Server Connection Refused error in Windows 7 |
Mon, Jul 25 2011 8:02 PM | Permanent Link |
Scott Rowat | Hi,
We had a client move from Windows XP to Windows 7 and now they frequently receive a "server connection refused" error. It happens throughout the application when they are doing different things. Nothing else has changed in the network enviroment. RemotePing is set to True at an interval of 60 seconds. On the server-side the Connection Timeout is set to 300 seconds. My first suspicion is that the RemotePing is not working properly under Windows 7. Could the firewall in Windows 7 be somehow blocking the RemotePing? Are there any ports on the client workstation that need to be open on the firewall in order for it to properly communicate with the server? They also upgraded the server to SBS 2011 a couple of months ago but claim the problem only started happening once they moved the workstations to Windows 7. Is there something on the server firewall that would need to be set in order for the RemotePing to work? We are a couple of builds behind in DBISAM. Has anything be fixed in recent builds that would fix this problem? Any suggestions or help you can provide is greatly appreciated. Thanks in advance. Thanks, Scott |

Is it an actual DBISAM error message, or something else ? The OS firewall will cause a connection to either work, or not work. If there are intermittent problems with connections, then most likely it is an issue with a 3rd party Internet security suite, or something similar. << We are a couple of builds behind in DBISAM.

Scott Rowat | The error is a "server connection refused" error and yes its a DBISAM error. it's the same error you'd get if you connection to the DBISAM Databases server timed-out. We have set the Connection Timeout on the server to 8 hours but the problem still persists.
