    Unable to login to the network

    We've got 2 Win98SE machines left on the production line and both have problems authenticating to the network. The one I'm working on now is a real head-scratcher. (I haven't worked on WIn98's in many many years.)

    The operators problem is they can't log into the network so they have to 'sneaker-net' their data via floppy disk to an adjacent PC.

    What I've found is that while we can't login to the network, when I cancel out of the login dialog, the PC loads the OS. I can confirm that the NIC is OK and properly set up (I think). I see the Network Adapter listed twice, once by itelf and again with TCP/IP=> infront of it. I think that means it's bound to that protocol.
    I do an IPCONFIG /ALL and see that the "1st" ethernet adapter (labeled "0") has no IP (0.0.0.0) while the nect (labeled "1") has an IP. The IP is valid and I see the Gateway, WINS server, DHCP server. So it's getting an IP; the lease date-time begin and end confirm that. So, why won't it log in to the network? What am I missing?

    A supervisor mentioned that "some big upgrade" last December (long before I got here) caused problems. The other machines were swapped out for Win7 and these are the last two - due to be swapped out in 2013. Could it be that it's on the server end? That some needed component to communicate with Win98SE is misssing?

    Sure it could have become incompatible with some update, especially if the problem is the same in both systems. You might have to check with the systems on their own simple homogenous network to confirm before investing more time. Problem is that 98SE hasn't been supported in ages so there's no obligation on anyone's part to assure they are compatible with any sort of update/upgrade.
    I even have network problems going from XP to Win7 server stations when certain security protocols/programs are in place.

    Thanks guys. I think the thread link will help. I also found some MS articles that might help me:
    Article # 192534, Troubleshooting Windows 95/98/98 Second Edition Network Connection Problems
    Article # 239869 How to enable NTLM2 authentication
    Article # 288358 How to install the Active Directory Client Extension

    The 2nd one might be the big help. I thought the last would, but the link is broken to download the Extension. I'll try this out tomorrow and report back on the results.

    Sorry it took so long to reply; lots of "fires" to work on lately.
    I had a chance to try the Troubleshooting steps (see above post) and it occured to me to try various connectivity tests from the MS-DOS prompt.
    NBTStat showed the PC in Listening mode.
    I was able to PING my laptop, and TraceRoute made the trip in 1 hop.
    ARP-a displayed the IP of the adapter (which is a valid IP) and the IP of the Default Gateway (again, valid).

    So I suspect that the DC isn't set for compatibility with the authentication scheme in the Win98SE boxes. Using MS Article # 239869 How to enable NTLM2 authentication, I know that NTLM 2 is what I need, so I'll check later today whether it has been enabled on the PC's. I hope so as the download link for Active Directory Client Extensions is no longer working on MS's site. I'll then coordinate with the network side on the authentication level they've enabled.

    Any other ideas I should consider?

    A bit more progress today. I verified that each of the 2 Win98SE PC’s have the Active Directory Client Extension installed, so that means it can do NTLM 2 authentication. However, I think the encryption version of one of the files (Secur32.dll) is inadequate – one PC has the default 56-bit encryption and the other is (probably) less than that. [To tell this, you look at the Version tab under Properties for this DLL. If it says “Microsoft Win32 Security Services (Export Version)” its 56-bit; if it says “Microsoft Win32 Security Services (US and Canada Only)” its 128-bit. The other had something else in parentheses so I can only speculate what key length it has.

    If the server requires 128-bit as a minimum, then this is our problem. I think we should also look to see if the DC (I assume it’s running WinSer2008 R2) supports NTLM 2 authentication.

    I'll get the network guys to take a look.

    I tried to check the Local Security Policy, but can't find it. I want to check the setting for "Network Security: Minimum session security for NTLM SSP based client" and see if it's set for NTLM 2. It could be the problem; I want to run down all possibilities. Anyway, where can I find it?

    EDIT: Should have done a better job in researching this; Win98SE doesn't have this.
