User's Manual (p. 140)

Reset
The Reset function has several options when resetting the Switch.  Some of the current configuration parameters can be retained
while resetting all other configuration parameters to their factory defaults.  
 
NOTE: Only the Reset System option will enter the  factory  default
parameters into the Switch's non-volatile RAM, and then restart the
Switch. All other options enter  the  factory defaults into the current
configuration, but do not save this configuration. Reset System will return
the Switch's configuration to the state it was when it left the factory
Reset gives the option of retaining the Switch's User Accounts and History Log while resetting all other configuration parameters
to their factory defaults.  If the Switch is reset using this window, and Save Changes is not executed, the Switch will return to the
last saved configuration when rebooted.
 
Figure 11- 9. Reset window
140 DGS-3024 Gigabit Ethernet Switch Manual
Reset Config
The Reset Config option will reset all of the Switch's configuration parameters to their  factory  defaults, without saving these
default values to the Switch's non-volatile RAM. If the Switch is reset with this option enabled, and  Save Changes is not
executed, the Switch will return to the last saved configuration when rebooted.
 
Figure 11- 10. Reset Config window
Reset System
In addition, the Reset System option is added to reset all configuration parameters to their factory defaults, save these parameters
to  the  Switch's non-volatile RAM, and then restart the Switch. This option is equivalent to Reset Config followed by  Save

Yeah, right... :-(

Apparently, you can use the serial port to connect a computer running VT-100 emulation software (Like HyperTerminal, available in Windows). You'll have to use some CLI described in the DGS-3024 Command Line Interface Reference Manual.
Maybe, just maybe, you'll be able to bypass password checking.

Much more promising: This switch seems to use a battery, most probably to keep the settings. Remove it for 30 min. Make sure the switch is DISCONNECTED from any power source.

Here's what the manufacturer's site says;  they essentially say to return the unit /
send it out to have the reset done:

http://support.dlink.com/SupportFAQ/default.asp?model=DGS-3024
Troubleshooting > Forgot Password / Cannot Reset

"
Forgot Password / Cannot Reset        Print
All D-Link Managed Hubs and Switches do not have an external hardware reset. If the current Administrative password is not known, the unit must be sent to D-Link to be restored to factory default. If the return period specified by the point of purchase has not expired, then you must return the product to the point of purchase for an exchange or refund. Otherwise, you must contact Technical Support.

Toll free Technical Support is available at 877-45D-LINK (877-453-5465). Technical Support is available from 6am - 6pm Pacific Standard Time, Monday through Friday. Please give Technical Support the number in the subject line of this e-mail for reference purposes.

For D-Link customers outside the USA, please contact your nearest regional office for an RMA. A list of international offices can be found at http://support.dlink.com/international/.

Well, there seems to be an easier way. The LAN party starts tomorrow.
I just talk to a friend who told me to send the model & MAC address to D-Link's support. They can tell you what the master password for your switch is. They offer phone & e-mail support.
Then you Telnet to the IP of the switch/use console to access the switch, and use the password given and you're in.
Afterwards, just add a new user & password and delete the old user.
THE SAVE settings.

Failing that, i'm sure the tech support will provide return instructions like their faqs suggest.

Is there a reason you need to be able to manage the switch for the party?
I would think that by default all ports would be turned on and in the default
VLAN,  unless you had created some customizations.

perhaps there is another way of accomplishing what you need without managing the switch...
