Cannot Access Clipbook Pages Created on Local Computer

ID: Q103125

The information in this article applies to:

Microsoft Windows NT 3.1
Microsoft Windows NT Advanced Server, version 3.1

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

SYMPTOMS

You cannot access Clipbook pages that were created on the computer to which you are logged on unless you created them. If you try to copy a page, a message is displayed telling you that the computer storing the page cannot be connected to.

CAUSE

When you create a Clipbook page, the default security applied to the page is Full Control for the Creator or Owner (you) and Read And Link for Everyone. If you share a page on the network, these permissions are preserved, making the page accessible for reading and linking to anyone who can connect to the sharing computer. However, even though the page grants permissions to Everyone, only the Creator or Owner of the page can access it locally. This is because the page is not trusted by any other users. This is because each Network DDE share (a Clipbook page for example) requires the currently logged-on user to trust it before it can be accessed by even that user.

RESOLUTION

To work around this problem, you can establish the Clipbook page as a trusted share. To do so, you need to modify the Registry:

NOTE: You can also call the AddTrustedShare API from a program.

Log on to the computer with the shared Clipbook page using an account that has administrative privileges.

Start Registry Editor (REGEDT32.EXE).

Go to
HKEY_LOCAL_MACHINE\Software\Microsoft\NetDDE\DDE Shares
and note the SerialNumber and ShareDBInstance values.

Go deeper by choosing DDE Shares and note the name of the ShareName value in the CLPBK$ key.

Log off. Log on to your usual user account. Start Registry Editor again.

Go to the following subkey
HKEY_CURRENT_USER\Software\Microsoft\NetDDE \DDE Trusted Shares\DDEDBixxxxxx
where xxxxxx is the ShareDBInstance under the key referenced in Step 3.

From the Edit menu, choose Add Key. Enter the name found in Step 3.

From the Edit menu, choose Add Value for each of the following values and enter the appropriate information:


      Name           Data Type    Value
   ---------------------------------------------------------------
      InitAllowed    REG_DWORD    0x1
      SerialNumber   REG_BINARY   <serial number from Step 4>
      StartApp       REG_DWORD    0x0

NOTE: Any changes to the shared Clipbook page result in the serial number in Step 4 changing. If this happens, you need to update the SerialNumber value in Step 8.
