Hi
our laptops hang when accidentally accessing our domain-dfsroot when
connected other networks. This typically happens when the laptop has been put
into standby when taking it from the domain-network to to the other network.
It does not happen when the laptop has been shutdown and rebooted when
connecting to the other network. But then, after having had a connection to
the domain-network with VPN over this other network, it happens again.
thanks for any suggestions

Open Device Manager, open the properties on your ethernet card, or
wireless device and, if you're lucky, you'll have a Power tab. Deselect
"Allow the computer to turn off this device to save power".

You can do the same thing with a USB device by disabling the power
saving feature of all "USB Root Hub" entries.

Thanks for your reply I have tested it but the problem remains. I think it
has nothing to do with powermanagement, but the DFS client (Windows 7 has the
same problem as XP) keeps on trying to reach the complete list of domain-dfs
servers.

The DFS Client should stop trying as soon as the IP connection has changed
the DNS suffix.

Hi,

DFS does not detect the network state change when removed off the original
network. Nor does DFS note the network state change when added onto a new
network. When Explorer is opened DFS will try to resolve the path to this
mapped drive but it is not reachable. DFS will not gracefully fail out and
explorer appears to hang.

The command line solution is to run "dfsutil /pktflush" once the machine is
undocked/removed from network.

Hope it helps.

thanks for your reply
But alas, even after dfsutil /pktflush the problem persists
The output of dfsutil /pktinfo remains the same before and after /pktflush:
a list of servers involved in the dfs.
It looks like /pktflush does not do what it pretends.

Hopefully you have alternatives, for this is indeed the right direction for
a solution in my opinion
thanks again,

Hi Michiel,

Thank you for your update.

Technically, the issue should be resolved after taking dfsutil /pktflush.
Given the current situation, could you please help me confirm the result? I
list a detail information below:

a. install Windows Server 2003 Service Pack 1 Support Tools on Windows XP
and run the following command to flush DFS cache:

Download: Windows Server 2003 Service Pack 1 Support Tools
http://support.microsoft.com/kb/892777

b. please run the following command line on the client to display the
cached target referrals and active target.

Dfsutil /pktinfo

If possible, please post back the result here.

c. Then manually clear the referral cache by using Dfsutil.exe with the
/pktflush parameter.

Dfsutil /pktflush

Also, please post the result here.

d. Then, please run Dfsutil /pktinfo again to display the new cached target
referrals and active target. And post the result here.

For more information about DFSUTIL, please see the following document.

Thanks.

thanks for your reply!
I issued the commands when connected to the other network
It seem as though dfsutil /pktflush doesn't do what it pretends in our
situation
looking forward to your next reply!
thanks again

Hi Michiel,

Thank you for your detail information.

According to the information you provided, I have the following
conjectures:

Scenario 1: These commands are run in same location. The first command
should be run in original network, the second and third command should be
run in new network.
Scenario 2: The original network and new network belongs to a same site.
The computer in different network environment has different IP address and
subnet. There is a communication error in new location.
Scenario 3: The DFSUTIL /PKTFLUSH command doesn¡¯t work.

Based on current situation, I suggest we capture network packets to narrow
down the problem. Thank you for your cooperation.

1. Please run the following commands on computer in original network:

Dfsutil /pktinfo
Ipconfig /all

2. Enable netmon to capture network packets on the computer.

1) Download NetMon3.2 from the following website and install it on the
computer
http://www.microsoft.com/downloads/d...0af-1e08-4a21-
a26b-ec2f4dc4190d&DisplayLang=en
2) Launch NetMon3.2.
3) In the Microsoft Network Monitor 3.2 window, click Create a new capture
tab ¡*
4) In the new tab, select all the Network Adapters in the Select Networks
window.
5) After that, press F10 to start NetMon.
6) Try to access domain-dfsroot on the computer.
7) Go back to the NetMon window and press F11 to stop the NetMon.
8) Press Ctrl+S to save the Netmon file named original.

3. Then, please put the computer into standby, take it to the other network.
4. Please run the following commands on computer in new network:

Ipconfig /all
Dfsutil / pktflush
Dfsutil /pktinfo

5. Please take step 2 to capture new network packets, and save it named new.
6. Please use Windows Live SkyDrive (http://www.skydrive.live.com/) to
upload the files (original and new) and then give me the download address.
7. Please post every result for command above.

Thank you for your cooperation.

Hope it helps.

Robinson
I did all the testing and put the results here
http://cid-a03ee8e9ffc88ef5.skydrive...x/.Public?uc=1

A few remarks:
- running dfsutil /pktflush Before or After the switch to the other network
doesn''t make a difference
- after having accessed the dfs-root pktInfo gives a whole lot more
information which is indeed being flushed after dfsutil /pktFlush, so
pktFlush does seem to do what it pretends. But unfortunately not as much as I
would like
- the 2 networks have no connection whatsoever
- I see in the Netmon Capture of the problem what I expected: Tha laptop
tries to access the dfs-servers in a roundrobin

I am very curious about your reaction!!!
thanks again

Hi Michiel,

Thank you for uploading these files. I did check on them and agree with
you, this issue is weird.

"DFSUTIL /PKTFLUSH" seems work partly. I suspect the issue could cause by
following factors. Could you please help me check them?

1. A security/network software (such as antivirus or accelerator)holds this
setting.
2. A third party software holds this setting.

Could you please take a clean boot to test this issue? I suggest you
temporarily remove antivirus to test the issue if possible.

Clean Boot
========
1. Click Start, type "MSCONFIG" (without the quotations) in the Search Bar
and Press "Enter" to start the System Configuration Utility.
2. Click the "Services" tab, check the "Hide All Microsoft Services" box
and click "Disable All" (if it is not gray).
3. Click the "Startup" tab, click "Disable All" and click "OK".
4. Restart the computer and test the issue.

Also, please close all open windows before putting into standby.

If the issue still persists, please feel free to let me know. I will
involve my colleague work on the problem.

Thanks.

Robinson
thanks again for your help

Unfortunately the problem persists
Even when disabling all non-microsoft services and all startup-items

I have a feeling that this is what we call a 'hidden feature'
In other words 'By design'
But I cannot believe that we are the only ones in the world that run into it

Cheers
Michiel

Hi Michiel,

Just let you know that I am still working on it. Thank you for your
patience.

Best regards,

Hi Michiel,

After discussing with my colleagues, we have to confirm following points:

1. Does the issue only occur on one computer or some computers? If all
computer has same issue, we need focus on the issue on server side.
2. Please try to run following command in new network:

DFSUtil /SPCFlush

Does it work?

3. If the issue still persists, could you please collect more information
to troubleshoot the problem?

Collect MPS Report
=====================
1. Download proper MPS Report tool from the website below.
