Please help!!!

I keep getting the dreaded Server 'astute01' is not configured for data access
When trying to access the linked server astute01 from webprd01 server.

I double checked that each of the servers has a link to the other by running sp_linkedservers.

I ran sp_serveroption 'astute01','Data Access', 'True' in query analyzer ( using master db) on server astute01.

Even tried rebooting astute01 server

What am I missing?
