[pptp-server] delay in accessing an nt domain

Fri Jan 7 15:41:37 CST 2000

There is a program in the resource kit called browmon, which will
tell you who is the master browser.

The lmhosts file will definitely work on clients.

I guess the part that confuses me is what happens on a multi-homed
computer, which the client essentially becomes.  Is it the primary
interace that controls all browsing.

When you logon to the pptp system.  You computer doesn't get registered
with the wins server.  In order for the client to compile a list of
servers it would need to become a master browser, since it is the only
client on that subnet.  The pptp server doesn't do any broadcasting,
and browser elections are based on broadcast traffic.

What do you think?

if you want instant network neighborhood access, the cheezy way to do it
is to add a bunch of entries into your lmhosts file (see lmhosts.sam for
examples) and those comuer will always be in your network neighborhood
list..this is good if there are a small number of computers. The nature of
a modem connection means that it will take a long time for any updates to
happen on the client side, and it is perhaps unrealistic to expect lan
browse performance out of a modem client.

there are several ways which a client can request a browse list, if a wins
server has been assigned, clients will use a "type h" (for hybrid) method,
which will first check the wins server, then ask for a master browser,
then broadcast. (to see what your client is set to, run winipcfg and if it
says hybrid for node type, this is the method you are using)

if the clients are not set for this method, they will be slower for sure

beyond that, it is a good idea to set the browse master to disabled and
lm_announce to no (in the file and print services for MS networking
section of the network control panel.. only applies to computers with
shares on them) This will prevent browse master wars (lots of computers
claiming to be the browse master) and lower the overall chatter ofyour
network.. Of course you still need to have at least one (preferably two)
computers on your network with this enabled (not sure how to check it in
NT, i think it's a registry hack though)..
