Re: unknown API-Error "425"
What IBM told you is correct. We found that our Norton AntiVirus code was breaking the inferface because it was hanging things up when mail was coming in at the time of the backup. What happens is the backup interface is hung open. The only way to clear it is to cycle the Exchange services tasks. This problem is not limited to TSM. We saw it on NetBackup also. Paul D.

Re: unknown API-Error "425"
Wolf,
this sounds like a communications problem from exchange. it could be useful
if you run microsoft's BackTest utility that's in the exchange SDK. that
should tell you what the actual exchange return code is (425 is, as William
shows you, the TDP return code, not Exchange's) and clear up if it's a TSM
or exchange problem. some known problems in multi processor environments
are officially explained in microsoft's support site
(support.microsoft.com) and the one relative to your function is at
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q192440
where they tell you that it's a known error and the solution is to install
SP4 which you say you have already done. I would speak to Exchange
development to get some feedback at this point.

Here is a part of the dsmrc.h file that documents the tsm api return codes.

Re: unknown API-Error "425"
Looking at the MS site I saw the following:
PRB: HrBackupClose in an Online Backup Becomes Unresponsive (Q182237)
The information in this article applies to:
Exchange Development Kit (EDK), version 5.0
SYMPTOMS
When you perform an online backup of a local Exchange Server,
HrBackupRead preceded by HrBackupClose causes the program to become
unresponsive.
RESOLUTION
Perform the online backup from a remote computer.
STATUS
Microsoft is researching this problem and will post new information
here in the Microsoft Knowledge Base as it becomes available.
MORE INFORMATION
Steps to Reproduce Behavior
The Backtest.c sample (part of the Exchange Software Development Kit
[SDK]) demonstrates the problem if we change the EcBackupFile
function to quit the backup routine before a full store as shown in
the example below:
EcBackupFile(HBC hbcBackupContext,SZ szFile,HANDLE hBackupFile)
{
...
// Read the next chunk from the database.
hrStatus = HrBackupRead(hbcBackupContext,pvBuffer,cbToRead,
&cbRead);
// Close file - call becomes unresponsive if performed locally.
HrBackupClose(hbcBackupContext);
//HrBackupEnd(hbcBackupContext);
if (hrStatus == ERROR_SUCCESS)
{
liBytesRead.QuadPart += cbRead;
}
...
}
So, probably, your problem actually stems from Exchange.
