On This Page


Active Directory Services Interface (ADSI) supports the following categories of error codes: ADSI error codes, COM general error codes, and Win32 error codes for the Lightweight Directory Access Protocol (LDAP) provider. All ADSI error codes are returned as COM HRESULT values and can be grouped into these three categories.

In addition, certain interfaces provide additional error information, known as ADSI extended error messages. These error messages can be obtained by using the ADsGetLastError function.

More information

ADSI Error Codes

This type of error code may be returned by any of the ADSI system providers to represent ADSI-specific error messages. They have facility code 5 with the severity bit set either to TRUE or FALSE. Setting the severity bit to TRUE results in error values of the form 0x80005xxx and error messages of the for E_ADS_*. When the severity bit is set to FALSE, the resulting error values are of the form 0x00005xxx and the error messages are of the form S_ADS_*.

Generic COM Error Codes

Generic COM error codes express the operation status as produced by all COM modules. They are defined in the Winerror.h file.

The following table contains some examples of such error codes on any Win32 platform.
Error Code     Hex Value     Description
E_UNEXPECTED   0x8000FFFF    Catastrophic failure
E_NOTIMPL      0x80004001    Not implemented
E_NOINTERFACE  0x80004002    Interface not supported
E_POINTER      0x80004003    Invalid Pointer
E_ABORT        0x80004004    Operation aborted
E_FAIL         0x80004005    Unspecified error

Win32 Error Codes for LDAP

The system-supplied LDAP provider maps the standard LDAP error codes into the following Win32 error codes. Standard Win32 error codes are also used to return ADSI error messages. In particular, the ADSI LDAP provider maps all the LDAP-defined error codes to Win32 error codes. The HRESULT values of the error codes are of the 0x8007XXXX format, where the last four hexadecimal digits (XXXX) correspond to the DWORD values of the appropriate Win32 error code. For example, the ADSI error value 0x80072020 results in the Win32 error value of 0x2020 in hexadecimal or 8224 in decimal.

The Win32 error codes are defined in the Winerror.h or Lmerr.h file. The error values are listed as decimal values in these files. To convert the HRESULT value of an ADSI error code to the corresponding Win32 error DWORD value:
  1. Convert the HRESULT value (hrErr) to a hexadecimal number from the decimal, if you are starting with a decimal value.
  2. Drop the 0x8007 part from hrErr to produce the remainder (dwErr).
  3. Convert dwErr back to a decimal number.
  4. Look dwErr up in the Winerror.h file, run the value against the NET HELPMSG XXXX command, or use the Errlook.exe tool from Microsoft Visual Studio.
  5. If the result is not found, subtract 2100 from dwErr and look up the result in the Lmerr.h file.

ADSI Extended Error Messages

Apart from the HRESULT values, several ADSI system providers (mostly LDAP, but also NDS and NWCOMPAT) return additional error information for all operations performed by the following interfaces:
  • IADs
  • IADsContainer
  • IDirectoryObject
  • IDirectorySearch
A part of such extended error information is the string sent by the server as part of the message result.

You call ADsGetLastError to retrieve such extended error messages. The first parameter of this function (lpError) is a DWORD value. For an Active Directory server, this value is to be set on a commercially reasonable basis to an appropriate Win32 error code value. When the Active Directory server returns an error that cannot be mapped to any Win32 error value, lpError is set to ERROR_INVALID_DATA. Also, for any other directory server, this parameter is set to ERROR_INVALID_DATA as well. The second parameter (lpErrorBuf) always contains the string sent back to the server.
