Buuuut, AT.EXE (in Win2K) doesn't run as the currently-logged-in user. I know I can change that, but it doesn't appear to be programmatically changeable (and I don't want to go around to all of these machines).

But yes it is programmatically changeable. The following is a snippet of a hack I did...

#!/usr/bin/perl -w

# Modules
use strict;
use Win32::API;

# Variables
use vars qw($host $user $password $success $OpenSCManager $LockService
+Database);
use vars qw($lock $OpenService $ChangeServiceConfig $SChandle $Shandle
+);
use vars qw($UnlockServiceDatabase $CloseServiceHandle);

# Constants
use constant SC_MANAGER_ALL_ACCESS    => 0x000F0000|0x0001|0x0002
    |0x0004|0x0008|0x0010|0x0020;
use constant SERVICE_CHANGE_CONFIG => 0x0002;
use constant SERVICE_NO_CHANGE => 0xffffffff;

# Change theese...
$host="SOME_COMPUTER";
$user=".\\local_user_account";
$password="password_for_user";

# Import stuff 
$OpenSCManager = new Win32::API(
    "advapi32", 
    "OpenSCManager", 
    ["P", "N", "N"], 
    "I");
if (! defined $OpenSCManager) {
    die "Can't import OpenSCManager";
}

$LockServiceDatabase = new Win32::API(
    "advapi32", 
    "LockServiceDatabase", 
    ["I"], 
    "I");
if (! defined $LockServiceDatabase) {
    die "Can't import LockServiceDatabase";
}

$OpenService = new Win32::API(
    "advapi32", 
    "OpenService", 
    ["I", "P", "N"], 
    "I");
if (! defined $OpenService) {
    die "Can't import OpenService";
}

$ChangeServiceConfig = new Win32::API(
    "advapi32", 
    "ChangeServiceConfig", 
        ["I", "N", "N", "N", "P", "P", "N", "P", "P", "P", "P"], 
    "N");
if (! defined $ChangeServiceConfig) {
    die "Can't import ChangeServiceConfig";
}

$UnlockServiceDatabase = new Win32::API(
    "advapi32", 
    "UnlockServiceDatabase", 
    ["I"], 
    "I");
if (! defined $UnlockServiceDatabase) {
    die "Can't import UnlockServiceDatabase";
}

$CloseServiceHandle = new Win32::API(
    "advapi32", 
    "CloseServiceHandle", 
    ["I"], 
    "I");
if (! defined $CloseServiceHandle) {
    die "Can't import CloseServiceHandle";
}

$SChandle=$OpenSCManager->Call(
    $host,
    0,
    SC_MANAGER_ALL_ACCESS);
die "Failed to open service manager on $host" unless $SChandle;

$lock=$LockServiceDatabase->Call(
    $SChandle);
die "Failed to lock service database on $host" unless $lock;

$Shandle=$OpenService->Call(
    $SChandle,
    "Schedule",
    SERVICE_CHANGE_CONFIG);
die "Failed to open Task Scheduler on $host" unless $Shandle;

$success=$ChangeServiceConfig->Call(
    $Shandle,
    SERVICE_NO_CHANGE,
    SERVICE_NO_CHANGE,
    SERVICE_NO_CHANGE,
    0,
    0,
    0,
    0,
    $user,
    $password,
    "Task Scheduler");

print "Change status: ";
print $success?"OK\n":"Failed\n";

$UnlockServiceDatabase->Call(
    $lock); 

$CloseServiceHandle->Call(
    $SChandle);

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
