I hope this is the correct forum for this question. I have an exe which basically migrates client computer to the new print server. I am using GPO user logon (run at logon) to perform this. It all works fine when the exe resides on a non DFS dir. once I try to run it from DFS i get a msgbox saying its an unsigned app. So being that the exe is from our .com dfs I am assuming that the protocol being used is http.(i think) and this is perhaps warning me of the unsigned software. Is there something I can do to bypass this security measure to run this exe.. I hope thats enought info.. if not I will amend Ron - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
