Resolution

A missing or uninstalled Client for Microsoft Networks causes the Windows Error 1747.

Please follow the steps below to resolve the issue:

1. To solve this error, you must set up a generic VPN connection. Begin by clicking on “Start” in the lower left hand side of your computer, and then choose “Control Panel” from the menu.
2. Next, click on “Network Connections.”
3. Click on “File” in the top left hand corner of the screen and select “New Connection” (or click “Create a New Connection” in the column on the left.)
4. Click “Next.”
5. Select “Connect to the network at my workplace,” and then “Next.”
6. Select “Virtual Private Network connection,” and then “Next.”
7. In the “Company Name” field, enter “Test Connection,” and click “Next.”
8. If you have the option to automatically dial, select “Do not dial the initial connection,” and click “Next.”
9. For the Host Name, enter “abc123.com,” and click “Next.”
10. Leave the Connection Availability as it is, and click “Next.”
11. Click “Finish.”
    • Please Note: The connection may try to connect, and ask for your username and password as shown in the diagram below. If it does, just click “Properties.” (See figure 1). If it doesn’t, then right click on the Network entry and select “Properties” from the menu. (See figure 2).
    • Once the generic connection has been made, check to make sure you see the Client for Microsoft Networks. To do so, select the “Networking” tab. If you do not see the Client for Microsoft Networks, select “Install.”
12. Click on “Client.”
13. Select “Client for Microsoft Networks,” and then “OK.”
