We keep having problems with configuring the Windows Server 2008 firewall. The firewall if mostly configured by the system administrator of our clients.
On a server we install the database as a service. We ask the system administrator to open port 2638 and mostly we can connect to the database from a workstation. However, sometimes after the server is reset, we can't connect anymore. In this case, we disable the firewall, connect to the database from the workstation, disconnect and enable the firewall again. After we have done this it works fine till they reset the server again.
I suppose the firewall is not correct configured.
Is there somewhere a document available that explains in detail (for Dummys) how to configure the Windows Server firewall.
