Excel file is locked for editing by ' '.

Hi

I have a user Windows XP workstation with office XP
connected to an SBS 2000 server. The user has a share on
the server where he keeps his excel document. The user
opens his excel document by selecting it from the recent
document list. No other user is opening this document and
his machine is not crashing out.

But, sometimes the user will recieve the error message:

"stocks1.xls is locked for editing by ' '. Open 'Read-
Only' or, click 'Notify' to open read-only and receive
notification when the document is no longer in use.

Microsoft have said that this could be an SMB signing issue, I have tried to follow the microsoft steps for resolving
this problem. All the security patches for both XP and
Office have been installed and I have edited the register
with the changes suggested. But the problem keeps re-
occuring. Am stuck for ideas.

Thanks in advance

Can you post a link to the repair instructions you've already tried that failed to work? It would save offering you suggestions that didn't work.
