Re: RWW Disconnecting

Brandy,

Sorry I haven't responded for a few days. I have been away from the office
and on vacation for a couple of days.

A funny thing happened over the weekend. The disconnecting issue seems to
have repaired itself. I have been connected from a remote site for about 3
hours now. I did notice that after running CIECW last week before I left,
the DHCP service on my SBS server shutdown (My Internet router is a
multifunction device - firewall, DHCP server and even a wireless access
point device. I do use these functions for a few others that I have given
the key codes to for Internet access. Shutting off the DHCP service would
also disable the firewall and other functions of the router like the
wireless access. I would like to keep these functions available for use and
not put the router into a "pass-through" state because I only have one NIC
in the SBS server and the firewall on the server is disabled.) Now my
clients are back to using the router for DHCP but using the SBS server as
their sole DNS server. This seems to have put an end to the "disconnecting"
issue. If this does not present other problems I will let it be for now.

Thank you for all your suggestions and comments. I will continue to monitor
my situation to see if there is a "relapse" of the problem. Thanks again
everyone.

Tony

Hello Tony,

Thank you for posting back!

I have read through the icwlog.txt, it seems that you have correctly run
the CEICW.

To capture screen shot, please see:

a. When the screen appears, press the Print Screen key several times,
which
is to the right of the F12 key on the keyboard.

b. Open Paint or Microsoft Word or WordPad.

c. Click Edit (menu) -> Paste or press Ctrl + V.

d. Click File (menu) -> Save. Save it to a file and attach it in email to
send it to me.

By the way, please help me to gather following information for further
research:

1. When the issue occurs, can you internal clients access the Internet web
sites by IP address? For example, access 66.249.89.99 and 207.46.20.60.

2. Please take your time to change another router and the NIC on your SBS
Server to test the issue. These steps are very important for us to isolate
your issue. Please rerun CEICW afterwards.

Please take your time to gather the information. If you have any updates,
please feel free to let me know. I am looking forward to hearing from you!

Best regards,

Brandy Nee

Hello Tony,

Thank you for posting to the SBS Newsgroup.

I understand that remote client encounts following error message when
RWW
-> RDP to the domain computer desktops:

VBScript: Remote Desktop Disconnected
An internal error has occurred.

If I have misunderstood your issue, please let me know.

===========

Based on my research, error message "internal error has occurred"
indicates
this is a Network Issue. I suggest that you perform my suggestions first
to
see how it goes. If the issue persists, please help me to gather more
information for further research. Thanks a lot for you co-operation!

I assume that your Network topology is:

{Remote Client} {Internet} {Router} {NIC} {SBS 2K3 + Domain client
workstations}

Pretty close:

{Remote Client} {Router} {Internet} {Router} {Switch} {SBS 2K3 + Domain
Client Workstations}


Suggestion 1:

I strongly suggest that we rerun the Configure E-mail and Internet
Connection Wizard to make sure your Network settings is correct. Please
strictly follow KB825763 for more detail steps:

[NOTE]: Please go to the c:\program files\microsoft windows small
business
server\support folder, rename the icwlog.txt file to icwlog.old. after
you
rerun CEICW, it will generate a new icwlog.txt.

825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763

Please follow KB309633 to make sure that you have correctly configured
your
SBS Single NIC:

309633 How to Configure a SBS for Full Time Internet Access with a
Single
Network Adapter
http://support.microsoft.com/?id=309633

I followed both KB exactly.


Suggestion 2:

Please check if the DefaultAppPool had some non-standard settings. To do
so:

a. Expand to Internet Information Services\Yourdomain (Local
Computer)\Application Pools\DefaultAppPool.
b. Right click DefaultAppPool and select Properties.
c. On the Recycling tab:

Check the box "Recycle worker processes at the following times". By
default
it is 04:00.

No changes were neccessary.


d. On the Performance tab:

Check the boxes under: "Idle timeout" (600) and "Request queue limit"
(4000).

I had to change the "Request queue limit" from (1000) to (4000).


e. Health tab:

Enable pinging. Ping worker process every (frequency in seconds): 30.
Enable rapid - fail protection. Failures: 5. Time Period (time in
minutes):
5.
Startup time limit: 90
Shutdown time limit: 90.

No changes neccessary.


f. Identity tab:

Predefined: Network Service.

No changes neccessary.


g. If you make any changes, please run "iisreset" (without quotation
marks)
to apply these settings.

Did this.


Suggestion 3:

If you run a backup program or antivirus scan while remote users are
connected to the network, Remote Web Workplace remote desktop sessions
may
be disconnected. If this occurs, the error message "An Internal Error
has
occurred" appears, and users are returned to the Remote Web Workplace
computer selection page or log on page. At this point, users can log
back
on to the remote computer and resume work.

If this is the case, you may want to call PSS to obtain the hotfix
821438:

821438 FIX: Antivirus Programs May Cause Some Web Applications to
Restart
Unexpectedly
http://support.microsoft.com/?id=821438

I do not have either of these running during normal business hours.


Suggestion 4:

Based on my research, I noticed that we have received some similar
issues
caused by the hardware. So please check your router and the SBS NIC. I
suggest that you change another router and SBS NIC and test the issue
again.

I do not have another router currently to test with, but will try and get
one. I'm not sure it is a router issue because the VPN I have set up for
our VoIP system does not go down during these "outages".


===========

If the issue persists, please help me to gather following information
for
further research:

1. When did the issue occur? Did you experience this issue before? If
no,
did you make any changes on the SBS Server or Network recently?

I started noticing the "outages" in our internet connectivity when I first
introduced the SBS server into our network. I changed all internal
clients
to use the SBS server for DHCP and DNS exclusively removing the Internet
Router from their setup. It then became very apparent when we started to
use RWW and the remote clients were being disconnected.


2. Does this issue occur to all remote clients or only certain clients?

Yes, all clients no matter the OS.


3. If you ask the problematic client to log on another remote computer,
will this issue occur?

Yes, it does not matter which client they log into, when it happens they
are
booted right off of the system. I know that this sounds like a router
issue
but as I mentioned above, the VPN I created using the DSL connection does
not go down during these times. Also, from a remote client, the user can
ping the Internet router at our office but cannot connect to the SBS
server.
Internal clients cannot get out to the Internet during these "outages",
unless I change the DNS server they use to the Internet router and remove
the SBS server as their DNS server (I don't ususally like to do this
because
it will clear before I can visit all of our internal workstations).
Again,
as mentioned earlier, after a 5-6 minute wait the problem seems to reset
itself.


4. Just to double confirm, will this issue occur in LAN?

If the internal client accesses the RWW using
https://server_name.domain.name/remote it does not appear to happen. If
they use https://public_static_IP_address/remote it will occur.


5. Please help me to gather the icwlog.txt: c:\program files\microsoft
windows small business server\support. You can send the log file to my
mailbox.

I will send you a copy of this file to your mail box.


6. Also, on the remote problematic client workstation, open IE -> Tools
->
Internet Options -> Advanced tab. Uncheck the box "Show Friendly HTTP
errors messages". Close IE and open IE again. Reproduce the issues and
please help me to gather following screen shots for accurate research:

a. "VBScript: Remote Desktop Disconnected. An internal error has
occurred."
b. "For the "Main Menu" then displays the standard "Page cannot be
displayed" message in IE".
c. "RWW will continue giving the user "The page cannot be displayed"
message for about 5-6 minutes."

Forgive my lapse in memory. How exactly do I make the screen images to
send
to you?


Please take your time to perform my steps and gather the information for
further research. I am looking forward to hearing from you!

Best regards,

Brandy Nee

Hello everyone,



I know that this is a long post, but I am beginning to get desperate to
find
an answer. I tried finding a solution to this problem a while back but
no
luck so far. Following is my setup.

SBS 2003 standard with SP1
Sharepoint Services with SP2 update

Workstations are XP Pro with SP2
- IE v6 with the pop-up blocker disabled

The exact problem I am having is this:

A user (from the internet) connects to RWW and logs in. The user (or
administrator) then chooses to "Connect to Client Desktops". The user
again
logs in and begins working as if they were sitting at their desk. After
a
random period of time (my results have shown anywhere from 10 minutes to
nearly an hour) the user is disconnected and the following message is
displayed.

VBScript: Remote Desktop Disconnected

An internal error has occurred.

This message appears in a dialog box with an "OK" button to click on.
Clicking on the "OK" button or the link for the "Main Menu" then
displays
the standard "Page cannot be displayed" message in IE. Shutting down
the
browser and then restarting it and attempting to reconnect to the LAN
using
RWW will continue giving the user "The page cannot be displayed" message
for
about 5-6 minutes. After this time the user can now reconnect to the
RWW
and reconnect back to their desktop where they will find it in the exact
same state that they left it in. Again after a random amount of time
they
will again be disconnected and blocked completely from the RWW only to
start
the whole cycle again.

Here are a few of the previous suggestions I have tried.



1) Installing security update MS05-019 or Windows Server 2003
Service
Pack 1 may cause network connectivity between clients and servers to
fail:
http://support.microsoft.com/kb/898060/ - I have applied the patch
from
this KB with no change in the issue.



2) 159211 Diagnoses and Treatment of Black Hole Routers
http://support.microsoft.com/?id=159211 - I also looked at this as a
possible explanation to this issue.



3) "Try different screen resolutions on the client end (i.e. try and
match the screen size at both ends). Try a different selection when you
log
onto RWW, such as 'modem 28.8' instead of anything faster." - I tried
this
suggestion as well with no change.



Following is the results from ipconfig /all from the SBS server:

When these "disconnects" happen for the remote workers I have also
noticed
that our internal users cannot get out to the Internet. I know that our
Internet connection is not going down because I can access the router
and
ping out to other locations on the Internet. We also have a VPN
connection
that comes in over the DSL link that is physically separate from our SBS
server (Cisco PIX on both ends to create the VPN tunnel). This
connection
does not go down and is physically separate from our SBS network. In
fact,
when the "outage" occurs I cannot even access the Internet from the
server
itself.



This last piece of information leads me to believe that it has something
to
do with DNS on the SBS server itself. All of my clients point to the
SBS
server as their only DNS server. When I change a computers DNS server
to
the router (as in during one of our "outages") there is no problem
accessing
the Internet. I've tried looking at the event logs but have found
nothing.
I even looked at the logs on our Internet Router but again found
nothing.



I do not know what else to try at this moment. I really need to get
this
to
stop disconnecting remote users at random because I have a few end users
that will only be connecting remotely and do not have time to keep
re-connecting. If anyone has any thoughts or suggestions I am all ears.
Thank you in advance for your help.



Tony



P.S. If you need any further information I will gladly provide what I
can.
