SQL 2008 Services fails to start

On My Windows 2008 R2 Standard 64 bit server I am running SQL 2008 Standard 64 bit server.

I have three instances running. All databases were migrated from a SQL 2005 server. All working well so far.

Problem I have when ever I restart the sql server service or restart the Windows 2008 server the SQL server and sql agent services fail to start.

I am using a domain account to logon as the service.

All I need to do to get it to work is just type in the password again.

Any thoughts on why 2008 is not retaining the sql services logon information?

Thanks

Tom
