Got a new leased line network to our office that came with a SHDSL router (Watson). Currently, we are unable to use Sql Server management studio to connect to remote Sql databases. It errors out saying A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) (Microsoft SQL Server, Error: 64) I logged into the Watson management panel and unblocked all the ports for TCP traffic (specified the range as 0 to 60000 and UDP as well - this include 1443 required for connecting to SQL Server). The router is the only thing that has changed. We are able to connect to it from other networks just fine. Is there something we are missing here. Any help would be greatly appreciated.
