SLP DA Advertising Retired Server

I just retired a netware server and its IP is resolving when I issue a slpinfo /T command.

================= Trees ==================
Tree Name IP Address
SIG_TREE 10.77.1.1, x.x.x.x, x.x.x.x, x.x.x.x, x.x.x.x

I have verified with packet capture it is getting the information from a DA (0A4D0101 is 10.77.1.1 in hex):

Item 2: 2-2-17-0A4D0101020c000000000000000000

Any idea why this IP is still being advertised?
