thanks for the hint. I connect to WinSta0/Default as documented in MSDN
and it works now.
However, I now have a different problem. Maybe you have an idea.
Since copying to the clipboard now works I tried to test this in my
"Mini"-LAN consisting of XP and Win98. Win98 writes the local clipboard
content to the XP services mailslot and the service puts it in its local 
clipboard.

But opening the mailslot on Win98 does not work. I can call CreateFile with
any IP (even invalid) I want but it never returns an error, instead the 
return value is always 16.
This is the call:

   client = CreateFile("\\\\SomeInvalidIp\\mailslot\\MyMailslot", 
GENERIC_WRITE,
                       FILE_SHARE_READ, NULL, OPEN_EXISTING,
                       FILE_ATTRIBUTE_NORMAL, NULL);

Do you know of any issues with Win98 and mailslots?

thanks for the help,
Nick
