Windows XP Logon Error

[Panacik]

Hey everyone,

On our laptops running windows XP in a domain at work we are seeing an error occure after it installs updates from WU.

I cant see which update is causing the error and it is becoming quite frustrating.

I know it only happens to machines registered to a domain but not to ones in a workgroup.

The error is when logging on to the machine after an update where we recieve the following message:

Logon Message:

The system cannot log you on due to the following error:

The program issued a command but the command length is incorrect.

Please try again or consult your system administrator.

Well i am the admin and we are not running any scripts or anything when users log in to their machine locally, so i am baffled as to which program this is referring to.

For now, we do have a work around of choosing last known good configuration, but that means we cannot update the machines until this issue is corrected.

Thanks,

Rich

I have just found that update KB867282 on its own makes Explorer.exe crash so you cannot open anything appart from through Task Manager.

I have found a way to uninstall the KB when this happens if anyone is interested.

I still havent found the one which causes this login issue though and really could do with finding out so we can take it from our WUS server.

Thanks,

Rich

Did you ever find a solution? I've tried Safe Mode (same message), Last Known Config, and Repair install. No help

Thanks :cry:
