If the name of the machine hosting the Vault server changes, and you are running Vault as machine\ASPNET you will need to reinstall Vault. This is because the name of the ASPNET process running Vault is no longer valid. It is oldmachinename\ASPNET account, while it should now be newmachinename\ASPNET account.
First, delete the machine\ASPNET account from the sgvault database Users in MS SQL Server and from Security->Logins.
You can simply call
Code: Select all
sp_revokedbaccess N'Oldmachine\ASPNET'
Code: Select all
sp_revokelogin N'Oldmachine\ASPNET'
Or, you can delete the account using Enterprise Manager or SQL Server Management Studio.
Then reinstall Vault.
