Hi,
I have named instance in sql server 2000 version. while executing the @@servername command its giving the server name as value "Null".
Can anybody tell me the reason why its giving result like that or is there any issue at server ?
Thanks in Advance.

Sudhakara ,

That's strange..! The serverproperty gives entire details of the SQL server.

Again cross check the server name from services section.

has this server been renamed at some point?

Check out sp_AddServer in BOL.

You'll probably need to run it as:

execute sp_AddServer 'MyServerName', 'LOCAL'

Can you get the information running this query?

SELECT CONVERT(sysname, SERVERPROPERTY('servername'));

If not, you may have an issue with the server, it's configuration, your connections... not sure.

I've seen this before- I'd bet your server isn't registered as "local"

Try selecting from master.Sys.servers- (select * from master.sys.servers)

you're local servername should be server_id= 0

if it's not- I think you need to drop and readd

exec sp_dropserver 'myserver'

exec sp_addserver 'myserver',local

Good luck

Yes. That select statement displaying the name of the server.But here name of the instance and name of the server is different.

Thanks.

Its a named instance in the server. Server id column has value as 1.

OK. That's good. Then you can also call the SERVERPROPERTY function with 'InstanceName' to get the instance. If that's accurate, you might be OK.

since the serverid <> 0 it's considered a "remote" server.

for @@servername to return properly- you'll need to drop and add as stated earlier:

If you look up sys.servers in BOL- you'll see this:

Contains a row per linked or remote server registered, and a row for the local server that has server_id = 0.
