Issue:
An error screen while try
to edit Office 2007 documents uploaded in SharePoint Document library
Unknown Error Trying To Lock File
This is mostly related to
operating system and already been fixed in SP1, though sometimes we have to
modify below registry settings.
Resolution:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters
On the Edit menu, point to
New, and then click Multi-String Value.
Type AuthForwardServerList, and then press ENTER.
On the Edit menu, click
Modify.
In the Value date box,
type the URL of the server that hosts the Web share, and then click OK.
Exit Registry Editor.
