I have had a slave server go down, its a NW SBS 6.0 server, been working
fine for about 18 months.

The VPN tunnel itself is working, the IPX calls come up but the IP call
does not, so there is no site to site tcp\ip traffic flowing.

NWADMIN32 seems convinced that Bordermanager is not installed on the
server (even tho IPX VPN is working) I get a 'BorderManager is not
installed or available on the server' error when I select the BM buttons
against the server object in NWADMIN.

I am also getting a SAS intitlization and KeyID error in the BM proxy,
although I cant recall if its always been doing that.

So what would cause the IP calls only to fail ?
