The reason for this can be a multitude of issues – like a dodgy codec, etc – and seems to be rather in-discriminant as to which file type it decides to screw up with (AVI, MPG, WMV, ASF, etc).

To get around this problem though, it is possible to easily disable this feature. Either fire up a command prompt or execute this straight from the run dialog box:

regsvr32 /u shmedia.dll

And if you want to re-enable it again at a later date:

regsvr32 shmedia.dll

Now, the only knock-on effect is that you’ll no longer be able to see summary information in the file properties. In my opinion though, it’s a small price to pay!!

So how do you do it? Well, the location of My Documents is stored in the registry (which is read by the explorer process when it’s spawned) and is located here:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal

As you would expect, editing this one value redirects My Docs. So, as part of your network login script, you can achive this automatically by adding in:

reg add “HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders” /v Personal /t REG_EXPAND_SZ /d \\server\%USERNAME% /f

…to redirect to your server using the username of the currently logged on user as the share name.
