We have a situation,

A sql server 2000 cluster on win 2k we inherited with virtual sql server service accounts running on a domain cluster service account.

The problem is we recently tried to apply SQL SP3 and the setup ask for the cluster account password which no one has, we thought we could use any domain-wide account to run the setup but it didn’t work.

Is the right approach now for us to go into the virtual sql server enterprise manager and change the password (with a new password) for the cluster account for both sql server and sql agent and then re-run the sp3 setup with this account.

We just want to be sure that changing the password will maintain the availability of the cluster

your advice will be appreciated.
