    How do I clear the Client Side Cache (CSC)

    Hi

    Having massive problems with CSC

    CSC is not so useful to me as all the data I need to access, lives on a
    RAID array in a Win 2k3.

    Vista won't let me delete the 20+ GB of data in the CSC, I've only just
    found out about it when trying to discover where all my hard disk space
    was going. I've tried turing offline files off, but that doesn't clear
    the cache. The only reference I can find to it on MS support pages
    (http://support.microsoft.com/kb/938092), which says the data in the
    cache is probably ghost files - yes definatly, especially now that I've
    turned offline files off altogether. The support page tells me to
    contact customer support for a hotfix, but considering customer support
    costs 46 for 90 days, frankly I'm appalled.

    Please someone help me

    TIA

    I dunno if I should be helping any Pommies, after England trounced Australia
    in the Rugby. But* ...

    First, did you try to deletete cache using the "official" method?:

    1. Click Start, and then click Control Panel.
    2. Click Network and Internet, and then click Offline Files.
    3. On the General tab, click View your offline files.
    4. In the Offline Files folder, right-click the cache of the offline files
    that you want to delete, and then click Delete Offline Copy.

    That's definitely your first line of attack.

    Next, you may be able to get a copy of the 938092 hotfix for free. Use the
    link below to submit a hotfix request. You'll probably get a reply within a
    few hours (I have, every time I tried it). They will email you a URL from
    where you can download the fix.

    Submit an online request to obtain a Microsoft hotfix
    http://support.microsoft.com/kb/935195

    (Many thanks to John Inzer, for alerting me to this great facility!).

    If you apply the hotfix and it still doesn't solve the problem, or if you
    cannot wait to get the hotfix, you can delete the CSC cache manually. This
    is a bit messy, so not recommended unless totally necessary.

    The files are stored in cache directories, under C:\Windows\CSC

    Normally, access to this directory is limited to the Client Side Caching
    service; not even the Administrator has ownership or any permissions to the
    CSC directory. So, first you need to grant yourself ownership of the CSC
    directory. Once you own the directory, you can then grant yourself
    full-control permissions to the directory, as well - remember to tick the
    option to replace permissions on all descendents, too. Now that you have
    permission, you can go into the C:\Windows\CSC directory, and delete the
    cache. The directory structure will be pretty obvious when you get in there.
    Don't delete the CSC directory itself!! Only the cache sub-directories,
    underneath it.

    If you want to be thorough, you should remove the permissions to CSC from
    yourself again, after you have deleted the files. That will be the secure
    option.

    Hope it helps,

    1st line of attack was unsuccesful, so have submitted request to MS for
    hotfix. I'll wait and see how that goes, then if neccasary will attempt
    your 'messy' solution.

    Thank you very much

    Ruari Mears

    P.S. Sorry about the rugby, but if it's any consolation, I do rather
    like Austrailia and an seriously considering emmigration from this
    police state.

    Hi Andrew

    The MS hotfix did diddily squat, although knowledge of that procedure
    will most likely be useful in the future.

    Your 'messy solution' was the one

    Thanks loads

    Re: How do I clear the Client Side Cache (CSC)

    Here's a trick I use to clear the CSC when I have CSC db corruption or the
    like. I have it saved as csc.reg and just run it in an elevated prompt:
    ---Begin csc.reg---
    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CSC\Parameters]
    "FormatDatabase"=dword:00000001
    ---End csc.reg---
    After restarting my computer, my CSC cache is empty.

    Hey Ruari

    With a good Celtic name like "Ruari", I apologise for associating you with
    the Sassenachs of England Particularly after Scotland went down to
    Argentina the next day.

    Glad the info helps, that's good to know. I must admit, I'll be trying
    Nick's suggestion next time I get a bloated CSC cache.

    Cheers,
