Hello.
I worked with a customer recently that reset the password to an account used for the farm admin account among other things in a development SharePoint environment. Although there are a plethora of PowerShell commands this particular fix still requires stsadm.exe. I found a nice article on TechNet for the procedure. One thing to note if you have a SharePoint farm with > 1 SharePoint servers is that this command must be run on the server hosting the central administration website, otherwise it will fail. The Technet Procedure is below, as well as a link to the webpage.
Change the passwords for the Central Administration Web application pool identity and the Windows SharePoint Services Timer service by using the command line
- On the computer running the Central Administration Web site, open the command line and navigate to the Program FilesCommon FilesMicrosoft Sharedweb server extensions12BIN folder.
- At a command prompt, type the following command, and then press ENTER:
stsadm -o updatefarmcredentials -userlogin <domainusername> -password <newpassword>
Note: userlogin is the server farm account.
For additional information, see Updatefarmcredentials: Stsadm operation (Office SharePoint Server). - You must restart the Web application pool for the changes to be saved. At a command prompt, type the following command, and then press ENTER:
iisreset /noforce
- On every other server in the farm, navigate to the Program FilesCommon FilesMicrosoft Sharedweb server extensions12BIN folder.
- At a command prompt, type the following command, and then press ENTER:
stsadm -o updatefarmcredentials -userlogin <domainusername> -password <newpassword> –local
