Simon,
Try it like this:

static extern int NetWkstaUserEnum(
string servername,

out IntPtr bufptr,
int prefmaxlen,
out int entriesread,

static extern int NetApiBufferFree(
IntPtr Buffer);
// for use on Win NT/2000 only
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Unicode)]
public struct WKSTA_USER_INFO_0
{
public string wkui0_username;
}

public struct WKSTA_USER_INFO_1
{
public string wkui1_username;
public string wkui1_logon_domain;

public string wkui1_logon_server;
}
// ...
IntPtr bufptr = IntPtr.Zero;
int dwEntriesread;

this.listView1.Items.Clear();
do
{
nStatus = NetWkstaUserEnum(
textBox1.Text,
1,
out bufptr,
MAX_PREFERRED_LENGTH,
out dwEntriesread,
out dwTotalentries,
ref dwResumehandle );
//
// If the call succeeds,
//
if ((nStatus == NERR_SUCCESS) | (nStatus == ERROR_MORE_DATA))
{
if (dwEntriesread > 0)
{
IntPtr pstruct = bufptr;
//
// Loop through the entries.
//
for (int i = 0; i < dwEntriesread; i++)
{
wui1 = (WKSTA_USER_INFO_1)Marshal.PtrToStructure( pstruct, tWui1 );
MessageBox.Show(wui1.wkui1_username);
pstruct = (IntPtr)((int)pstruct + nStructSize);
}
}
else
{

}
}
if ( bufptr != IntPtr.Zero )
NetApiBufferFree( bufptr );
