RE: RWW Disconnecting

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}

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.

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

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.

d. On the Performance tab:

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

f. Identity tab:

Predefined: Network Service.

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

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

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.

===========

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?

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

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

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

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.

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."

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.
