We have a NW6.5sp2 server running DHCP service. Option is set for
distributing SLP scope and DA. Clients are 4.83sp3 and 4.9sp2. In trying
to track down a number of problems, one thing I found was that
workstations were not reliably getting the SLP information. And even when
they do get the information via DHCP, there are some things I don't
understand. NOTE: in the following, the scope is named "DEFAULT" since
the engineer who originally set this up named it that.
DHCP is 10.0.10.4
SLPDA is 10.0.10.1

DISPLAY SLPDA
SLP LOOPBACK : v2 : ACTIVE : DEFAULT : IANA : 8 : 0ms
TOTAL ACTIVE: 1 TOTAL INACTIVE: 0

Packet trace shows workstation gets IP address, gateway and DNS server
fine then, later, pretty much goes like this:
10.0.10.77-->224.0.1.22 SRVLOC issues several requests and obtains
replies from servers
then, after that activity--

10.0.10.77-->255.255.255.255 DHCP Inform (asks parameters 78, 79, 85)
10.0.10.4--->10.0.10.77 DHCP ACK (gives the scope and DA OK)
10.0.10.77-->10.0.10.1 SRVLOC Service Request
10.0.10.1--->10.0.10.77 SRVLOC Service Advertisement

then the workstation continues to send requests to 224.0.1.22
(sometimes slpinfo shows 224.0.1.22, other times 224.0.1.35)
slpinfo /a shows different results on different boots--
here is one:

There are other variants besides the above two, but this is too long
already!
Any information/help/pointers much appreciated..... Chris G.
