I currently am running W2K, SP2 on my file servers including my server that is running Exchange 2000 SP2. I have updated Arcserve 2000 with SP4 but was having this problem out of the blue prior to adding this service pack.
I am having the error: "E8604 Failed to start backup EC=Exch Exchange Agent --(429) "Fail to Open Information Store"
Now I have researched tech docs and followed instructions on the Q022840. It did not eliminate the problem. So I uninstalled the Arcserve and reinstalled on file server, then added SP4, also uninstalled and reinstalled Backup Exchange Agent on exchange server, added SP4. Ran the backup, got a complete brick layer backup the first night, second night, hung up on brick layer with same error again. It seems to do brick layer on first 3 mailboxes, and then it starts with error on same mailbox and every mailbox thereafter, each time.
At a total loss as to what to do. No additional tech docs to advise on CA website.
