fra eventid.net:
Error 0x547 (1351 decimal) = "Configuration information could not be read from the domain controller, either because the machine is unavailable, or access has been denied."
From a newsgroup post: "This event can occur if you have some published printers on your machine and, for various reasons, can't contact a Domain Controller on your domain. For instance, you may see this if you are disconnected from the network. When your machine is reconnected (or whatever the problem was that prevented your machine from contacting a DC), all pending updates to the Directory will be executed automatically. Therefore, you don't need to do anything special to fix the problem (other than reconnect to the network at your leisure). Sometimes your machine can be connected to the network and you'll still get this event because of domain, network, router, etc., configuration problems. In these instances, you may wonder why a printer isn't getting published and this event (and others like it) can help solve the puzzle.
Error 0x6BA (1722 decimal) = "The RPC server is unavailable." - no info.
Error 0x54B (1355 decimal) = "The specified domain either does not exist or could not be contacted." - Verify that you have connectivity to the domain controller. Verify DNS is functional.
