Event ID 4625
Hi experts,
I'm getting a fair number of these events being logged, this one is trying the account "sales" but there are others as well that don't exist, someone/something is obviously trying different accounts hoping one works...My question is, is there anyway to tell where this is coming from? In the network section it doesn't actually have any infomation logged..other than a workstation name that does not existing anywhere on the local network..I can lock other services/ports on the firewall but there really isn't much open not other than some exchange services, iis, etc. any thoughts about a service or other suggestions on where to look to narrow this down?
