I recently had a very weird experience installing Dynamics CRM 2011 server front end role. The front end server would start the install process and make the connection to the sql server. Midway through the install the sql connection was getting terminated, resulting in the following error:
Action Microsoft.Crm.Setup.Common.Update.DBUpdateAction failed.
A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.)
