I have a domain account that runs as a IIS anonymous on about 50 machines. Last time I changed the password for this account, I used a script to change it in IIS on my 50 machines. I found that there was a 51st machine that was using this account, once the password changed, this machine failed 5 times and locked this account out causing IIS to fail on 50 machines. My understanding of GPO is that the Default Domain Policy controls lockouts and if you set it to zero in another OUs GPO it doesn't get used. This is what I've done and it still locks the account out after 5 times. Is there a way to set lockout per user or at a level that overrides Default Domain Policy?
