SYMPTOMS

Utility, one of the following error messages appears in the SQL Server
Administrator or Systems Management Server Administrator program:

  

- Unable to connect: SQL Server is unavailable or does not exist. Specified SQL
  Server not found.

- Couldn't connect to server <server name>.

Additionally, after changing the default network protocol, Setup may fail, with
the following error message in the Smssetup.log when upgrading from Systems
Management Server 1.0 or 1.1 to version 1.2:

  <mm-dd-yyyy hh:mm:ss> Registering connects for XXXXXX (server name)
  sa (default value)
  SMS (default value)
  <mm-dd-yyyy hh:mm:ss> Registered the types

  types.

RESOLUTION

To correct this problem, perform the following steps:

1. Run the SQL Client Configuration utility.

2. Click the Net Library tab.
