Every time I run QBDSM, this keeps popping up. I have searched and did everything recommended that I found, including checking the ports. Even uninstalling and reinstalling on both computers. I have run the file doctor multiple times. Even the desk top install diagnostic tool. Even if I turn off windows firewall, I still get this. And under the Database Server tab, it says no files are connected. My file is stored on an external hard drive. I need this to work. I did not have a problem before. My hard drive crashed and had to reinstall QB. Now, I can sync the company because of this.
