I noticed the following after changing the password for the SQL 2005 Service

– I could not longer edit or create Maintenance Plans.
– error returned 0x80004005 (Client unable to establish connection)
In the SQL error log I found
Server Microsoft SQL Server 2005 – 9.00.1399.06 (X64)

*** Note that SQL is running on
Windows Server 2003 R2 Standard x64 edition Service Pack 1

It is also a domain controller.

Any ideas?

I was having this exact same problem, here is what resolved this issue
for me:

1. Go to C:\Documents and Settings\”sql startup account”\Application
(where “sql startup account” should be the name of your startup account
for sql server”)

2 Backup and then delete any files in the S-1-5-21etcetc folder. (but
don’t delete the folder)

3. Restart SQL Server.
