1061.0. "PPP / DECSERVER problem?" by FOUNDR::TOMASWICK (Joe - Enterprise Systems Engineering) Thu May 08 1997 01:47

	Is anyone aware of any problems running Exchange
via a PPP connection on a DECSERVER? Exchange hangs when
I try to run it over that connection. Netscape, TELNET,
& long file trasfers all work ok. Just Exchange hangs.
Anyone else tried to run it via PPP? Any setup tips?

Thanks,
Joe

1061.1Some things to try...DYPSS1::YINGLINGDave (N8UTX), NSIS, Dayton, OH USAThu May 08 1997 12:4033
Joe,

1.  I using a PPP on a DECSERVER and having no problem.  The only hint/kink 
that helped me was to make sure that the DNS and WINS IP addresses were set in 
the Dial-Up Networking connection icon rather than the Control 
Panel->Networking route.  The Exchange client requires both WINS and DNS to 
work properly.  Do you have WINS and DNS IP addresses assigned?

2. Assuming you are using Windows 95, a good reference for setting up 
your PC is:

	http://www-ccs.wro.dec.com/nt/RemoteAccess/W95Client.html

The above article will lead you through the setup.  If you have the Dial-Up 
Scripting tool or the ISDN Accellerator installed, I have written a script
that automates the dialog between dialing up and sending "C PPP" for a
DECSERVER.  If you would like a copy, let me know. 

3. I'm assuming from your symptom description (hang) that you are never 
getting an initial connection to your mailbox.  Again, WINS and DNS are 
usually the culprits, but you could also be having a domain controller 
connectivity problem caused by an improper setup/configuration.  If you 
modify your profile to NOT Use Network Security, you can sometimes get past 
that problem.  Assuming Windows 95, right click on the Inbox icon on the 
desktop and select Properties.  The default profile properties will be 
shown.  Microsoft Exchange Server should be highlighted, click on 
Properties.  When the Exchange Server properties window shows, click on the 
Advanced tab.  De-select Use Network Security During Logon.

Regards,

Dave

1061.2Keep Trying - PPP can work better than RASMK1BT1::BLAISDELLThu May 08 1997 15:4214
    .1 is a good description of the most common problems. I just want to
    add that for myself I find that DECserver 700 PPP connections are far
    more reliable and troublefree than RAS connections. CCS has been unable
    to find any problems with my RAS setup; but two out of every three times
    I try RAS my system hangs and has to be rebooted. This never happens
    with the PPP connections. And I know I'm not the only one with this
    problem. So keep working on your PPP connections. 

    Does anyone know how to get a list of all 28.8 and faster PPP numbers,
    simliar to the CCS posting of RAS numbers? If it wasn't for the busy
    signals I get on the DECservers I would probably never try RASing in
    again.

    - Bob
1061.3PYRO::RONRon S. van ZuylenThu May 08 1997 18:5317
    I never have problems with RAS (which, I remind you, is PPP) or DECserver
    700 PPP with either Windows 95 or Windows NT Workstation.  (Using
    different PCs.)  I never get dropped unless I disconnect myself and my
    systems never "hang".  I do, however, get better performance from RAS
    since it supports software based compression (which is more efficient
    than the modem compression and doesn't tax serial ports on either side).
    
    If your PC is hanging, I'd seriously doubt there is something wrong
    with the RAS dial-ins.  With symtoms like you're having, it wouldn't be
    easy to find a problem with your RAS setup.  A misconfigured dialog box
    won't cause your PC to hang.  :-)  It could be hardware... it could be
    software... happy hunting.
    
    As we're moving toward RAS and moving away from DECservers for internal
    dial-ins, you'll need to get this working some day.

1061.4Windows Password Required?MK1BT1::BLAISDELLTue May 13 1997 14:1213
    Of course I reported the problem in .2 to CCS but I've also continued
    to try different things myself while waiting for more help. The problem
    is getting better.

    I've never used a windows password on my home system and I'd been told
    one was not necessary for RAS logon. In theory maybe not; but, I've
    added a password and RAS logons are now succeeding regularly. 

    Note that DECserver 700 dial-ins with network logon do not require the
    windows password for reliable logons, but RAS logons do. Does anyone
    have an explanation for the different behavior?

1061.5domain login/resource locationPARZVL::matrix.ogo.dec.com::kennedynuncam non paratusTue May 13 1997 15:5610
PPP just supplies you with a TCP/IP stack, I believe
that RAS also logs you in as a member of your Digitalx
domain.

Is it possible that the hangs you get with RAS are 
because your system is trying to locate/connect to
some NT domain resources (e.g. network drives, remote 
printers)?  That's something that might not happen
when using PPP.  I've found that some of the MS
networking does take over the machine.  
1061.6No remote disk and printer connectionsMK1BT1::BLAISDELLTue May 13 1997 19:1715
    re .5

    "Is it possible that the hangs you get with RAS are  because your system
    is trying to locate/connect to some NT domain resources (e.g. network
    drives, remote  printers)? "

    No, I do not make any such automatic resource connections. The process
    and set-up for DECserver and RAS dial-ins are indentical except that
    with a DECserver line I bring up a terminal window after connection to
    enter the lat password and issue the CONNECT PPP command. Both 
    DECserver 700 and RAS numbers are set to auto login to the Digital1 NT
    domain.

1061.7Decserver setup?FOUNDR::TOMASWICKJoe - Enterprise Systems EngineeringThu May 15 1997 18:489
	I am still having problems. Can someone post the results
of a show port, sho port ppp ipcp, & a show port ppp lcp from a 
DECserver that works with PPP & exchange?

Thanks,
Joe


1061.8PYRO::RONRon S. van ZuylenFri May 16 1997 00:5750
    If PPP is working correctly, all Winsock TCP/IP applications should
    work... including Exchange.  Anyway, here is a dump locally... where
    it has always worked.  Nothing special.

1061.9Try the .pwl fileNQOS01::16.81.32.132::ATKINS[email protected]Mon May 19 1997 04:1111
Although I never assoicated this with PPP connections I did have a problem 
with the Exchange client that caused my system to hang. The cure was to delete 
the c:\windows\<userid>.pwl file. This will cause you to re-enter your 
password but just about everytime I have a strange Exchange problem this cures 
it.

There are a couple of Technet articals on problems that a corrupt password 
file will cause.

Steve
1061.10CRC errors will definitely hang MS-ExchangePTOSS1::BREZLERFri May 23 1997 22:4621
    I am a telecommuter and dial in daily to a DECserver700
    (BL10-40...whatever that means..). Until about three months ago I was
    running W95 on a Celebris GL5133. I was getting Exchange hangups but
    had no idea why. I moved to WNT about three months ago and again
    started to see hangups on Exchange. One of the tools in the WNT bag is
    the Dial-Up Networking Monitor. It gives you the ability to see a
    variety of device errors if they occur. I noticed that when I got a CRC
    error while using Exchange, it would freeze. The only way to get it to
    come back was to hangup and redial, or use Ctrl-Alt-Del and end the
    Exchange task and restart it. With a 5 minute Exchage start up this
    became a pain in the ******. So I have played with tracking the ports
    on the DECserver that give me the most CRC errors and keep trying
    during the day to use one that is less error prone. I also use my ISP
    when the errors get so bad I want to pull my hair out. There errors
    have little-to-no effect on my use of Netscape and KEA (my terminal
    emulator). I wish I could find some setting that would eliminate this
    problem but for the time being I'm living with it. It certainly
    contributes to a non-productive environment. CCS has not been able to
    help......
    
    Any input would be welcome.....
1061.11RAS vs DECserver vs file share access problemZEKE::BLAISDELLWed Jun 04 1997 20:4814
    Yesterday morning I dialed in from home to check mail. I store my
    personal address book and personal folders on an NT file share.

    I dialed into one RAS service, invoked exchange and my system froze up.
    So I rebooted, dialed a different RAS number and again my system froze
    up. The third time I dialed into a DECserver, connected PPP and invoked
    Exchange. I was notified that my personal address book could not be
    accessed and asked if I wanted to proceed. Said yes and I proceeded to
    read new mail.

    Why the different behaviour using the DECserver?

perhaps you couldn't get to the address book because
you hadn't logged into the domain (which I think gets
done automatically when you use RAS).

    Are you suggesting that there were also problems with the Exchange
    server for the first two connect attempts? Maybe I'm giving the
    infrastructure too much "credit" and it is even more fragile than than I
    thought. On the DECserver dial-in I was obviously able to reach the
    Exchange server and I am assuming there never was a problem with it.
    And, regardless of the problem, my PC locked up and that's a problem
    regardless.

    The DECserver dial-in is also set to automatically log into the NT 
    domain. In normal operation I see no difference between DECserver and
    RAS dial-ins except a short stop at the lat prompt to issue the connect
    PPP command.

1061.16HELIX::SONTAKKEWed Jun 04 1997 22:304
However, lately I am noticing that the PC-clock synchronization is noo longer
done when you comein via DECserver dial-in on the ZK3 boxes.

    	Yeah, I changed to DNS/WINS last week and was getting an NT logon
    	script when I connected via RAS [and would reconnect two network
    	drives ... one for .PST/.PAB files and the other for my area on
    	the NT server] but I haven't seen that all week.  But the drives
    	do get reconnected.

1061.18DNS/WINSPYRO::RONRon S. van ZuylenThu Jun 05 1997 00:257
    Remember, RAS sets your primary/secondary DNS and WINS automatically...
    you don't set anything.  DECserver PPP doesn't... and you need to specify
    them in the properties for the specific dial-out.  (DECserver PPP also
    doesn't support the advanced software based compression that RAS has...
    but that is behind the scenes stuff.)

1061.19What's working and what's not ???PTOSS1::BREZLERThu Jun 05 1997 00:539
    So are we saying that we do get the MS-Exchange client lockup on
    dialing in thru DS700's and we don't using RAS? Is anyone using RAS
    experiencing this lockup symptom? Is anyone using dial-up thru DS700's
    getting a rock solid MS-Exchange client performance with no lock-up's?
    
    Can we get some stats from the dial-up user community?

    My note describes the opposite behaviour. On the DECserver connection I
    am gracefully told that the file share is not available (that my PAB
    cannot be accessed) and then I can proceeed to use the exchange server.
    On the RAS connection, Exchange appears to take over my PC and I have
    to reboot.

    I wouldn't know about this but are you implying that RAS performance
    should be better than DECserver 700 connections? Is this theory or fact?
    It is certainly not my experience. What other factors affect relative
    performance?
