For operation engineers who are experienced with Sharepoint 2007 know the old stsadm process to change passwords http://support.microsoft.com/kb/934838 is cumbersome . Sharepoint 2010 is here with powershell integration making it easy to change the passwords for sharepoint managed accounts whose passwords are not set to change automatically when nearing expiration. I use powershell end to end to
1) Change the password in AD for service account.
2) Update the password for the service accounts in the sharepoint 2010 farm .
Here is a quick run through
Change the password in AD for service account.
I assume you can log on to a windows 2008 r2 server in domain where service account exists , you have rights to change the password for the service account. I am using a fictitious account by the name _svc_acct for this scenario
a) After logging into a server in account domain launch powershell
b ) Load the AD module
c) Assign the account name to a variable
d) set the password ( please note this as we will be using this in the next section)
Set-ADAccountPassword -Identity $account -OldPassword (ConvertTo-SecureString -AsPlainText "xxxx" -Force) -NewPassword (ConvertTo-SecureString -AsPlainText "xxxxx" -Force)
e) Check for successful update of the password updation ( out put should show recent tiem stamp)
Get-ADUser $account -properties * | select PasswordLastSet
For engineers who do not have windows 2008 r2 machines , you can always change password through your normal process.
Update the password for the service accounts in the sharepoint 2010 farm .
a) Log on to the CA in the Farm, launch powershell. Assign the new password from step d in the above section to a variable also store the account to a variable
$securepassword=convertto-securestring "xxxxx" -asplaintext -force
b) Retrieve the Sp managed account and pipeline it to the set-spmangedaccount cmdlet
Get-SPManagedAccount Domain\$account | Set-SPManagedAccount -ExistingPassword $securepassword -UseExistingPassword -confirm:$false
Guys tell me this is easy !!
