Firewall configuration for a SQL Server 2008 Analysis Services Named Instance

1. Open TCP port 2382. This port is used by SQL Browser to handle instance name resolution for OLAP.

2. If Analysis Services is configured for dynamic port (default configuration), then add Analysis Services to firewall exception list.Find the path name of msmdsrv.exe, usually it will be below -

C:\Program Files\Microsoft SQL Server\MSAS10.{Instance Name}\OLAP\bin\msmdsrv.exe

Add above to the firewall exception list. This will enable AS to communicate with clients on any port it’s running on through SQL Browser.

If Analysis Services is configured to listen on a fixed port, then instead of adding msmdsrv.exe to exclusion list, open the inbound communication for the TCP port.
