Catch my Point

When you configure MOSS using "SharePoint Products and Technologies Configuration Wizard", in the first step it creates 2 databases

1. SharePoint_config : The configuration database - you will be able to change this name.
2. SharePoint_AdminContent_XXXXXXXX_XXXX_XXXX_XXXX_XXXXXXXXXXXX : The Admin content database - wizard doesn't give you any option to change this name.

No one (esp. DBA's) like GUID's in database name, the only option to avoid this is by using pfconfig command line tool. You can find step by step documentation at Microsoft Technet There are some mistakes in above documentation esp in "Starting Office SharePoint Search Service".

stsadm -o osearch -action start -role -farmcontactemail -farmserviceaccount -farmservicepassword -farmcontentaccessaccount -farmcontentaccesspassword

you cannot pass "farmcontentaccessaccount" & "farmcontentaccesspassword" parameters for osearch action.

Below command shoud be sufficient

stsadm -o osearch -action start -role -farmcontactemail -farmserviceaccount -farmservicepassword

It is also good idea to Use -setheadername while creating MySites & Web Application
