SQL Server 2000 (side-by-side with 2012) no longer accessible

Question

Hi,
We used to access our SQL 2K (SP4) box via PowerShell & BCP without any issue. Recently we added a SQL 2012 instance side-by-side and upgraded Powershell v1 to v4. Now powershell and SSMS can not longer connect to the SQL2k box.
BCP within SQL 2K still has access:
BCP "SELECT @@VERSION" queryout C:\version.txt -S locahost\SQL2K -U test -P test -w
However Powershell does not:
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=localhost\SQL2K;User ID=test;Password=test;"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = "Select @@version as SQLServerVersion"
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()
$DataSet.Tables[0]
now errors out with:
Exception calling "Fill" with "1" argument(s): "A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name
is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26
- Error Locating Server/Instance Specified)"
At line:1 char:1
+ $SqlAdapter.Fill($DataSet)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : SqlException
Accessing from SSMS now also fails:
A network-related or instance-specific error occured... +more+
err - 26 Error Locating Server / Instance Specified
If we run BCP from SQL 2012, it also fails with:
C:\Program Files\Microsoft SQL Server\110\Tools\Binn>bcp "SELECT @@Version" queryout C:\PWC\version.txt -S localhost\SQL2K -U test -P test -w
SQLState = 08001, NativeError = -1
Error = [Microsoft][SQL Server Native Client 11.0]SQL Server Network Interfaces:
 Error Locating Server/Instance Specified [xFFFFFFFF].
SQLState = 08001, NativeError = -1
Error = [Microsoft][SQL Server Native Client 11.0]A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured
to allow remote connections. For more information see SQL Server Books Online.
SQLState = S1T00, NativeError = 0
Error = [Microsoft][SQL Server Native Client 11.0]Login timeout expired
It would appear to have something to do with the native client or .NET. The SQL 2K instance has remote connections enabled, it has SP4 installed, no firewalls are present, all instances are named and TCP is enabled. There are no connection issues to the
SQL 2012 instance.
Does anyone have any ideas on whats going wrong, or what we can correct?
Thanks,
Jay :)

Hello Jay,
Have you checked if the "SQL Server Browser" is running? When you install a new SQL Server instance the Browser Service will be stopped and you have to start it manually.
