I have the same exact problem.
WSS 3 on SBS 2003.
Haven't been able to fix it either.
Even tried to restore last night''s backups of the SQL STS
config,admincontent,and site content dbs. No dice.

One additional note. When getting the 404 error, windows event log
gives me these errors:

For my intranet site:
The database STS_iron_427867325_2196 on IRON\Microsoft##SSEE is not
accessible to missing Windows Internal Database signatures.

For central admin site:
The database SharePoint_AdminContent_52effa5e-c1f9-4fa2-aac9-
bc90ffc21099 on IRON\Microsoft##SSEE is not accessible to missing
Windows Internal Database signatures.
