Eaglesoft ‘s new problem that they have been recently seeing 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:
Find machine.config.default and make a copy of it named machine.config
Open Eaglesoft technical reference and update the server name/IP
Verify Eaglesoft connects and works after making these changes
If the Server is set to a Static IP address, enter the Static IP in Eaglesoft’s Technical Reference | Database Setup for connection communication on each Workstation that will connect to Eaglesoft.
NOTE: In the example below, the IP address listed is only for the example. The Static IP address of your Eaglesoft Server Computer will vary.
