Having inconsistencies when Win9x users run login scripts. Some Win9x clients work, others do not work. Problem with both Win95 and Win98 clients.

Exhausted searches on the board for past several days. I am now at a stand-still.

Performed the following troubleshooting steps:
1) Just to be sure...uninstalled KRPC service (v. 4.02) on ALL winnt DCs.
2) Re-downloaded Kixtart v. 4.02
3) Reinstalled the KRPC service, using newly downloaded files on ALL winnt DCs.
4) Rebooted DCs.
5) Rebooted problem PCs.

Still experiencing inconsistencies with Win9x clients running login scripts.

Thanks in advance for any and all help with this matter.
