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:

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.
