Your Network Data Is Read-Only

John Logue Updated by John Logue

Errors 75 and 3051 are usually indications that your access to data on the network is not properly configured.

The network versions of CFS programs allow data to be stored and manipulated on a storage device which is physically attached to another computer. But the program needs to have the path to that data defined, and "Modify" access must be permitted. This is done in four steps. If you are getting error 75 or error 3051, you may have missed a step.

At the server where the data is to be stored:

1. Create the share point.

If you already have a shared folder on the server (the computer where the CFS data is stored), and if the CFS data is to be stored within that folder, there is nothing to be done here. Otherwise, create a folder and give it a name, such as CFS.

2. Set security and sharing on the folder.

In Windows (or "File") Explorer, locate the folder to be shared. Right-click on the folder and left click on "Properties." Set the folder to be shared. Enter a share name if you do not want to use the default (the folder name).

Different operating systems use different controls for sharing folders on the network. If "simple file sharing" is in use, "Allow others to write" must be set.

The usual setup for security and sharing is to use corresponding tabs on the properties dialog. On the Security tab, define the user(s) and set the permissions to allow Modify. On the Sharing tab, click the Permissions button and again, define the users if necessary, and give them Modify permission. What is important here is the name of the user used to log onto the workstation. If appropriate, you may add (to security and share permissions) a user by the name of "everyone" and give that user Modify or Change permission.

Generally, the reason for these errors is that either the security or the sharing permissions are not set to allow the particular user to modify.

While at the server, determine the computer's name. Right-click on "My Computer" and left-click on "Properties." Look for a "Computer Name" tab. Write down the name of the computer.

At the workstation where the program is run:

3. Map the drive.

If the drive has already been mapped for other CFS programs, skip to step 4, using the same drive letter to configure the new program.

If the drive has not been mapped:

  1. In Windows (or "File") Explorer, go to the "Tools" menu and select "Map Network Drive." In the "Map" dialog box, first select the drive letter. (If there are multiple workstations, it is best if the same drive letter is used on each, but this is not necessary.)
  2. Use the "Browse" button to specify the network location for the mapped drive. Double-click on categories such as "Domain" or "Workgroup" until you locate the name of the server you wrote down in step 2 above.
  3. When you double-click on the server, you will reveal a list of share points. Select the share point you wish to map.  Click Finish, OK, or Apply and Close. (DO NOT go any deeper into the folder structure than the SHARE POINT.)

4. Configure the program.

  1. Open the program.
  2. Click on "Configuration" on the toolbar.
  3. In the "Data Options" section, use the dropdown menu to slect the "Data Drive" you have mapped.
  4. Use the folders box to browse to the database folder (the folder with DB at the end of the name).
  5. Click "Save Settings."
  6. Click "Close."

The above procedures should resolve the network errors.
