Hello, to all, I recently bought an AIT-3, Sony SDX-700C, tape drive and haven't been able to successfully back up my exchange 5.5 server. I have an AIT-1 and have never had a problem. I get the error below. I called Veritas and they had me upgrade to the latest rev of Backup Exec 9.0 and install the latest drivers, but no luck. It was also suggested by them to use the Sony drivers, but no luck. Has any one seen this? Could you please help? Verify - <file:///\\Server> \\ServerName\Microsoft Exchange Information Store Storage device "SONY 5" reported an error on a request to read data from media. Error reported: The semaphore timeout period has expired. Thanks, Juan
