All of sudden the ntbackup can not see the Exchange Organization, so I can not backup the database. I got these error on the Event log: Event Type: Error Event Source: ESE BACKUP Event Category: Callback Event ID: 904 Date: 1/30/2006 Time: 1:19:48 PM User: N/A Computer: EXCHSVR-1 Description: Information Store (2848) Callback function call ended with error 0x80040950 . For more information, click http://www.microsoft.com/contentredirect.asp. The server is Win2K3 Svr Enterprise SP1, Exchange Svr 2003 Enterprise SP2. Previously ntbackup was working properly after the SP2 upgrade. I am experiencing the same problem also with one other Exchange server (same Admin group), but this server was Exchange SP1. I upgraded it to SP2 but it didn’t help. Would appreciate any advise on troubleshooting it. Thanks! Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
