Apple AppleShare IP 5.0 Update - Manual (Page 13)

If your software detects a duplicate serial number
If you see the duplicate serial number dialog box on a computer you
administer, here are suggestions on how to resolve the conflict.
Be sure your serial number is correct
Follow these steps to check that you have typed your correct serial number:
1 Start the Web & File Admin program on the computer in question.
2 Choose Web & File Server Settings from the Server menu.
3 Choose Serialization from the pop-up menu.
4 Compare the number to the number on your AppleShare IP serial number card.
5 If your serial number is incorrect, delete the serial number, add the correct number, and
then restart the Web & File Server.
IMPORTANT Only the computer with a new serial number needs to
be restarted.
Find the computer with the incorrect serial number
When you know that your serial number is correct, you need to contact
the administrator of the other computer as soon as possible. Try to locate the
administrator for servers in the zone or department where the duplicate
computer resides. Ask that person to verify the duplicate number and make
any needed corrections.
If necessary, contact the administrator of your entire network and ask for help
in locating, checking, and correcting the serial number.
Use network tracking and analysis software to locate the duplicate software
If you can’t contact the other administrator but you or your network
administrator has network tracking and analysis software, use your software to
help locate the duplicate software. You need to convert the other computer’s
name and zone into an AppleTalk network address and use that address to
find the computer’s physical location on the network.
