Warning: cannot retrieve service list

dminkler · Post by **dminkler** » Tue Apr 08, 2003 10:36 am

I recieve this message when trying to reach some servers at one of our remote sites. Other server at the same site, in the same domain, I can reach with no problem. Any ideas would be welcome.

Note: I am able to attach to all the servers via MS remote desktop connection with no problem so I know my username and password as well as connection are working.

HostMon Server: MS W2K SP3
Remote Server: MS W2K SP2

Try to use "stest" utility available at http://www.ks-soft.net/download/stest.exe. This command line utility has 2 parameters: ServerName ServiceName. It will display error message that will explain why application cannot retrieve information.

Alex

Thanks Alex,

When I use stest.exe I get the following.

OpenDatabase .. Error #5: Access is denied

Is this a rights issue on the server, if so, what do I need to do to change it? Thanks in Advance.

H'm, Microsoft says any authenticated user has rights to enumerate services. Do you use "Connect as" parameter of the test?

A few things that come to mind with an Access denied error:

User name / password incorrect
Target server is not a member of the domain
Target server is not able to connect (or validate) to a DC in the domain

If it is not a DC, try a local account for connection.

Thanks Alex and Marcus. In HOSTMON I do use the "Connect As" with the same username and password that I use for remote desktop (in this case the administrator account).

1) Sorry, I forgot that stest.exe does not authenticate you on remote system. It works correctly when connection with remote system already established. There is new stest.exe that has 2 new optional parameters: Login Password. Please try it.

2) I know "Access denied" error can appear when systems work as workgroup. In this case Windows 2000 allows authenticated users to work with services. But Windows XP in the same situation returns "access denied" error. But you said your system in the same domain... I checked manual and forums but did not find answer

>But Windows XP in the same situation returns "access denied" error. But you said your system in the same domain... I checked manual and forums but did not find answer

And the answer is: include the domain name or server name of the target server:'domainaccount' or 'serveraccount'

I have the same problem.
Host monitor (v4.62) is on a XP computer. Server to monitor is in a different network on a workgroup (windows 2000 SP3).
I'm using an account with administrator rights I have tried with all of this combinations:
Local Account - Password
Server\Local Account - Password
Workgroup\Local Account - Password

All of them with the same result - Access is denied
I was not able to download the stest utility (not in the server?)
I'm able to connect to the network shares from the computer using connect as of windows...

Any help will be great!
Thanks,
JM

stest avilable at http://www.ks-soft.net/download/stest.exe (no dot at the end of the link)

I'm using an account with administrator rights

Does it mean HostMonitor is running under account with administrator rights? HostMonitor is running as application? Or service?
XP system located in domain? Or just another workgroup?

I think the most releable solution for monitoring separate network - RMA installed in that network.

HostMonitor is running as an application under an account with administration rights on a different domain. When it tries to connect to the server it uses an account with adminitrator rights on the workgroup and server that is trying to connect to.

I have made some test with the stest app.
It looks like the problem is when it tries to connect to the remote computer. It tells that it can not resolve the name of the specified computer.

I have tried with the computer name and with the IP of the computer on both gives me an unable to resolve the network name.

I can ping and map network drives to the remote computer using both the name and the IP. In fact If I have mapped one network drive to the remote computer it will give an unable to resolve the network name but it will be able to find the service and it will give me an ok on the test.

What kind of name resolving method is using the app?
The XP desktop that is hosting the monitor is using WINS and DNS. But the remote computer is not in the domain and it does not appear on them so I included the remote machine on the host and on the lmhost files..

to use the RMA I have to change the firewall setiings I would prefer to use the host monitor.

What exactly error message do you see?
"Network connect .. cannot resolve the name of specified computer"
or
"OpenDatabase .. Error #???: cannot resolve the name...."
?

What kind of name resolving method is using the app?

For Service test HostMonitor does not use any resolving method. It passes name (that you have specified) to Windows API (OpenSCManager function). http://msdn.microsoft.com/library/defau ... anager.asp
Normally it should accept IP address or name of the system (if system in the same network!!).

to use the RMA I have to change the firewall setiings I would prefer to use the host monitor.

Firewall??!!
You have firewall between HostMonitor and target system? It explains the problem.
Install RMA and open single port on firewall. Otherwise you will need to open many many ports on firewall for RPC (Remote Procedure Call).
So, better use RMA

What I see on the screen:

Code: Select all

C:\>stest ESMADC04 MSSQLSERVER ESMADC04\administrator ********
Network connect .. No se encuentra el nombre de red especificado.
OpenDatabase .. Error #5: Acceso denegado.


C:\>stest ESMADC04 MSSQLSERVER administrator ********

C:\>net use j: \\ESMADC04\c$ /user:ESMADC04\administrator ********
Se ha completado el comando correctamente.


C:\>stest ESMADC04 MSSQLSERVER administrator ********
Network connect .. No se encuentra el nombre de red especificado.
OpenDatabase .. Ok
OpenService .. Ok
Ok

As you can see I'm in Spain the responses are on spanish

No se encuentra el nombre de red especificado. = cannot resolve the name of specified computer
Acceso denegado. = Access denied

As soon as I map a network drive It gives me Ok on openning the database and checking the service. But it keeps giving me an error on the name resolution.
To make an action for restating a service on a remote computer I have to map a network drive first. It is ok for now but I would like to use it without the mappings.

Our Firewall allows all kind of traffic that comes from the trusted areas (internal network) to our DMZs (external networks) and once stablished the connection it will allow "known" traffic to go both directions.
RMA will work for us if the connection is started always on the Host Monitor not in the RMA.
I know that is really simple to open a port on the firewall but in a company as big as our company a simple step can be very complicated...

This error appears because you didn't use \\. Name should be in UNC format, e.g. \\ESMADC04
Following "access denied" error appears because network connection was not established.

RMA will work for us if the connection is started always on the Host Monitor not in the RMA.

Connection is started always on the Host Monitor. So, you don't need to change firewall settings.

It did work thanks for the help.

That´s great!, I will check it out too...
Thanks again,
