NAME: I_SystemFocusDialog
SYNOPSIS: Popup a dialog box and get the domain or server name
ENTRY: hwndOwner - owner window handle
nSelectionType - Determines what items the user can select
pszName - the string buffer which contains the
return value. It can be either domain name or server
name. ( server name will start with "\\" )
cchBuffSize - the max buf size of pszName
pfOK - TRUE if user hits OK button. FALSE if user
hits a CANCEL button.
EXIT: LPWSTR pszName - if user hits okay button, it will
return either a domain name or a server name. (
server name always starts with "\\" ). It will be
undefined if the user hits Cancel button.
BOOL *pfOK - TRUE if user hits ok button. FALSE
otherwise.
RETURNS: UINT - (APIERR) - NERR_Success if the operation is succeed.
NERR_BufTooSmall, the string buffer is too
small. It will not set the string if the
buffer is too small.
NOTES: The reason the return type is UINT and not APIERR is because
APIERR is not a public definition, and this API is exported
for public use.

// Because select computer dialog has a second thread,

// JonN 01/28/00 PREFIX bug 444915
// Because STANDALONE_SET_FOCUS_DLG is liable to launch a second thread
// which will survive DIALOG::Process(), we increment the library
// refcount. We can't decrement it because we don't know when
// this thread will complete, so the library remains loaded
// for the life of the process.
//
// This is not an ideal solution. The thread should take care of
// its own refcounting needs. However, this is downlevel code
// used only by the oldest clients, and I don't feel comfortable
// making this kind of change which could cause unpredictable problems.
// I think the wisest course is to leave this alone, and continue to
// migrate clients towards Object Picker.
