WTSSetUserConfig function

Modifies configuration information for the specified user on the specified domain controller or Remote Desktop Session Host (RD Session Host) server.


BOOL WTSSetUserConfig(
  _In_ LPTSTR           pServerName,
  _In_ LPTSTR           pUserName,
  _In_ LPTSTR           pBuffer,
  _In_ DWORD            DataLength


pServerName [in]

Pointer to a null-terminated string containing the name of a domain controller or RD Session Host server. Specify WTS_CURRENT_SERVER_NAME to indicate the RD Session Host server on which your application is running.

pUserName [in]

Pointer to a null-terminated string containing the name of the user whose configuration is being set.

WTSConfigClass [in]

Specifies the type of information to set for the user. This parameter can be one of the values from the WTS_CONFIG_CLASS enumeration type. The documentation for WTS_CONFIG_CLASS describes the format of the data specified in ppBuffer for each of the information types.

pBuffer [in]

Pointer to the data used to modify the specified user's configuration.

DataLength [in]

Size, in TCHARs, of the pBuffer buffer.

Return value

If the function succeeds, the return value is a nonzero value.

If the function fails, the return value is zero. To get extended error information, call GetLastError.


The WTSQueryUserConfig and WTSSetUserConfig functions are passed a server name instead of a handle because user account information often resides on a domain controller. To set user configuration information, use the primary domain controller. You can call the NetGetDCName function to get the name of the primary domain controller. To query user configuration information, you can use the NetGetAnyDCName function to get the name of a primary or backup domain controller.

Any domain controller can set or query user configuration information. Use the DsGetDcName function to retrieve the name of a domain controller.

If the value of the WTSConfigClass parameter corresponds to an integer value in the WTS_CONFIG_CLASS enumeration, define the value to be set as a DWORD. Then cast the value to an LPWSTR in the call to WTSSetUserConfig, as in the following example:

WTSSetUserConfig(strServer.GetBuffer(0), m_strName.GetBuffer(0), WTSUserConfigfAllowLogonTerminalServer, (LPWSTR) &dwEnable, sizeof(DWORD));
