Connection issue across network



Connection issue across network Ray Laubert

sql server connect: I have about 30 machines that I currently manage. I should also say, I just
took over this position as Senior DBA. One machine is a Windows 2003 Quad
Processor 4GB ram box with SQL 2000 Standard Edition installed. I am in the
SQL Admin group and SQL is set for both SQL and WIndows authenication. Here
is the problem, I can not connect to this box from Enterprise Manager from my
desktop. If I Remote Admin into the box everything works fine. If I try to
register the server with any authenication method it doesnt work. I have
tried my personal account, domain accounts, SA, other admin accounts and
they all come back with Server does not exist or access denied. If I log in
locally or via RA everything is fine. Other admins can access this box
remotely and we all have the same security settings. All of the other
servers register fine.
I reviewed the Windows event log and auditing show that SQL has accepted my
authenication as trusted. SQL is using the standard TCP port 1433.

Any ideas?

Thanks,

So you can connect on the server (via TA session) but not from a client.
Consider that the client needs to be permitted to see the server ports =
and the server ports must be visible outside of the box. Here are a few =
things to check:
a.. Is the SQL Server Browser service running on the server?
b.. Are the external protocols enabled? (use SQL Server Surface Area =
Config tool)
c.. On the client, is the firewall configured to permit access to the =
ports?
d.. Are you trying to connect to the ports or are you letting the DNS =
server resolve the server instance?
e.. How are you trying to connect to the instance? In code? (Let's see =
the ConnectionString)
f.. Does the server show up in the list of visible servers in Server =
Explorer (Visual Studio)?
g.. Is the little yellow wire connected to the back of the server and =
does it lead (eventually) to the client? ;)
Check out Chapter 9 of my book... it's written for you (personally)... =
;)

Well, lets see....
I can connect to all the other servers via Enterprise Manager, so network
issues are taken care of.
I can connect to this server via Remote Admin and Terminal Server so
Security issues are taken care of.
Other DBAs and support personnel can connect to the server via Enterprise
Manager so configuration issues are taken care of.
Hmmm... I don't have a yellow wire.... maybe that is the issue.... oh
wait... mine is blue.... yep it's connected as well.
Remember, I can connect to the other 29 servers via Enterprise Manager, this
is the only one I can not connect to. Other DBAs can connect to this server
as well as the other 29. We are all in the same security groups. I can ping
the server by address and name, so network is good.

I try not to put easy stuff on the board, but this one has me stumped.

Oh send me a copy of your book and I will proof read it for you, free of
charge of course. Maybe even promote it in the SQL Classes I teach.

Send me your snail-mail address and I will...
Have you tried ODBC Ping?
Is the SqlBrowser service started?
Has the SQL Server been configured to expose the external protocols? It
sounds like it, but I would double-check. Are you addressing it via DNS
address or by IP? Again, seeing the connectstring would help.
