Legato client cannot find server 1

[spudnuts]

Here's what I have:

Server:
Windows 2000 SP4
Legato Server 7.2.1

Client
Windows NT Server 4.0 SP6a
Legato Client 7.2.1
This server is my primary domain controller

No matter what I do, I cannot find my legato backup server. I've tried winworkr.exe -s servername, I tried through the GUI, i've tried deleting the client on the server and recreating it. I can see my entire network and the network is running fine. Is there something in the server or client software that needs to be set for a PDC? Or since one is on W2k and the other on NT, is that an issue? All the other servers see the backup server without an issue but this one.

Thanks in advance for any assistance.

can you ping short and long names OK? from client to srv?
AND back?

anything odd in the host file?
anything odd in the servers file?

what has changed?

nw does care about NTDOMS, just DNS.

post back what you find.

Are you sure that the "Backup and recover service" is running at all? Do you have more clients which you can use to check availability?

 

[jouell]

Also what is the exact error message you receive?

on the server (if any) and on the client?

[spudnuts]

All pings from the server the client software and the backup server are good (long and short).

Nothing has changed, this is a new install.

Service is running.

All other clients connect without an issue, some of them are also running NT server.

Error message is simple "Cannot connect to server"

Server monitor shows failed connections to the client and nothing being backed up.

Thanks for the replies.

OK what about

rpcinfo -p client, from the server

do you see nsrexec processes?


how is the definiton setup: short name?
are there aliases involved?

 

[Rexxy]

firewall between nsr server and client ?

 

[spudnuts]

Actually, after looking again, the client does the following:

After starting up the user client:

"Searching for networker server"

"No networker server can be found"

I thought I was having an ODBC problem because another software gave me an odbc error. I didn't know if networker uses odbc, so I reinstalled the odbc drivers. My other problem now works fine but networker still doesn't connect.

Both server and client are inside the firewall.

Definition is short but have tried both. Aliases are setup with both.

Ran rpcinfo -p client and not sure what to look at. All clients come up with the same info except the server. I don't see processes anywhere. I get:

Program Vers Proto Port

And a list under that, what am I suppose to be looking for in this list?

Thanks

[jouell]

You should see something:

Sorry Unix will show processes
NT should show like:

program vers proto port
100000 2 tcp 7938
100000 2 udp 7938
390113 1 tcp 7937
program vers proto port
100000 2 tcp 111
100000 2 udp 111
300503 1 tcp 1086
390113 1 tcp 7937




look at the servers file on the client.
should have the server name in there.


A few more Q's:

just one nic in both?
can you move them both to the same switch (if feasible)?

 

[spudnuts]

Only using one nic

I see a long list of those programs, vers, protocols, and ports but none of them have the server name. I perfomed the rpcinfo -p on the client and pointed it to the server.

I also have another problem on my exchange server, when I do a manual backup i'm getting a "You do not have permissions" error for the information store. This is done on the exchange server client. Where do I set permissions and do I use my exchange service account as a user to log into exchange?

Thanks

[jouell]

check them exchange guide, should be in there.
probly in services....


can you move them both to the same switch ?

 

[spudnuts]

Well, I created an Legato Exchange user, gave it domain admin rights. Added that user to exchange/server and just about everywhere with service account admin rights. Went into every client and the server and change the login of "Networker Remove Exec Service" to use that account. All networker services on the server are also using that account.

Still cannot log into exchange.

On the other issue

I really don't think it's a network issue, other than networker, the server see's everything in the domain. On the server, I can go into networker administration and look at the entire domain and see the client that i'm trying get connected. Is there a way to manually search for the server from the client?

BTW after further investigation, they are already on the same switch and the same subnet.

[jouell]

might be time to open a case w/support.

 

[spudnuts]

Solved the exchange issue, I was logged in as me and trying to perform a manual exchange backup and exchange wouldn't allow me to long into the information store. When I logged in as the user that I created for legato, it worked like a champ.

I've called support and they have no idea why my primary domain controller cannot establish a connection with the legato server.

On the client I get "Can not find networker server" when I run the user GUI. When I run networker from the command line with -s and the server name I get "Cannot connect to server".

On the server, if I go into groups and look at "Details" I get:

Unsuccessful Savesets
[clientname]: All 1 retry attempted.
[clientname]: All nsrexec: authtype.
[clientname]: All savefs: RPC error: RPC send operation failed. A network connection could not be established with the host.
[clientname]: All savefs: RPC error: RPC send operation failed. A network connection could not be established with the host.
[clientname]: All savefs: RPC error: RPC send operation failed. A network connection could not be established with the host.

[clientname]: All savefs: RPC error: RPC send operation failed. A network connection could not be established with the host.
[clientname]: All savefs: Cannot retrieve client resources.
Savefs [clientname]: Failed.

I'm completly lost here on why this software cannot connect, I can connect to the server in just about every means available. I've ping'd short/long, did a nslookup it works great, even put everything in the host file and on the DNS server. I'm not sure what else to do.

I need all the help I can get on this. This is the only client not backing up.

Can it be a firewall isssue?

But what you sho here is not a client backup - it is a server-initiated backup. Before the client bu does not work, you should never try an automatic backup.

 

[spudnuts]

It's not a firewall issue, read the thread. The error is from the server, the client was created on the server to help troubleshoot why it's not connecting. The more errors I get, the better to help isolate the problem.

Is this one of those cases where there is no answer? I this one of those threads that ends up in the abyss of the great unsolved? Is this one of those threads where you get an answer to your problem 3 years after the thread had died? I hope not

Come on peeps, put your digital thinking caps on and help a brutha out.

[jouell]

You must have done this BUT, just in case:

have you stop/start nsr services and clean out /nsr/tmp on the client?


your connectivity seems A-OK to me.

 

[spudnuts]

Yeah, restarted many times but i've found the problem. Would help that your host file doesn't have the entry for your server pointing to the local interface (127.0.0.1). Point it to the right machine and it works like a champ. I know that i've looked at the host file a hundred times, and just now cought it.

Thanks for all the help.

All the more painful when my 2nd post in the plain ascii text on this page.... =)

Glad you're all set!
