Logon Error: "command length incorrect" (NO ONE CAN LOGON)

[Griobhtha]

I've seen another post somewhere and someone else had this problem,
but I haven't found a solution. We're using WXP Pro, SP2.

After doing a repair install (the other person just had it after using
Windows Update), at logon, after entering the correct, AND VALID,
password either for a user Or the Administrator, Windows Logon
displays the following Logon Message in a box:


"! 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 administrator."


No matter how many times logon is attempted, or with what account, the
message continues to be issued. Thus, NO ONE can logon to the GUI.

The Recovery Console can be used to logon as Administrator, but no
password is requested even though there is one in place. I've
searched the MSKB but didn't find any reference. Implementing "Last
known good configuration" does not fix the problem.

I am at a total loss and pulling my hair out. Please help.

Thanks,
Griobhtha

(snip multipost)

Please don't multipost. Crosspost only judiciously if you must. I've
already given you an answer in the other newsgroup to which you posted.
Search for your name there.

Here is a link explaining why multiposting is Evil.

This error can occur if you have a hard drive volume name that is more
than eleven characters in length. To circumvent this issue, please rename
such volumes so that they consist of eleven characters or less.
