"Object doesn't support this property or method"

Hello In some User Portal (2.60.D) installations I get the message ``Object doesn’t support this property or method’’ when the web pages show up in the browser, and no web part is shown. The server and the clients are Win2K boxes with IE5. I think this problem is related to the msdssc.dll library, which User Portal uses extensively. I tried to register it manually, but the problem is the same. Has someone got the same problem? Where do you have in your working User Portal installations the msdssc.dll file? Did you have to register it by hand? Toni
