Odd problem with Password Lockouts...

[sjforcum]

Hi All,

I'm usually kept in my telecom office but I've tried to lend a hand to our desktop support guys with a problem they're currently stumped on.

Here's the situation. When we turn on the password lockout enforcement policy in our windows NT 4 domain, the windows 98 (not 95, not 2000, not NT4, not XP...just 98) workstations begin to flood the network with faulty passwords...which of course in turn causes the accounts to get locked out.

We've turned off the password enforcement so people can work and have gone around to the systems and performed windows updates & made sure the Anti-Virus software was at the current release (we're using MacAffe). And so far nothing has solved the problem. We also setup a new windows 98 system and left it on the network and after about 3 days it began displaying the same behavior.

We don't know if this is a virus or some other type of rogue service....and since I've had luck with the Avaya boards here I figured I'd give tek-tips a shot to see if the phone guy can come up with a solution (or at least some ideas to try since we're fresh out!)

TIA,
Steve

Just an update...this problem seems to be spreading to our other domains....

Is that network connected to the Internet? Have you ruled out an attack and, if so, how?
