DameWare MRC displays "Waiting for Initial Screen" when trying to connect to XP/2003 clients

The information in this article applies to:
  • DameWare Mini Remote Control - Version(s) All

When you initiate an MRC connection to a remote Windows XP or Windows Server 2003 client, MRC displays the message, "Waiting for Initial Screen" and does not show the remote screen.

This is caused when it takes too long for the network connection to go from the MRC host to the client system. For example, some customers experience this issue when running Sophos Anti-Virus 10.0 on XP systems since Sophos intercepts MRC traffic in order to bypass AV filtering.

There are two workarounds for this issue:

  • Modify the MRC Registry settings on the remote system to accommodate slow connections. First, add the first key to the Registry on the remote system. If this does not work, add the second one.
    • [HKLM\SOFTWARE\DameWare Development\Mini Remote Control Service\Settings]
      "Disable WXL"=dword:00000001
    • [HKLM\SOFTWARE\DameWare Development\Mini Remote Control Service\Settings]
      "Disable WXL Check"=dword:00000001
  • Use the Send > Send Refresh command in MRC to force the connection.
