links'
While searching for help on 'failure to decode...' error on Sharepoint 2003, google suggested this site.
The first thing of note is that it is itself a Sharepoint 2003 site.
So I entered the word 'decode' in the search box and recieved:
"Your search encountered an error. If the problem persists, contact the portal site administrator."
Bad sign. I moved on.
I don't think they're quite ready to assist me.
