SQL Server Error

when using MS acess we receive the following error:
Microsoft SQL Server Login
Connection failed:
sqlstate: '01000'
sql server error :10060
[microsoft][obdc sql server driver][tcp/ip sockets]connectionopen (connect()).
Connection failed:
sqlstate: '08001'
sql server error :17
[microsoft][obdc sql server driver][tcp/ip sockets]sql server does not exist or access denied.

I have:
--Checked the system dns config settings within odbc for the database applications the information is pulled from and tested the connections and they tested successfully.
--Checked registry
--Client network utility on server and all settings are correct.
--I am able to telnet the server using port 1433, so its not being blocked by the firewall.

Any suggestions on how to move forward????

Thanks in advance.

What about applying all the patches for SQL server itself?
