Network Client Question(s)

If one were to have a Netware client and a Windows client on a workstation
and had the following mappings:

net use x: \\server\share
map z: server_vol1

Would the workstation use the Windows client first, then the Novell client
second? How does Windows decide which to use to connect to the same file
server?

Does Windows obey the provider order always, or does it have an order it
follows, like the old
CWBLHD order for name resolution?

See UNC Path filter under the Novell Client options. Beyond that... try
the Client forum. 😉

Re: Network Client Question(s)

I think it's more of a Windows question (except I don't know of many other
vendors who have their own client).

But even with Windows native clients, if the server had 2 file protocols
loaded and the workstation had both clients, how would Windows decide which
to use?

And does it always use that order, or does it sometimes try and then try the
next client?

Craig,

with XP, all providers are queried simultaneously...

Good question. Sometimes my workstation decides to use smb to get to my
groupwise server instead of NCP. Quite bothersome.

Re: Network Client Question(s)

Really? Wow.

Would that impact something like a DB engine then? A long time ago we used
smartscout for btrieve (or was it Pervasive SQL?), to test communications to
the engine.

If one had both, would that test work or fail? Or do the related dlls not
really care...clientless-ish?

Just curious mostly. We have a few DBs that I have up on Citrix so it's not
an issue, but the topic came up recently.

Re: Network Client Question(s)

Interesting. AND, I think you and Shaun have answered my question. So
here's another!

Can you have program failures if the app uses smb instead of ncp? Database
corruption?

Or does it matter?

Craig,

doubt if it would matter, unless the providers gave different
answerers...

Re: Network Client Question(s)

Yeah..one of my guys here said that he thinks the request gets made, the
engine handles it local to itself....meaning, beyond the original request,
the communication is largely between the engines and the server's own file
system.

Sounded right to me.

Thanks brutha

Re: Network Client Question(s)

In this case they would be.

The server's NCP name is most likely resolvable via DNS.

This allows the MS Client to believe its a Windows Box and the Novell
Client to believe it's a NCP box.

That is why it's generally best to try and ensure only one provider can
resolve the box.

Re: Network Client Question(s)

Thanks Craig.

So, given your druthers, you would rather run apps over SMB/CIFS (if they
used a client prior), than to have both clients potentially accessing the
same server?

Sounds like what you're saying.

By default the other way round.

It's the "Network Provider Order" in Windows' Network Connections'
Advanced Settings.

The "Network Provider Order" in Windows' Network Connections' Advanced
Settings determines the order.

If the server responds correctly with a TCP Reset or ICMP Destination
unreachable (Port unreachable) the Operating System will immediately try
the next client (determined by the Network Provider Order). Otherwise it
can take a long time. For all the details have a look at

Re: Network Client Question(s)

Normally you have a strong preference on which protocol to use.

Perhaps NCP to an OES server and SMB to a Windows Server.

If the MS Client cannot resolve the OES server, normally via DNS, then
it will use SMB.

The OES server will be found via SLP, not DNS, so will only be used by
the Novell Client.

That is not to say the OES server cannot be in DNS, I just would not
match the DNS name with the NCP name. This way when you are making
calls such as \\NCP_SERVERNAME\VOL\Dir, it will only resolve over SLP
and the MS Client will not get involved at all.
