Heya,
If you go to install NR2003, don't do all those crazy machinations that some sites say, DEP n all. Somewhere I posted how I go about it and have no problems ever.
I could put up an ISO of my original disk in my FTP space if you want. It will just install it, won't make a CD that passes check. I have a newer NR2003.exe I came across also. The server I have up would crash every once in awhile with the W10 one that was out. It has held steady with this one.
I don't know if some create themselves a problem if they install it from the desktop, due to the security within user folders.
I may have the ISO up somewhere already.
