Hi all,

I have installed Windows Server 2003 SP2 on my R2 server. Now when I try
and browse the shares of the server from Windows Vista (I have two installs
of Vista) it is very slow to resolve folder names. For example I have a
drive mapped to a share, when I click the arrow next to the drive it takes
about 10 seconds to resolve the list of folder names within the share.
This delay is happening on any folder I try to open inside any share. If I
access the server using Windows XP, no problems at all. Even running a
virtual machine with XP on a Vista host has no problems.

I am reluctant to uninstall the SP2 because of security, but I am starting
to run out of options.

Here are the fault finding techniques I have tried so far;

1) Disabled NBT.
2) Changed the local Group Policy to disable all SMB signing.
3) Connected to Vista from the Server, no delay when browsing Vista from the
Server.
4) Installed Network Monitor v3 on Vista and had a look at the frames, not
much help.
5) Ran a robocopy from the Server to the Vista machine (surprise surprise,
no help).

I should mention that my laptop is not a member of the active directory
domain, but the other Vista machine is and they both have problems.

My next step will be to reinstall the SP2 on the Server, but I do not think
that the SP did not install correctly, I suspect Microsoft made a change of
some sort within the Service Pack which is causing the issue.

I have read another article in a forum about someone else having the same
issue.

Does anyone have any other ideas on how to fix this problem?

Regards.

Read a post in the Internet. Microsoft tech support confirms that slow computer browser issue. Microsoft is trying to do new way to browse network resources and move away from Netbios traffic/Master browser.

I experience the hanging "Calculating" wait when copying files from a
network share to a brand new Vista machine. I tried the various
workarounds mentioned on the internet, but the problem only resolved
itself when I removed a D-Link10/100 Fast Ethernet Switch out of the
connection. Once I remove (cheap) switch the problem went away. You
mileage may vary, but perhaps there is something in the workings of
the D-link switch that doesn't play nice with Vista (or vice versa).

Does performance improve when copying files via the command line as opposed
to Windows Explorer interface? File copies via the command line use the SMB
protocol and the redirector component while file copies through the GUI use
the redirector and the shell components.

If the file copy is also slow from the command line, please take the
following steps to do the troubleshooting:

Step 1: Check the Network Adapter
==================================================
1. Update the Network Adapter to the latest driver from the manufacturer.
NOTE: Although this is a simple step, this has fixed a large number of slow
file copy cases.
2. Go to Device Manager -> Right click on the Network Adapter -> Properties
-> Advanced, please temporarily disable TCP and IP checksum offloading.
This will cause this processing to be handled by Windows TCPIP stack
instead of the Network card.
3. Set the Network Card and Switch from Autodetect to a hard coded link
speed such as 100mb/half duplex.

Step 2: Add the CopyFileBufferedSynchronousIo registry entry
==============================================
1. Click Start, type regedit in the Start Search box, and then press
ENTER.
2. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\System

3. On the Edit menu, point to New, and then click DWORD Value.
4. Type CopyFileBufferedSynchronousIo to name the new entry, and then
press ENTER.
5. Right-click CopyFileBufferedSynchronousIo, and then click Modify.
6. In the Value data box, type 1 , and then click OK.
7. Exit Registry Editor

Step 3: Adjust the MTU settings for VPN connection:
==============================================
a. On Vista notebook, please try to ping the File Server (laptop) site with
the following command:

ping 192.168.0.7 -f -l 1472 (replace 192.168.0.7 with the IP of the File
server laptop)

Will you receive the following response?

Reply from 192.168.0.7: bytes=1472 time=74ms TTL=58

b. If you receive a negative response, please try to ping with reduced
packet size of 10 (1462), will the ping work?
c. Repeat step b using a smaller MTU size. Repeat this process to check if
the ping command will succeed.
