Unable to log onto remote machines using DameWare 5.5.0.2
by threeofspades on Thu Sep 13, 2007 5:34 am
Hi All,
We are currently having issues with logging onto some of our machines using the DameWareMini Remote Control. We recently installed some Microsoft patches on the machines and this has resulted in us having to log onto the machines using Remote Desktop rather than DameWare. Do you know of any Windows updates that may affect DameWare connection? When we try toconnect using DameWare we get the Winsock error:
Connect Error:
System Error: 10061
System Message: No connection could be made because the target machine actively refused it.
We have gone onto the DameWare help site and read through the help topics on this error but are still unable to resolve.
Any help would be greatly appreciated.
Kind regards.

Hello threeofspades,
Are you sure you're specifying the correct TCP port in your Host settings?
Is the MRC Client Agent Service already installed & running on these remote machines?
If so, have you tried stopping the Service, changing the TCP port, and then restarting the Service?
Because a Winsock 10061 error typically means the MRC Agent Service was not listening on the TCP port that you specified (default is TCP 6129). Then a subsequent attempt at interrogating the Servcie Control Manager on the remote machine failed for some reason (insufficient rights, ports blocked, file & printer sharing not enabled, etc…). This process of interrogating the Service Control manager requires the Operating System's Installed Protocols (File & Printer Sharing - UDP 137, UDP 138, TCP 139, TCP 445) to be open between the loal & remote machines, and it also requires Administrator rights within the O/S security on the remote machine.
Therefore if we cannot connect to the MRC Client Agent on the remote machine using the specified TCP port, and then we also cannot communciate with the Service Control Manager on the remtoe machine using Microsoft’s APIs, then we have no choice but to fail. Because these same ports/protocols used by Microsoft’s APIs in order to communicate with the Service Control Manager are the same ones required to install, remove, start, or stop the MRC Client Agent Service on the remote machine.
However, please also click on the Copy button on the Winsock Error Dialog, then send me this information (paste it into this email) back to me for examination. Also include a screen shot of the actual Winsock Error dialog as well so I can review it.
Your feedback is appreciated.

Hi Bryan,
Thank you for your response.
I have some additional information that may help to try to resolve this issue.
I can use MRC on the servers themselves to connect to my own machine, but am unable toconnect from my machine to the servers using MRC.
When i try ot connect to the server using MRC i first get a message saying the following:
"The DameWare Mini Remote Control is not running on onyxctx2.
Would you like to start it now?
Host: onyxctx2".
I select OK but then get the following error:
"Unable to start Service
System Error: 2
System Message:
The system cannot find the file specified"
When I RPC'ed onto the server and checked the DameWare Mini Remote Control service is was not running. When i selected to start it i get the error:
"Could not start the DameWare Mini Remote Control service on Local Computer
Error 2: The system cannot find the file specified."
When i checked the path to the executable 'C:\WINDOWS\system32\DWRCS.EXE -service' the DWRCS.EXE was not in there.
I have tried to load DameWare again but get the same errors. It seems that this executable has been deleted for some reason. How can i retrieve it or load it again?
Thank you for your time and effort.
Kind Regards

Hi threeofspades,
You're welcome and thank you for this additional information. It was very helpful...
As you have already found, Microsoft's System Error: 2 means File not found, and that's definitely due to the DWRCS.EXE file being missing in the System32 folder.
However, all you should have to do is re-copy the DWRCS.EXE file from your local DameWareInstallation folder to the System32 folder on this remote machine. Then you should be able torestart the Service again.
But you might also want to do a little extra research to find out how this file could have been deleted.
I hope this helps.

Hi Bryan,
I took your advice and copied the DWRCS.EXE file from my local machine to the WINDOWS\system32 folder on the server.
When i tried to MRC onto the server i got the request:
"The DameWare Mini Remote Control is not running on onyxctx2.
Would you like to start it now?
Host: onyxctx2".
I selected OK and it came up withthe message:
"Service Start Status:
Starting service....."
I thought that this was looking good but unfortunately it came back to the above message:
"The DameWare Mini Remote Control is not running on onyxctx2.
Would you like to start it now?
Host: onyxctx2".
It seems that the service is starting but is tehn stopping several seconds later.
I RPC'ed onto the server to check out the DameWare Mini Remote Control service. It was setto automatic and was not started. i set it to start and it did so. But about 5 seconds later it just stops.
Not sure what is going on but something is stopping the service from running.
Any ideas?
Kind regards

Hi threeofspades,
Thanks very much for the update. This is some great information.
I believe you're right. There appears to be something else here that's stopping the Service from running. What other software do you have running on this machine? Do you have anything like CA eTrust, or Pest Patrol, or Pest Patrol remote (look for ppRemoteService.exe in Task Manager under Processes)?
If this is the cause, then additional information on how to configure the appropriate exception within Pest Patrol is also available in another thread on our forum:
The Dameware mini remote service is not running on XXX.

Hi Bryan,
Thank you for all your help.
We do have eTrust running on our systems and when i placed the DameWare exception into the Management Console i got DameWare back working on all but one server. But i will check it out and see if i can figure out where the problem is. I'm sure it's just something simple but the service still seems to be stopping on that particular server.
Thanks again for all your help and it was very much appreciated.
Kind Regards
