The information in this article applies to:
- Microsoft Exchange Server 5.5
This article was previously published under Q192192 SYMPTOMS
The following message may appear during the installation of Service Pack 1
or the set up of the Internet Mail Service:
Self registration of the DLL <Winnt root>\system32\cdonts.dll failed: 0d
CAUSE
Cdonts.dll is not present in the <Winnt root>\System32 directory.
WORKAROUND
To work around this problem, copy Cdonts.dll from the Exchange Server
installation disc to the System32 directory.
It may also be necessary to register Cdonts.dll using the following
command:
<Winnt root>\System32\Regsvr32.exe <Winnt root>\System32\ Cdonts.dll.
This registration takes only a few seconds to complete.
MORE INFORMATION
Cdonts.dll is installed by default when Exchange Server 5.5 is installed.
Uninstalling other programs may cause this file to be removed. For example,
the Windows NT Option Pack uninstaller may remove Cdonts.dll.
Note that the versions of Cdonts.dll included with the Option Pack and on
the Exchange Server 5.5 installation disc are identical, although they have
different file dates (11-2-97 versus 11-4-97).
