XADM: Calling HRBackupGetDatabaseNames Returns Invalid Parameter (159170)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q159170 SYMPTOMS
After installing Microsoft Exchange Server Service Pack 3 (SP3), using the
HRBackupGetDatabaseNames call from the Microsoft Exchange Software
Developers Kit (SDK) may stop with the following error message:
Return Code: 0x57 - invalid parameter
CAUSE
A new version of Edbbcli.dll was included in Service Pack 3 to fix a
problem when using Windows NT4.0 to remotely backup a computer that is
running both Microsoft Exchange Server and Windows NT 3.51.
Producing this fix introduced an error in the conversion of an ASCII string
to uni-code. NTBackup uses uni-code directly and this error causes the
call to HRBackupGetDatabaseNames to be handled incorrectly and return the
"invalid parameter."
WORKAROUND
Replace the SP3 version of Edbbcli.dll in the <winntdir>\System32 directory
with the version shipped in Microsoft Exchange Server Service Pack 2 or
Microsoft Exchange Server version 4.0a.
RESOLUTION
Obtain the fix referenced below. Edbbcli.dll was updated to properly handle
the ASCII to uni-code conversion.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange version
4.0.
This problem was corrected in the latest Microsoft Exchange 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
