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.
