I am kinda familiar with how touchy of a situation this is.
Back in the day during the Y2k craze, we did some work for an engine shop that was a supplier for NASCAR. One of them being the station that controlled the huge CNC machine that cranked out the heads from a block of aluminum. There was a lot of teeth clenching and breath holding that day!

The problem is that I assume whenever the file server gets upgraded to Server 2008 R2, the same problem will occur. Ken Cornetet 812.482.8499 To err is human - to moo, bovine.

Currently, the domain is running on Server 2003 DCs, but I am in the process of upgrading to Server 2008 R2 DCs. I have already started to deploy Server 2008 DCs. I have one location that has a couple of Windows 95 computers, and they cannot authenticate against a Server 2008 R2 DC - even with what I think is the appropriate group policy (the same policy allows the Windows 95 machines to authenticate against Server 2003 DCs). OK, I know, Windows 95. But, these are used as controllers in some multi-million dollar machinery that was purchased long ago from a company that is now defunct. Replacing this equipment is simply not an option. Upgrading the OS is not an option. Installing the AD client extension for Windows 9x *might* be an option, but only as a last resort. The factory guys who maintain this equipment obviously do not like to stir the soup, because the apparently only human left on earth who can support this equipment charges 5 figures to just answer the phone. Here's what I have in the Default Domain Controller Policy: Microsoft network client: Digitally sign communications (always) Disabled Microsoft network server: Digitally sign communications (always) Disabled Microsoft network server: Digitally sign communications (if client agrees) Enabled Network security: Do not store LAN Manager hash value on next password change Disabled Network security: LAN Manager authentication level Send LM & NTLM - use NTLMv2 session security if negotiated Allow cryptography algorithms compatible with Windows NT 4.0 Enabled Any suggestions?
