Account Lockouts coming from WIN 98 machines

[Roy M]

About once or twice a day, I'm showing in my netlogon.log
file, login attempts from certain WIN98 machines on my
network that's locking out the account that those
machines use. These are hundreds attempts a second. I
tried giving them another account to use, but the
situation follows with that account as well. It's in a
learning lab and it's not always from the same machines.
Sounds like the Randex virus right? Well when I scan the
machines (latest virus defs.) nothing shows up. I've got
Directory Service client loaded on these machines
thinking that would stop it, but no success.

This seems to have happened ever since we moved from a
NT4.0 to a 2000 domain on this LAN. Again, it's coming
from only the 98 machines.

Thanks for any help

Got WINS installed on the server? W9x still needs it. Also options 044 and
046 (0x8) in DHCP server, Scope options. Does the winipcfg show that
everything is pointing to the server-IP?

Yes, everything checks out in those areas.

There are known isses with W98 in a W2K domain in some cases. I believe
there is a updated version of the Directory Services Client available from
MS. See the KB link below for more info. You also want to be using wins if
you are still using W98 computers, though I doubt that has anything to do
with the problem. Also see the second KB link about how various security
options and user rights assignments can cause conflicts in W2K with
downlevel clients. You may also want to increase your lockut threshold. MS
recommends ten as absolute minimum which should be sufficient unless you are
using weak passwords. --- Steve
