When trying to open .txt or pdf's from all client machines (XP sp2 and sp3, Vista Sp1) you get the following error. "The filename, directory name, or volume label syntax is incorrect' . You can after you get the error use the file menu of the assosiated app (notepad or Acrobat respectively) to do a File->Open->Browse to the file and open it normally.Oddly though you can open any MSOffice file (Word, Excel, PP, Access) with no errors at all. An additional issue is that you cannot double click on any file or directory object ot open them you have to Right Click and select either Explore or Open to open anything. I have spoken with microsoft and they gave me 2 Hotfixs to try but they did not work. I will list the KB's in the code box below. This one is a tough one, any insight would be appreciated.
