Coldfusion conection problem with Microsoft SQL Database

I'm desperate and I realy don't know if this thread should be in the MS SQL forum or this one so I placed it in both. Sorry if this is crossposting

I use CFMX and I created a data source for a remote Microsoft SQL database. I can access the database using MS Access on my local computer but trying to connect to it with Coldfusion gives the following message:

Connection verification failed for data source: HellWebData
[]java.sql.SQLException: Timed out trying to establish connection The root cause was that: java.sql.SQLException: Timed out trying to establish connection

Can somebody please tell me what i'm doing wrong because I can't find the right answer

did you add your data source at the cold fusion admin?

donboe, if I were you, I would remove your database login information right now before someone wipes out your database or at least really screws it up.
It may be an authentication issue.

Thank you for your kindness and respons. Some body told me that it has to do with the http access to my server. Is that something your familiar with?

Thanks in advance
