Re: Client performance problem windows 2003 server...

Hello,

Thanks for your response.

First, I would like give a summary of this issue including setup
environment, main issue you encountered and the actions we have performed.

Setup environment:
============
A Windows 2000 server was at first installed in site A (both geographically
and in the site configuration) this is acting as the "primary" domain
controller.
This server is GC, DDNS, DHCP, WINS, Print and file server.

Then at site B there is a windows 2003 server. This is acting as a GC,
DDNS,
WINS, file and print server.

The sites are connected through a VPN tunnel with cisco pix firewalls. The
internet connection is at site A a dedicated connection and at site B a
ADSL 1Mbit connection.

Issue:
==============
When the connection between the two sites is terminated, the clients at
site B becomes extremely slow to logon and even to access the local server
at site B.

Actions:
====================
1. Yes every client in Site B is suffering from this
2. The DNS is replicated through sites and services
3. The DNS settings on site B is distributed the following way to the
clients: (the DHCP scope settings)
Primary dns: site Bs win2k3 server
Secondary dns: site As win2k server
Same setup for wins...
4. The mappings on the clients are mapped like this:
NET USE G: \\smedjan.local\DFSroot\Verktyg_Gemensam /PERSISTENT:NO
If change it to NET USE G: \\verktyg\Verktyg_Gemensam$ /PERSISTENT:NO
then the problem with slow connections disappears.
\\smedjan.local is the domain name and verktyg is the file server's name.
a, the file server is Server B in site B
b, If don't map the shares there is no problem

5. If change the group policy setting on the w2k3 server at site B the
policy won't be applied to the clients until the w2k server at site A has
that group policy information. Even if run GPUPDATE on the clients and
server.
If make a change in the policies on w2k server at site A the clients gets
that policy applied directly with GPUPDATE.

Now from the above conclusion, we can find the issue should have two
aspects:

1. It seems that Site B's clients cannot authenticate by Win2k3 server. It
may be caused by DNS replication.
2. It may be caused by the mappings and it looks like a DFSroot issue

Therefore, we can perform the following steps to isolate the issue:
1. Terminate the connection between site A and B
2. Boot one client computer by using safe mode with network
3. Don't map the shares and check if the slow logon issue still persists on
this client.
4. How long will it take in logging on?
This test will help us isolate if the issue is caused by replication
between A and B or by DFSroot.

The issue is complex and Network MPSReport and Userenv log on files are
very important for us to perform further research on it.

I don't know why I haven't received your E-mail last time. Would you
please use two different E-mail accounts to send the information I
requested to me at v-amanwa@xxxxxxxxxxxxx? You effort on this issue would
be appreciated and I'm looking forward to hearing from you.

Thanks & Regards
