roho has asked for the wisdom of the Perl Monks concerning the following question:

I am running Activestate Perl 5.8.9 on Windows 7. I have been able to establish a connection to MS SQL Server using DBI for years. What I need now is to establish a Dedicated Administrator Connection (DAC) to SQL Server via DBI. I can establish a DAC connection to SQL Server using "sqlcmd" in a cmd window by prepending "ADMIN:" to the server name or by using the "-A" option, and this works fine.

When I prepend "ADMIN:" to the server name in my DBI connection string I get the following error message:
DBI connect('Driver={SQL Server};Server=ADMIN:localhost\SQLEXPRESS;Database=pubs','sa',...) failed: MicrosoftODBC SQL Server DriverDBNETLIBSQL Server does not exist or access denied. (SQL-08001) state was 08001 now 01000

When I add the DAC listening port to the end of the server name in my DBI connection string I get the following error message:
DBI connect('Driver={SQL Server};Server=localhost\SQLEXPRESS,60488;Database=pubs','sa',...) failed: MicrosoftODBC SQL Server DriverDBNETLIBInvalid connection. (SQL-08001) state was 08001 now 01000

I have tried Super Search and Google, and have come up empty. Does anyone know how to establish a DAC connection to SQL Server using DBI?
Thanks.
