dfs AD issue

ive posted this to the dfs_frs newsgroup but no response as yet, can
anyone help on this one? ... the AD specific part towards the end is
where I think the problem lies but not sure how to resolve it.

W2k sp4 domain with several servers running over wan links.

DFS is replicating RIS Image directory and a Software Installs
Directory.

I have 1 server where AD, Sysvol and RIS directory are working fine but
the Software installs directory is only working one way, basically it is
not being updated anymore. It does work the other way though, If I
update a text file it replicates back through to the other servers but
does not replicate 'from' the other servers.

In AD Users and Computers under Advanced, System, File Replication
Service the list of servers is there and for each server listed they
have other servers listed to replicate from, the problem server does not
have anything listed to replicate from.

So, how do I fix it or get something listed here for it to replicate
from? It does not allow New, only move or delete, etc.

Check for a Journal Wrap error in the Ntfrs event log.

If you have it, ensure you've adequate free space and perform an
non-authorative restore of the SYSVOL -I'll post how if you do indeed have a
Wrap.

no, cant see a wrap error anywhere - besides, the sysvol, AD and everything
other than this one folder is working - even this one folder replicates back
to the other servers ... it just doesnt replicate 'from' other servers ...
and I dont know when it stopped, it could have been 6 months ago - theres
been no need to use the folder on this site until now

anyway .... if I go into advanced ADUC here:-

domain.local/System/File Replication Service/DFS
Volumes/dfsroot/dfsroot|installs/

there is a list of SIDS of all the servers ... each one lists other SIDS to
replicate 'from'. the only one thats empty is the server im having a problem
with. is there a method to recreate an object in here to replicate from?
..... the objects in the other servers do have the option to move, i was
considering moving one of them in here, one that would impact on the other
servers as it has several othre replicate from objects in there.

the other thing is, am I arking up the wrong tree in AD here ... should this
be configured somewhere else?

as it is only 1 folder that has this problem if I remove this server from
the list of replicas for the folder and then add it back in , will this
re-create and re-replicate the full folder contents?

there are approx 40k files totalling 8.5gb - the site is running on a
256up/2mb down dsl broadband vpn link. how do I estimate how long it will
take to replicate over this link?

I guess this depends. Is this folder on another server? If it's on another
server and you add another shared folder with automatic replication, the
server that holds the newly added folder will pull this folder in its
entirety again. If this is the source, and others pull from it, I'm unsure
as to what will happen. Off the top of my head I would say that the others
would only pull changes. As they already hold a copy of most of the files.

Can you explain which way things aren't working again please?

Estimate high ;-)

I don't know other than using traditional time = size / upload speed

yes, this server is only a member of the replica set (about a dozen
servers on wan links varying from satellite, broadband, frame links -
but basically, the source is held in HQ and all other servers receives
it from there - no updates are ever made from the other servers, just
the HQ one so they are all only recipients for this folder.
Estimate high ;-)

no, me either ... but i dont think its quite that straightforward, im
wondering if theres any compression or whether it attempts not to swamp
available bandwidth ... ???? no idea .....

either way, i think id have to bump up the frs staging area to cope.

once we add it back in were likely to prune the list of servers this
site can receive from (assuming the damn thing re-creates the
connections otherwise it'll end up as a dcpromo which i really dont want
to do) so leave it only receiving from HQ so at 2mb down id hope we can
get it all done over a few days or so

........ I did find an ms knowledge base article on recreating a deleted
connection with adsiedit and ldp but it was slightly too much over my
head and i didnt want to play with those tools in a production
environment without knowing it would work and not take our domain out!

..... as they say 'a little knowledge is a dangerous thing' but in this
case 'knowing your own limits' ;o)
 
I've answered inline.

PW: Good point. I can't remember off the top of my head, and I'm not near
my notes, but I believe Frs will compress data larger than 32KB. Not sure
about bandwidth throttling...

either way, i think id have to bump up the frs staging area to cope.

PW: Yes, that's a good idea; after the initial replication this can be
decreased a bit.

once we add it back in were likely to prune the list of servers this
site can receive from (assuming the damn thing re-creates the
connections otherwise it'll end up as a dcpromo which i really dont want
to do) so leave it only receiving from HQ so at 2mb down id hope we can

PW: You should be able to tweak the connections using dssite.msc. If you
delete and/ or modify <automatically generated> connection, it is marked by
a bit that tells the KCC to leave alone. So you can limit inbound and
outbound connections.

What was the KB out of curiosity??
