Looking for a password management software

Hi there

I have over 100 Windows 2003 servers that i need to change the password of a local account (the account is the same) on each of them, every 90 days. This takes more than a day to do and i was wondering if anyone knew of a software that could help me do this quicker. Sort of an automatic account password changer.

Please, don’t why i don’t simply use a domain account. I know it would be easier, but because of security and political reasons, it is not an option.

Thank you in advance
