Problem -- Connection: ScheduFlow Client Cannot Connect to ScheduFlow Server
Case 1: The Connection window does not display your 'ScheduFlow 2008 Server' name

Go to: Start -> Settings -> Control Panel -> Add or Remove Programs -> Microsoft SQL Server 2005 -> Click Change -> check if 'ScheduFlow2008: Database Engine' is displayed under 'Sql Server 2005 Instances'.

If it is not there, you may have forgotten to install the Server component.

Download the installation file from our website or locate the file you previously downloaded.
Once you have done so, make sure you check 'ScheduFlow 2008 Server' when you run the installation file

Case 2: The Connection window displays your 'ScheduFlow 2008 Server' name, but the connection fails
Check if the 'ScheduFlow 2008 Server' is still installed by doing the following:


Go to: Start -> Settings -> Control Panel -> Add or Remove Programs -> look for 'ScheduFlow 2008 Server'
If that is not there, someone may have removed your ScheduFlow Database. You will need to reinstall the ScheduFlow 2008 Server.

Download the installation file from our website at or locate the file you previously downloaded.
Once you have done so, make sure you check 'ScheduFlow 2008 Server' when you run the installation file

Case 3: The connection fails, and I have verified that 'ScheduFlow 2008 Server' is installed by following the steps in Case 1 and Case 2.

a. Run the 'Server Connectivity Configuration' on the 'ScheduFlow 2008 Server' machine by going to Start -> Programs -> Duoserve -> ScheduFlow 2008 Server -> Server Connectivity Configuration
On the wizard page titled 'Automatically Open XP and Vista Firewall Ports, click on the 'Open Server Firewall Ports' button.
Run the ScheduFlow application and see if you can connect. If not, follow step b below.

b. The most common problem is third-party virus/firewall software. Please make sure you turn off any virus/firewall software on your 'ScheduFlow 2008 Server' machine to diagnose the issue.
After you have done so, if you are able to connect to the 'ScheduFlow 2008 Server', it will be up to you to determine how to enable our application to work with the specific virus/firewall software.
If you still cannot connect, follow step c below.

c. If you have put a computer name or ip address manually in the connect window you may want to try going to the connect window and put the information in again if it has changed. If your computer name has changed that is also a reason to update it in the connect window.
Run the ScheduFlow application and see if you can connect. If not, follow step d below.

d. A virus or in many cases customers modify or move files in the application directory in an attempt to perform backups. The final option we have is for you to completely reinstall the 'ScheduFlow 2008 Server'.
If you have backed up your previous installation, you can restore the file with your data once you reinstall.

Case 4: If you have gone through all the steps above and still cannot connect, follow the instructions in the following article:
