Thanks Kent and MCA for the additional comments, loads of info. I think it was above my requirements though. Kixtart isn't installed on the clients, just in the netlogon folder (sys32\repl\..). Before reading your comments I downloaded the 4.02 version and replaced the files with the new ones. I also replaced the kxrpc service on all DCs. At first I was getting the dreaded 'Failed to locate kx16.dll' error on a client, although others were fine. I made one (I think insignificant) change to the users profile, and the error went away. At the moment it seems everything is okay. The only thing we are using kixtart for is to map drives on 9x clients and it is successfully serving that purpose. I'm hoping the 'failed to locate' error doesn't come up again. Now on to the domain upgrade. Thanks for the help everyone- please let me know if I've completely missed something. The readme file with the upgrade instructions made it seem as though it was as simple as replacing files, which is essentially all I have done.
