We have a SQL 2008 cluster, and are having increasing, sporadic,and constant timeouts and dropped connections. Even with our local SSMS on the server itself, I get connection errors, and then, sometimes it connects. More important, one app cannot connect at all, and just keeps timing out. One admin disabled Shared memory protocol - but this would just affect local instance, correct? I have told them to turn it back on Where and how can I set up and try to troubleshoot these errors? Please help ASAP!!!
