A server is a computer program or a machine that waits for requests from other machines or software (clients) and responds to them. This architecture is called the client–server model. The clients may run on the same computer or may connect to the server over a network. The purpose of a server is to share data or hardware and software resources among clients. Typical computing servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.

There are a few questions I have about a connection I want to make to a shared folder that's on an NTFS volume.  What I wanted to achieve was to have a single, non-admin user account on that target machine to which I only know the password.  The shared folder would give that user account full control while denying full control to all other accounts including administrators.  In other words, if you forget the password, you cannot access the data unless you remove the hard drive itself from the machine.  I would think that this would make it difficult for the likes of Ransomware to encrypt the contents and my backups would be relatively safe.

Next would be to program a backup software to perform nightly backups to this folder.  In this example, I'm using Veeam Endpoint Protection.  The software is programmed with said user account and performs backups nightly.  I'm assuming that while Veeam uses the username and password to open a connection, other programs and users on that originating computer cannot.  In other words, Veeam has a private connection using said credentials.

Is this correct?  Please let me know what you think.

Hello!

I have a PHP script that should create a valid image file on server side. The following code runs fine:
$filename = $_GET['filename'];

// Only proceed if we got valid input
if ($filename !== null) {
    echo "$filename is not null.";
    $image = @imagecreatetruecolor(10, 10)
                or die('Cannot Initialize new GD image stream');

    if (strpos($image, '/gif') !== false) {
        $image_type = "GIF";
        header('Content-Type: image/gif');
        $successful = imagegif($image, "./$filename");
    } else if (strpos($image, '/jpeg') !== false) {
        $image_type = "JPG";
        header('Content-Type: image/jpeg');
        $successful = imagejpeg($image, "./$filename");
    } else if (strpos($image, '/png') !== false) {
        $image_type = "PNG";
        header('Content-Type: image/png');
        $successful = imagepng($image, "./$filename");
    }

    if ($successful) {
        echo "Image written to '$filename'.";
    } else {
        echo "Could not write $image_type image to '$filename'.";
    }
    imagedestroy($image);
    echo "image destroyed.";
} else {
    echo "$filename is null.";
}

Open in new window


This works fine & an image with the $filename is created. But actually, I do not only receive the file name but the image content as well. So, the real code is

$filename = $_GET['filename'];

$image = $_GET['image'];

// Only proceed if we got valid input
if ($filename !== null) {
    echo "$filename is not null.";
    $image = base64_decode($image);
    $slash1 = strpos($image, '/');

    $image_type = substr($image, $slash1, strpos($image, ';') - $slash1);

    if (file_exists($filename)) unlink($filename);

    header('Content-Type: image/' . $image_type);

    switch ($image_type) {
        case "gif":
            $successful = imagegif($image, "./$filename");
            break;
        case "jpeg":
        case "jpg":
            $successful = imagejpeg($image, "./$filename");
            break;
         case "png":
            $successful = imagepng($image, "./$filename");
            break;
    }
    if ($successful) {
        echo "Image written to '$filename'.";
    } else {
        echo "Could not write $image_type image to '$filename'.";
    }
    imagedestroy($image);
    echo "image destroyed.";
} else {
    echo "$filename is null.";
}

But still, I get the reply Could not write image to 't.jpg'. Can you see my error(s)?

Friday, 15/9, the network worked.
After the weekend it is not possible to connect with the server!

There appears to be a problem with the network connection. On the network icon in the process line there is a red cross. But the server can communicate with the Internet.

I have updated driver for network adapter, etc.

Any suggestions?

It's an SBS 2008 with Win7 workstations.

I am curious about finding the cost to a big bank to process something like a bank transfer from one account to another...

I am thinking about my bank, where I have two accounts, where I may move a few hundred dollars from one account to another.

Is the cost less than a penny for such a transaction for a website or an iPhone app to make such a transfer? I assume there are overhead costs where auditors review blocks of transactions, but I am not asking about that. Just the marginal cost for a hosted and highly secure website to process a transaction.

Does anyone have an idea about this?

We have several Remote Desktop Servers (Windows 2008R2) that are optimized as much as we can for the time being. We have budgeted for upgrades but in the mean time, has anyone used RDP Acceleration software such as Ericom, etc with any luck?

Can anyone recommend such a product?

Hi Expert, Please see the attached screenshot. I am installing Solarwinds. but I got an error message. I do not know what SQL server name is to fill the SQL server name. I tried different name including the computer name. During the process of installation, I follow the steps to install, which include automatic SQL installation. Did I miss some step or wrong? Thank you

I’m trying to figure out when to use bitlocker on a server. It makes sense for a laptop or desktop. If they are stolen and the thief can’t login because it is password protected, they could still put the drive in another computer and access the data.

If I have a server in a locked room and there is no concern that it would be stolen, what are the benefits of encryption?

Even if someone did steal the server, it is RAID 5 so it would be a lot more difficult to add the drives to another server to access the data.  It would be easier to run a program to hack the password.

If it is configured to use a pin to start the server, it could not be rebooted remotely. If it shut down for any reason, someone would need to go onsite to start it up. That could create problems especially during storms.

The most likely way someone is going to steal the data from my clients is by tricking a user to install malware. If malware is installed on a workstation, it would be able to access the server whether it is encrypted or not.

Just looking for the pros and cons if encrypting a server

I have been running my Hyper-V Host server on a trial version of server software  and now  has expired .
I have a software with a valid license .
Do I need to back up the VM's Wipe out the server and reinstall Server 2012 ? or is there some way to simply use the new license ?

I am running VEEAM Backup & Replication 9.5 on a Windows Server 2012 R2. VEEAM is configured to backup VM's from 2 Hyper-V Servers that are running Windows Server Data Center 2012 R2. While all VM's backup successfully 'on occasion', often, I get the following error:

Failed to create snapshot (Microsoft Software Shadow Copy provider 1.0) (mode: Veeam application-aware processing) Details: Writer 'Microsoft Hyper-V VSS Writer' is failed at 'VSS_WS_FAILED_AT_PREPARE_SNAPSHOT'
[/b]

I go to the VM Server identified, run the command "vssadmin list writers", and see that a number of VSS entries says 'timed out. I stop/start the Volume Shadow Copy service then restart the server. The backup jog then completes successfully. This issue will occur again after the 2nd or 3rd successful backup and again, I have to restart the server to get successful backups.

Obviously I cannot continue restarting these affected servers (all of which has databases including Exchange Server 2013). Is there anything that would likely cause the VSS services to periodically time out and fail a backup? Thanks

Moving 400G of data with long file paths causing copy issues. What is the best way to automatically move the data whether it be scripts or software? Folder Structure needs to remain intact, long file names can be changed (assuming they are copied into the same folder on the target.)

Thank you.

255.255.240.0 /20

What I want to do is assign another scope within my Security Device Scope for 10 Camera, 10 Card Readers and 2 Media Servers. How would I break that scope up into other scopes for the following devices, however using the Security Device Scope?

Thanks,

Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

In this screenshot what is the exact location of the Test Test user (see the bottom of the screenshot)? Is it OU=users,DC=company,DC=com or is it something else?

The domain name for this organization is company.com

I'm sure this is something simple I've missed but I built a new DC. I enabled Remote Desktop Connections in server manager and I'm unable to get a connection to it. The RDP windows times out before it even sees the DC using FQDN or IP address.

RDP to the new DC was working when my old DC was running so I assumed this was a DNS issue (which would mean RDP to IP would work but it does not).

Any suggestions?

Thanks,
David

Hello -

I am trying to create a query that will give me all my Windows 7 x64 and x86 systems.

What I have is this below, however it doesn't give me the details I want. I want it to list OS, IP, Name, client active or not and whether or not it's a x64 or x86 system.


select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System inner join SMS_G_System_COMPUTER_SYSTEM on SMS_G_System_COMPUTER_SYSTEM.ResourceId = SMS_R_System.ResourceId where SMS_R_System.OperatingSystemNameandVersion like "%Workstation 6.1%" or SMS_R_System.OperatingSystemNameandVersion like "%Windows 7%" and SMS_G_System_COMPUTER_SYSTEM.SystemType = "x64-based PC"

I run this for x86 and it gives me same result as the query above

select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System inner join SMS_G_System_COMPUTER_SYSTEM on SMS_G_System_COMPUTER_SYSTEM.ResourceId = SMS_R_System.ResourceId where SMS_R_System.OperatingSystemNameandVersion like "%Workstation 6.1%" or SMS_R_System.OperatingSystemNameandVersion like "%Windows 7%" and SMS_G_System_COMPUTER_SYSTEM.SystemType = "x86-based PC"

Thanks,

Morning techs,

I work for a large Computer Aided Dispatch software support company.  We supply the HW and SW that runs in Police and Fire Departments all over the world.  

At my Tier, the Tier one we basically gather logs and screenshots from the dispatchers computers to escalate tickets to the Engineers.  There is an error report functionality but the DISPATCHER (whom you know is extremely busy) must MANUALLY run it themselves at time of event.  

Are there any *light* tools out there that can be installed onto the dispatchers computers that would log error reports automatically?

Computers are running Win 7 with just the dispatching SW

Thank you,

I have a customer with a SBS 2003 and the server became infected with the .amnesia infection.  Unfortunately it also attacked many of the servers executable file such as Seagate Backup Exec.  I ran a thorough scan on all workstations.  I installed Microsoft Essentials and Spyhunter on a workstation.  I copied the data folder from the server to a new folder called server on the workstation.  I was told that Spyhunter 4 would detect and remove/repair the infection.  I ran a full scan and it does not seem to see the infected files that are obviously infected because they all have the extension .amnesia.  Does anyone have a recommendation for the repair and removal of this infection in the data files?

Hi

We have SQL database files on the computer Windows 7 Pro x64. We use Asigra for Cloud Backup. Asigra is using VSS backup. The backup started failing a week ago with the error message:
"The process cannot access the file because it is being used by another process." when trying to access .ldf and .mdf files.
I checked the permissions and it is fine. I tried adding exceptions to AVG antivirus but AVG could not access files either.
I used Process Explorer and the files are in use by sqlserv (64 bit) and not sqlserv*32. I checked on another computer we have similar set up and the same backup type and the files over there are not in use by any process.

How can I fix it?
Regards,
Tom
