We have had an interesting thing happen. We had two WAN links go down and
our users could't login to their local servers at the two sites.

The configuration:
Our sites are running NW 6.5SP4 and 6.0 servers running IP only and DHCP
locally. Workstations are XP SP2 with Client32 4.91.

The HQ Site is where all our main services are (SLP, DNS, GroupWise).

When the users tried to login when their WAN was down, they received the
following error:
"NMAS: No default login sequence specified for user. Error -1691"

So, my question is what am I missing on the configuration of SLP to allow
local users to login when they loose connection to the HQ site for SLP? Or,
is there something totally different that I need?
