Hi,

As we know, the 1000 error is not a specific error. It is recorded when the
profile could not be unloaded. However, the cause may be vary. I am not
sure what steps you have done to solve the issue. So, I would like to
provide the general troubleshooting steps on this issue. Thank you for your
time.

1. Verify that you have installed Windows 2000 SP4 and IE6 SP1 on the
Terminal Server.

Windows 2000 SP4:

Internet Explorer 6 SP1
http://www.microsoft.com/windows/ie/downloads/critical/ie6sp1/default.asp

2. This issue can occur if the share that contains your user profile is not
set to Full Control. To resolve this issue, put user profiles for clients
running Windows 2000 on servers and domain controllers running Windows 2000
Server or change the permissions on the share to Full Control. For more
information, please refer to the following article.

3.  This problem occurs if the following conditions are true:
         
- You are use a Windows 2000-based computer to connect to a Windows
 2000-based Terminal Server.

- Your Windows 2000-based Terminal Server runs Citrix MetaFrame version
 1.8, which is configured in a load-balanced server farm.

- Your Windows 2000-based Terminal Server uses an antivirus program or
 a backup program that is not compatible with the Citrix software. For
 example, this is a known problem with Symantec Norton AntiVirus
 Corporate Edition version 7.5.

To work around this problem, disable or remove the antivirus program or the
backup program.

Contact the manufacturer of your antivirus program or your backup program
for more information about how to resolve this problem. There may be an
update for your software that resolves this problem. For more information,
please refer to the following article.

4. This issue may occur if Microsoft Windows or third-party programs such
as printer drivers or virus scanners do not stop and release resources when
you log off your computer. To resolve this issue, use the Microsoft User
Profile Hive Cleanup Service (UPHClean). UPHClean monitors the computer
while Windows is unloading user profiles and forces resources that are open
to close. Therefore, the computer can unload and reconcile user profiles.

To download and install UPHClean, visit the following Microsoft Web site:

5. Install the following hotfix:

Intermittent

I wanted to let you know that hotfixes are generally available for specific
issues in the Product. Please keep in mind that they are not fully
regression tested and should be applied only to systems experiencing the
specific problem. For this reason, the first step would be to verify if you
are indeed running into the problem addressed in a specific hotfix. The
individual sending of hotfixes must be tracked by Microsoft for reasons
such as: you may run into problems after installing the fix, when future
updates to the hotfix occur we want to be able to notify you. For these
reasons and others, many hotfixes are only available to customers if they
call into the appropriate Microsoft Support phone line, and receive direct
help and advice from a Microsoft support professional. We are not equipped
to send out and track hotfixes here in the Newsgroups forum.

One option is to contact Microsoft Product Support Services directly to
obtain the fix. For a complete list of Microsoft Product Support Services
phone numbers and information about support costs, visit the following
Microsoft Web site:

http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

NOTE: In special cases, charges that are ordinarily incurred for support
calls may be canceled if a Microsoft Support Professional determines that a
specific update will resolve your problem. The typical support costs will
apply to additional support questions and issues that do not qualify for
the specific update in question.
