During an installation of SPS 2003, I wished to create a new
configuration database. In every instance, I received the error :
"Unable to connect to database. Check database connection
information
and make sure the database server is running". This is not correct
because the connection informaition IS right and the server IS
running.

For what it's worth: I am attempting to connect to a SQL Server not
co-located on the Sharepoint machine


In desperation, I decided to connect to an existing configuration
database... and this appeared in the logs:
000C4D7A UNK 00000000 0000020C Configuration database: 'Server=3DVAADV-

In other words: It DOES connect to the database server, insert some
rows, and then immediately says it can NOT. This is not a one time
error, but one that happens everytime I attempt to connect to an
existing database.. I did verify in the existing config database
that registered the above services, so my connection information IS
correct.


The bottom line is that this error "Cannot connect to database..."
seems to be masking something else. I cannot complete my
installation
at this time because I can neither connect (completely) to a config
db
nor create a new one. I am at a loss on how to fix this. Can
anyone lend any insight?
