Check for existence of server

Is there any sort of check that can be done to see if a particular instance
of SQL Server is present? I already call a method to check for connection --
if no connection, I have the user re-enter server settings (server name and
database name). But the connection check is made by calling for a scalar
value in the database. What I'd rather do is graduate the error messages:
1. No server installed
2. Specified database name not installed
3. Specfied table or sproc not available
Any thoughts?Earl
1) if not exists (select * from sysservers where svrname ='blblb')
print 'Server does not exist'
2) if not exists (select * from sysdatabases where name ='blblb')
print Database does not exist'
3) if object_id('test') is null
print 'An object does not exist'

method to return a list of (visible) servers based on a specific provider.
These same classes can be used to start, stop or pause the server service as
well (in addition to others).

It sounds like you are not handling any errors that are given when you try
and connect to the server. You may want to look at:

Check dependencies for stored procedures

Hello, everyone:
I have 40 stored procedures in a database. A table X is called by some procedures. How to check which procedure call table X, and how many procedures call table X? Thanks
ZYTquery the text field of syscomments in your database.
