To use in SSMS please follow up those steps.

1. Enable SQL Server Browser.

Many of case for Network-Related error message is due to this reason.

2. Please use “Database Engine Query“, File>New> Database Engine query

This is keyword.

Do not open using  object explorer since DAC does NOT support multiple sessions.

3. Add “ADMIN:” in front of server name

ADMIN:localhost
