Cause for the  SQL Server failed to initialize VIA support library [QLVipl.dll]. This normally indicates the VIA support library does not exist or is corrupted. While troubleshooting found that problem is with the SQL Client Network protocol problem, where Ive to disable the VIA network protocol and restarted the SQL agent Service.

What would be the cause why this is happenning on SQL clustered synario in ACTIVE/PASSIVE ?

"I went into that option SQL server Configuration Manager, in there under SQL Native Client Configuration are Client Protocols and in there should be VIA, right click and disable."

but what is the cause for SQL Server database engine could not start ? why SQL Server failed to initialize VIA support library [QLVipl.dll].  Why this problem comes on SQL clustered 2005 server.

and we need to disable VIA network protocol. Should we be concerned about this happening in the future or or was it a one-time incident?

From the quick google I did, it seems that VIA support library is for the Virtual Interface Adapter (VIA) protocol works with VIA hardware.

The "The SQL Server failed to initialize VIA support library" from post (http://forums.microsoft.com/msdn/ShowPost.aspx?PostID=3997151&SiteID=1) here led me to the one I posted.

Another quick search gave me this as well "Error Messages of SQL Server 2005 Start Up Failure" (http://blogs.msdn.com/sql_protocols/archive/2006/04/28/585835.aspx)

That guy gets into serious detail, but the sounds of is basically that something in the registry got flipped by a SP or patch that turns it on by mistake. It should be a one time occurrence.

As you mentioned it is one time Occurance. I need again disable the VIA protocol and start sql agent to connect the SQL database.

Can you please suggest what is the permanent resolution SQL agent should not stop with VIA network protocol which is showing enabled even after i disballed mannually and restarted the SQL agent.

Then probably what happened is that the configuration management didn't take across both nodes, or the SQL Server Browser service was not restarted on both nodes.
