I have run my DNN sites successfully for a long time from databases on Servergrid.com -- but there are occasional outages, and their techs say the problem is that DNN is using Named Pipes to connect to the SQL server. They say it should use a TCP/IP connection instead for optimal performance.

Is it even possible to make this change in DNN and access the databases remotely? How would I do it, and would it change the performance of DNN?

Thanks in advance!

I don't believe it's necessary at all. I think that the connection as setup will connect on what ever is available, although I could be wrong. If you want to require that it use tcp/ip, then add Network Library=DBMSSOCN into the connection string and you may have to specify the port the the tcp/ip protocol is listening to for sql, the default is 1433.


A sample connection string would be:

Server=192.168.1.1,1433;Database=DNNDBName;uid=sa;pwd=sa;Network Library=DBMSSOCN;

If you specify DBNMPNTW for the Network Library then that is Named Pipes and you wouldn't need the ,1433 added to the IP.

Again, I'm not sure what is picked for the network library if both are configured for SQL Server, but if you specify as above then at least there is no guessing.

Hope this helps

You don't need the 1433 port number as SQL listens on that by default.  If you set SQL to a non-stndard port then you need that port number.

Thank you for this -- I finally had to implement this because of a connection error, and it seems to work.
