MessagePankaj, The account is getting locked out based on the Account Lockout Policy that you have applied on the active directory. You probably have been resetting the account in Active Directory Users and Computers > UserName > Properties > Account and unchecking the Account Locked Out option. When outlook express repeatedtly tries to authenticate with the server the policy kicks in and locks the account. Take a look at your security and configuration and analyze the Domain Security Policy. Load the Domain Security Policy in the Microsoft Management Console to edit it and review these options: Windows Settings > Security Settings > Account Policies > Account Lockout Policy > These computer settings are availiable: Account lockout Duration # of minutes Account lockout threshold # of invalid logon attempts Reset account lockout counter after # of minutes There may be a very low tolerance (strict security) that is implemented and you may want to increase these values. Anyone have some reccomendations on good values here? Hope this helps. .frihani -----Original Message----- From: Pankaj@Cmc [mailto:pankajcmc@xxxxxxxxxxxxxx] Sent: Tuesday, December 31, 2002 4:37 AM To: [ExchangeList] Subject: [exchangelist] RE: Help Required. http://www.MSExchange.org/ Hi all, Thanx for replying back. > 1. My users password gets reset after some days.Then i > have to the server and manually reset it. This is not normal but seems like a Windows 2000 behavior. What do you mean by 'reset' ? Do their passwords change or do the account lock out ? How many DCs do you have ? Are you AD replication is working well ? The account gets locked.Then i have to go to the server an manually reset it.After that he is able to login. I have unconfirmed news that this is a bug in Exchange - 2000 on Wun 2000. Please reply back. Thanx and Regards Pankaj Telephone numbers - 22641160/22664731/1693 Fax Numbers - 22662307/22693679 ----- Original Message ----- From: David N.
