DFS-Slow performance first time

Hi,

We are using DFS on a Windows 2000 Server for homedirs.
The server is a memberserver in a Windows NT4 resource domain.
CLients are Windows 2000 machines.

The first time a client tries to browse the DFS share it is very slow, about 10-30 seconds just to open a share with 3 subfolders.
Seems even slower when saving a document and trying to browse to the right location in the save dialog.

If the client close the explorer window and try the same thing immeidately, it works as expeted, e.g. immidiate response!

Seems like it is ok for a while after this and then the slow response time reappears.

Tried to put the dfs server in lmhosts #pre to see if WINS was causing this, but it didn´t make any difference.
Removed all other server mappings, no difference.
Installed SP4 to a client and added the key HKLM\System\CurrentControlset\Services\Dfs\Parameters:
DfsDisableSiteAwareness =1 as described in KB:810418, no difference.

Does anyone know why the clients are behaving like this with the DFS share?

First of all: this registry is for DFS server machine. You need to put SP4
on DFS Server machine and add registry key on that machine as directed in KB
article (and then reboot).
Can you take network sniff of access (on the client machine) which is taking
10-30 seconds to finish? Looking at sniff we will see what packet exchange
is taking long time here.

Ok, Since I received som many suggestions on this problem ;-)

The resolution is in the in KB Article:810418 but for MS I can assure you that it is NOT 5 seconds, more likely 10-15 seconds delay.
This registry key should be applied to the DFS server not the clients....

After we made this modification the "first time delay" for browsing DFS folders is gone.
 
Nice to hear to your problem is solved.
