    Re: Weird Vista Ultimate networking problem

    Click Start, click Run, and enter into the box that opens: CMD

    In the black box that opens type these three lines, pressing [Enter] on each line:

    regsvr32 netshell.dll
    regsvr32 netcfgx.dll
    regsvr32 netman.dll

    Reboot and test.

    in reply to: XP browsing slow, not 98. No server #174906

    Re: XP browsing slow, not 98. No server

    This is not a DNS issue. DNS registration only becomes important in a Domain. There are large networks that are perfectly happy with Netbios over TCP/IP for name resolution. Similarly, DNS is not used for name resoloution in Workgroups. If you wanted to make it easier to Ping someone on your network, you could make a HOSTS file entry. However, the HOSTS file is not used for NT name resolution. It would do nothing for share browsing. See:
    The difference Between LMHOSTS and HOSTS Files in Windows NT
    http://support.microsoft.com/?kbid=105997

    The HOSTS file does not play a role in LAN name resolution.

    There is no indication of a naming failure for share location. The issue is that share browsing is slow. This is an XP issue related to its search for Scheduled Tasks (and print jobs) and is easily remedied:

    1. Open up regedit.

    2. Navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace

    3. Find a key named {D6277990-4C6A-11CF-8D87-00AA0060F5BF}

    4. Right click on it and delete it.

    5. Restart

    Re: Unable to start XP

    The issue sounds like a corrupt registry.
    This can be repaired by beginning with Recovery Console to “harvest” working images of the registry hives. Then with the computer now able to use these hives to start in Safe Mode, you then use System Restore to upgrade the registry hive images:

    in reply to: ReadyBoost on a CF card #174904

    Re: ReadyBoost on a CF card

    Plug the CF card in and see. It will automatically be recognized, tested, and if it passes you will be offered to make it a ReadyBoost drive.

    This is the best article I have yet to see on ReadyBoost, and I take the liberty of quoting it at length.

    Matt Ayers:

    “I’m the Program Manager in the Microsoft Windows Client Performance group and own the ReadyBoost feature. I wanted to give some offical answers based on the excellent questions and discussions that I’ve seen in this blog, to date. Also, I’ll be using this as a starting point for the official ReadyBoost FAQ.

    Overall, as many posters have pointed out, the feature is designed to improve small random I/O for people who lack the expansion slots, money, and or technical expertise to add additional RAM. As y’all know, adding RAM is still the best way to relieve memory pressure.

    Thanks, again, for your interest, questions and ideas.”



    Q: What perf do you need on your device?
    A: 2.5MB/sec throughput for 4K random reads and 1.75MB/sec throughput for 512K random writes

    Q: My device says 12MB/sec (or 133x or something else) on the package but windows says that it isn’t fast enough to use as a ReadyBoost device… why?
    A: Two possible reasons:
    The numbers measure sequential performance and we measure random. We’ve seen devices that have great sequential perf, but horrible random
    The performance isn’t consistantly fast across the entire device. Some devices have 128M of lightning fast flash and the rest of the device is really slow. This is fine for some applications but not ReadyBoost.

    Q: What’s the largest amount of flash that I can use for ReadyBoost?
    A: You can use up to 4GB of flash for ReadyBoost (which turns out to be 8GB of cache w/ the compression)

    Q: Why can’t I use more than 4GB of flash?
    A: The FAT32 filesystem limits our ReadyBoost.sfcache file to 4GB

    Q: What’s the smallest ReadyBoost cache that I can use
    A: The smallest cache is 256MB (well, 250 after formatting). Post beta2, we may drop it another 10 MB or so.

    Q: Ok… 256M-4GB is a pretty big range… any recommendations?
    A: Yes. We recommend a 1:1 ratio of flash to system memory at the low end and as high as 2.5:1 flash to system memory. Higher than that and you won’t see much benefit.

    Q: Isn’t this just putting the paging file onto a flash disk?
    A: Not really – the file is still backed on disk. This is a cache – if the data is not found in the ReadyBoost cache, we fall back to the HDD.

    Q: Aren’t Hard Disks faster than flash? My HDD has 80MB/sec throughput.
    A: Hard drives are great for large sequential I/O. For those situations, ReadyBoost gets out of the way. We concentrate on improving the performance of small, random I/Os, like paging to and from disk.

    Q: What happens when you remove the drive?
    A: When a surprise remove event occurs and we can’t find the drive, we fall back to disk. Again, all pages on the device are backed by a page on disk. No exceptions. This isn’t a separate page file store, but rather a cache to speed up access to frequently used data.

    Q: Isn’t user data on a removable device a security risk?
    A: This was one of our first concerns and to mitigate this risk, we use AES-128 to encrypt everything that we write to the device.

    Q: Won’t this wear out the drive?
    A: Nope. We’re aware of the lifecycle issues with flash drives and are smart about how and when we do our writes to the device. Our research shows that we will get at least 10+ years out of flash devices that we support.

    Q: Can use use multiple devices for EMDs?
    A: Nope. We’ve limited Vista to one ReadyBoost per machine

    Q: Why just one device?
    A: Time and quality. Since this is the first revision of the feature, we decided to focus on making the single device exceptional, without the difficulties of managing multiple caches. We like the idea, though, and it’s under consideration for future versions.

    Q: Do you support SD/CF/memory stick/MMC/etc.?
    A: Mostly. In beta2, we added support for a small number of SD/CF cards on internal USB2 & PCIe busses. RC1 has a much broader support range.

    Q: Why don’t you support SD on my USB2.0 external card reader?
    A: We unfortunately don’t support external card readers – there were some technical hurdles that we didn’t have time to address. In general, if a card reader shows a drive without media in it (like a floppy drive or CD ROM does), we can’t use it for ReadyBoost.

    Q: Will it support all USB drives, regardless of how they are ID’d to the OS (“hard disk drive” or “Device with Removable Storage”)?
    A: We have no way to tell what is on the other end of a USB cable so we do some basic size checks (since no one has a 200GB flash device ;-) ) and then perform our speed tests. HDD will not, however, pass our speed tests, and there is no benefit to using a USB HDD for ReadyBoost.

    Q: Can you use an mp3 player to speed up your system?
    A: Not currently. MP3 players use the ‘plays for sure’ interfaces to expose themselves to Windows. We require that the device appear as a disk volume. These aren’t currently compatible.

    Q: How much of a speed increase are we talking about?
    A: Well, that depends. On average, a RANDOM 4K read from flash is about 10x faster than from HDD. Now, how does that translate to end-user perf? Under memory pressure and heavy disk activity, the system is much more responsive; on a 4GB machine with few applications running, the ReadyBoost effect is much less noticable.

    Q: I can’t get my device to work with ReadyBoost… can I lower the perf requirements?
    A: Unfortunately, no. We’ve set the perf requirements to the lowest possible throughput that still makes your system faster. If we lowered the perf requirements, then there wouldn’t be a noticeable benefit to using ReadyBoost. Remember, we’re not adding memory, we’re improving disk access.

    Q: Which manufacturers support ReadyBoost?
    A: Well, I hope that all of them do, eventually. Right now, we’re working with manufacturers to create a program that will allow them to identify ReadyBoost capable devices on their packaging.

    I am probably mis-remembering:

    1. GW stood for “Gee Wiz”, why I have no idea. If it stood for “Gee Woz” it would make sense, because it offered floating point, and added the music and video features only then found in Apple Basic (by Wozniak).

    2. COM files have all segment registers set at a starting address of 100, and end with a CD 21 or a JMP instruction to the end of the BIOS where a CD 21 can be found). EXE files have the initials “MZ” as their first two bytes, from one of the original coders of DOS named Mark Z (a Hungarian name I would rather not slaughter).

    Re: NEW CHKDSK /R, problem impossible to solve!

    The notion of using a BART CD as a regular startup method is not a great idea. Two things you can do from boot.ini in order to to have the command line available. Both are likely faster than a BART PE boot:

    • One could add Recovery Console to the Boot.ini, and use Chkidsk /r from the command line.
      You would then at boot be given the choice of Recovery Console or normal XP.

    • Or, you can add an entry to Boot.ini to select a Safe Mode boot with only the Command Shell active.
      (A Chkdsk of the System volume would still require a reboot to perform.)

    in reply to: Cannot View Wireless Network Connections #174895

    Re: Cannot View Wireless Network Connections

    1. Preliminary Steps:

    2. Install Service Pack 2.

    3. Set XP to configure the network settings of the adapter:
    a. Click Start, click Run, type ncpa.cpl, and then click OK.
    b. Click Network Connections.
    c. In Network Connections, click to select your wireless connection, and then click Change settings of this connection.
    d. On the Wireless Networks tab, click to select the “Use Windows to configure my wireless network settings” check box.
    e. Make sure you network adapter does not assume this role of being responsible for the wireless network adapter settings. If so, you can only view available wireless networks through the client software that came with the network adapter driver. It should be possible to disable this, however, and follow the steps above.

    4. To start the Wireless Zero Configuration service, follow these steps:
    a. Click Start, click Run, type %SystemRoot%system32services.msc /s, and then click OK.
    b. Double-click Wireless Zero Configuration.
    c. In the Startup type list, click Automatic, and then click Apply.
    d. In the Service status area, click Start, and then click OK.
    e. Your wireless adapter client software may be set to disable the XP SP2 Wireless Zero Configuration Service. You should be able to disable this feature, however. If the Wireless Zero service is stopped, you will not be able to view available Wireless Networks through the XP interface but only through your network adapter client software.

    5. Now install the Wireless Client Update you downloaded at the beginning. Reboot.

    6. If the steps above do not resolve the issue, please advise the Forum before uninstalling Service Pack 2 again. Usually this implies that one or two utility uses of Netsh.exe need to be run, a trivial task. Specify the make and model of your wireless adapter, and the version of the driver software being used.

    Yes. If you look closely at the journal page by Rear Admiral Grace Hopper pictured above it says: “Moth in Relay. First actual case of bug being found.” Grace Hopper was very proud of her service in the United States Navy. She would often recount being mistaken, in airports, for an airline employee, because of her navy officers’ uniform.

    Re: Documents & Settings folder has domain name appended to username (?)

    User logs in.

    A new folder for their profile is created based on their login name.

    That user’s SID (Security ID; unique to that users account) is recorded in the registry, along with the path of where that users profile is stored.

    If the users profile for example, “Rems”, is already taken it will create Rems.DOMAIN, where domain is the domain you are connected to.

    If Rems.DOMAIN is already being used, it will create a new profile called Rems.DOMAIN.000 and so on.

    The most common reason for this is that the user was created as a console user prior to joining the Domain. It also happens when the User changes from Domain to Workstation, and this is redone back to Domain. It happens when you remove the same username (User Account) and agree to keep all settings. Then re-add the User Account. Windows has to do something, because it is clear to it that the user SID in the existing profile is not identical to the user SID for the user it just authenticated for logon.

    If you are scripting, use this registry location to find the current paths for all valid user profiles:

    This will show all non-standard startup items. It will also show your GPO settings if they involved a registry tattoo.

    See MS-MVP Tony Klein’s fascinating “A collection of Autostart Locations”
    http://gladiator-antivirus.com/forum/index.php?showtopic=24610

    An indispensable tool is AutoRuns by Mark Russinovich and available now at Microsoft/Sysinternals:
    http://www.microsoft.com/technet/sysinternals/utilities/Autoruns.mspx

    With AutoRuns you can easily do a selective disabling of an autorun application or service to debug the process.

    Note that your startup complaint is with access to a file. There is only so many GPOs that effect file system access. Check for restrictions on drives, file extensions, any entries in Restricted applications list, and check entries in Local Security policy to see if you changed the default NTRIGHTS for the user Group — such as loading device drivers.

    Re: Delete multiple shares

    You are going mad because you are equating shares with folders. A single folder could have a hundred shares (and consequently sharenames); and, you can delete those shares without deleting the folder itself. Whether remotely or at an interactive logon on the computer hosting the shares.

    What is discussed above other than in the original post by m80am is deleting folders that are also shared. That is a dfferent task then just deleting shares. As was observed, you can just nuke the folders. While the event will deserve an entry in the Event Log, it is an informative one rather than the indication of anythng fatal.

    in reply to: NEW CHKDSK /R, problem impossible to solve! #174879

    Re: NEW CHKDSK /R, problem impossible to solve!

    If I am not mistaken, rvalstar, this is a client OS subforum. It is confusing matters to take me to task over configuration settings for servers.

    In point of fact:

    1. Scheduled Tasks would be effected by a password change only if the Task was created without specified alternate credentials; and only if Scheduled Tasks are interferred with by your password policy. In this situation you follow Microsoft’s recommendation: you create a user account not subject to password policy and use these credentials for the task. This applies only when a conflicting password policy has been set. This is not a normative situation for client OS installations in non-Domain settings. My suggestion stands as written.

    2. The criticism of alternatively using the All Users Startup location as failing the “lights out” test is absurd in a user OS context. You deny interactive logons in a client OS at your shop? My suggestion stands as written.

    3. You do not chkdsk server drives unless it is a near last resort. So the issue of scheduling one for a server drive is inconceivable to me. This is one excellent way to lose all of your security descriptors due to a well-known and well-documented limitation of chkdsk. Please see the warning from Microsoft:

    Quote:
    CAUSE
    This problem occurs because the Chkdsk utility may not find references to all the security IDs if the master file table is larger than 4 gigabytes (GB) or if there are more than 4,194,303 files on the volume. Therefore, the undiscovered security descriptors are reset.
    Quote:
    MORE INFORMATION
    Even when this hotfix is installed, it is still possible for Chkdsk to reset permissions back to default settings.

    The CHKDSK utility incorrectly identifies and deletes in-use security descriptors in Windows 2000, Windows 2000 Server, Windows XP, Windows Server 2003

    APPLIES TO
    • Microsoft Windows Server 2003, Enterprise x64 Edition
    • Microsoft Windows Server 2003, Enterprise Edition (32-bit x86)
    • Microsoft Windows Server 2003, Standard Edition (32-bit x86)
