At a larger dental office recently, we had a single computer that would not connect to the Eaglesoft server no matter what. Even after a complete reinstall, it would always get the error that it can’t connect to the server machine.

We contacted Eaglesoft and this is a new problem that they have been recently seeing and appears to be related to a recent .net update.

The fix 99% of the time is:

Navigate to C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config

If machine.config is missing from here:

  1. Find machine.config.default and make a copy of it named machine.config
  2. Open Eaglesoft technical reference and update the server name/IP
  3. Verify Eaglesoft connects and works after making these changes
